Dear Business Partners<br />

5G is more than a continuation of the 2G, 3G<br />

and 4G mobile communications standards.<br />

It’s not just about transporting data even<br />

faster and more securely. Instead, the fifth<br />

generation forms a digital nervous system<br />

that takes our interaction possibilities to a<br />

new level. 5G makes communication between<br />

sensors, devices and us easier. Technology is<br />

an important foundation for the Internet of<br />

Things.<br />

To make this happen, investments in infrastructure<br />

are needed, as our FOCUS story<br />

shows. First, mobile network operators have<br />

to upgrade their masts (macro cells) to the<br />

latest state of the art. 5G connectivity can<br />

then be supplemented and condensed using<br />

the smallest cellular base stations (small cells).<br />

But each antenna location has different requirements,<br />

thus challenging creativity when<br />

it comes to finding cabling paths.<br />

Wireless 5G and fiber optic networks have<br />

been growing together for several years now.<br />

Fiber optics are of particular importance in<br />

this context. Fiber optic cabling is more<br />

reliable, more efficient and, above all, more<br />

sustainable than conventional copper cabling.<br />

But it is important to organize the fibers<br />

intelligently because glass fibers and contact<br />

surfaces are highly sensitive.<br />

The new CONEXIO family from R&M is one<br />

of the solutions of the day in this regard. The<br />

modular system makes it relatively easy to<br />

upgrade a macro-cell location. In doing so,<br />

it channels fiber optic, power and hybrid<br />

cabling. In the case of 5G cells in particular,<br />

these solutions have to work even under the<br />

most horrendous environmental conditions.<br />

The CONEXIO family and all-weather<br />

outdoor connectors from R&M meet these<br />

requirements.<br />

Environment-friendly fiber optics<br />

As already mentioned, optical fibers are more<br />

environment friendly than copper cables. They<br />

consist of quartz sand, the mining of which<br />

consumes fewer resources than copper. 5G<br />

and fiber optic networks are connecting more<br />

and more decentralized energy producers,<br />

such as hydroelectric power plants, wind and<br />

photovoltaic plants, and transmit information<br />

about energy production in real time. This<br />

allows municipal utilities to control current<br />

flow intelligently – read more about this in<br />

our TREND report.<br />

Data centers now consume three percent of<br />

the world’s electricity. Sophisticated cooling<br />

management enables them to continuously<br />

improve their energy efficiency. Even small<br />

drafts make a big difference. Solutions from<br />

R&M Tecnosteel are recommended for such<br />

optimization measures. It is worth measuring<br />

and controlling the circulation, temperature,<br />

pressure and humidity in the air of the<br />

computer room. If this data is embedded in<br />

a DCIM system such as inteliPhy from R&M,<br />

the first step towards saving energy has<br />

already been taken.<br />

In the latest issue of our specialist magazine<br />

<strong>CONNECTIONS</strong>, we once again present<br />

innovations – such as our mixed media patch<br />

panel Netscale 48, which offers all cabling<br />

on a single height unit in the rack, or the<br />

new ActiPower 4.0 PDU for data centers<br />

and server rooms, which is available in three<br />

variations. We are also pleased that we will<br />

be able to deliver our new FM45 connectors<br />

from summer onwards: These can withstand<br />

temperatures ranging from -40 to 85 degrees<br />

Celsius.<br />

Furthermore, you will find the latest reference<br />

stories to read, for example about the data<br />

center solution at the multifunctional Kai Tak<br />

Sports Park in Hong Kong and the cabling<br />

of the Olympus medical equipment repair<br />

center in Coimbra, Portugal.<br />

We wish you an inspiring read.<br />

Cabling Megatrend 5G Premises – But How?<br />

With Macro Cell Upgrades to Small Cells<br />

050.7296<br />

5G promises to change the role of cellular phone networks. The fifth generation will<br />

create new economic opportunities and influence social development. But first, providers<br />

will have to set up their macro cells for 5G and create infrastructures for small cells.<br />

New solutions for fiber optic cabling are needed.<br />

Five factors are among the most important<br />

driving forces behind the transition to 5G:<br />

– growing global demand for mobile services<br />

– the continuous development of cellular<br />

technologies<br />

– the emergence of new use cases<br />

– the development of global standards<br />

– the availability of new frequency bands<br />

for 5G<br />

The mini radio cells (small cells) will play a<br />

decisive role in the gradual development of<br />

mobile networks from the predominant 4G/<br />

LTE technology to 5G. They can provide the<br />

high-bandwidth, low-latency connections<br />

required for the potential 5G use cases.<br />

Unique position<br />

Mobile network operators are in a unique<br />

position. They can use their existing networks<br />

and make use of collocated sites for new,<br />

non-standalone 5G sites and expanded 4G<br />

sites. To do so, they need to equip existing<br />

4G macro-cell sites with new and additional<br />

infrastructure elements.<br />

First, network operators will expand their<br />

4G macro-cell locations. These can then be<br />

upgraded with additional 5G small cells in the<br />

form of underlying networks. This enables,<br />

among other things, targeted, local signal<br />

coverage as well as shorter latency times<br />

with the help of the small cell radio heads and<br />

correspondingly compact antenna systems.<br />

Important technical developments for this are<br />

the «massive active multi-input multi-output<br />

antennas» (MIMO) and «beamforming» features<br />

of modern 5G antennas using phase<br />

array technology. Together, these innovations<br />

offer improved network coverage and transmission<br />

capacity as well as an optimization<br />

4 | <strong>CONNECTIONS</strong> 04|2023–<strong>64</strong>

of power management between antennas<br />

and cell phones for uplink and downlink. In<br />

beamforming, the base station generates<br />

highly focused beams to the individual users.<br />

This minimizes interference from other<br />

sources, supports higher data rates that<br />

would otherwise not be possible and, thanks<br />

to improved power management, reduces<br />

battery discharge on the end device side.<br />

Fiber is needed for virtualization<br />

The 5G core network is also evolving with<br />

regard to the compression of network functions.<br />

Centralized and Virtual Radio Access<br />

Network (C-RAN, V-RAN) are the key issues.<br />

In addition, the baseband units (BBUs) from<br />

the cell locations are grouped together in the<br />

network center and operated «in the pool».<br />

This results in a higher demand for fiber optic<br />

capacity in order to connect the centralized<br />

BBUs with their HF radio equipment via<br />

fronthaul connection expansion over a further<br />

distance (10-20 km instead of 100-200<br />

m). The actual additional fiber optic demand<br />

depends on distance and traffic load.<br />

Overall, these topology improvements will<br />

enable faster, more flexible and optimally<br />

scalable networks depending on the load.<br />

While 5G offers new application possibilities,<br />

it also has some important implications for<br />

mobile network operators (MNOs). One of<br />

them, which represents both a challenge<br />

and an opportunity, is the aforementioned<br />

network densification.<br />

to 50 times more antennas compared to 4G/<br />

applications, small cells will be used in both<br />

the medium band and the millimeter band,<br />

depending on the type of environment.<br />

Medium-band small cells (frequencies 3.5<br />

GHz or less than 6 GHz) are best suited for<br />

high density urban areas. With millimeter<br />

waves (28, 33, 66 GHz), MNOs usually work<br />

in highly frequented areas such as stadiums,<br />

airports and pedestrian areas. In addition,<br />

small cells with millimeter waves are also<br />

suitable for fixed wireless access (FWA) or<br />

flexible applications that serve both fixed<br />

network and mobile subscribers.<br />

Focus<br />

The biggest challenges in setting up small<br />

cells include:<br />

– site acquisition (co-located, standalone)<br />

– backhaul connectivity (fiber optic availability<br />

and capacity)<br />

– location-specific fiber optic and power<br />

supply (connectivity and metering)<br />

Using existing systems<br />

As mentioned above, mobile network<br />

operators can use existing infrastructures to<br />

quickly install additional frequencies and thus<br />

new radio cells in certain areas. Three key<br />

challenges have already been met: location<br />

access, backhaul availability/capacity, and<br />

power supply. Access is usually already regulated<br />

by agreements. This saves some of the<br />

time searching for locations and equipment.<br />

Suitable backhaul connectivity is essential for<br />

setting up small cells. It goes without saying<br />

that the fastest possible direct signal trans-<br />

Radio cell planning<br />

First, suppliers must equip the macro cells<br />

with new and additional infrastructures. As<br />

a rule, signal cabling and the power supply<br />

for the existing 4G/LTE technology are<br />

available. The new 5G active technology<br />

and the corresponding cabling must also<br />

be accommodated – taking into account<br />

wind load, load capacity, scalability, supplier<br />

changes and technology upgrades.<br />

The components of 5G fiber optic cabling<br />

should be as compact, lightweight and integrable<br />

as possible and suitable for miscellaneous<br />

location situations. Another decisive<br />

criterion: uncomplicated, fast installation and<br />

the best possible accessibility for maintenance.<br />

030.8335<br />

The cabling solutions must take into account<br />

procedures for the individual upgrading of<br />

existing 4G/5G locations (brown field). They<br />

must also be able to meet demands for the<br />

most standardized design of new 5G locations<br />

(green field).<br />

041.0769<br />

R&M’s CONEXIO FTTA all-in-one solution<br />

In the near future, 5G small cells will be<br />

added as «non-standalone», followed by new<br />

«standalone 5G» locations. They, too, need<br />

multi-fiber links to fiber optic networks at<br />

every conceivable point in the urban, underground<br />

communications network, often in a<br />

sometimes extremely challenging environment.<br />

This calls for a new generation of FTTA<br />

cabling which meets the challenges of 5G<br />

deployment with modular solutions.<br />

030.8322<br />

This makes it easy to install the required<br />

infrastructure and adapt and scale it to the<br />

individual location conditions. Naturally,<br />

components and connectivity in fiber optic<br />

cabling have to be configured for harsh ambient<br />

conditions and have the corresponding<br />

robustness (impact and compressive<br />

strength) and tightness (IP protection).<br />

With CONEXIO, R&M is currently introducing<br />

an all-in-one FTTA solution on the<br />

market (see also page 23). It consists of<br />

CONEXIO lite, flexx and easy. The portfolio<br />

covers fiber optic, power and hybrid<br />

cabling for connecting 4G and 5G radio cell<br />

locations. R&M uses products developed<br />

in-house especially for outdoor connectivity<br />

(IP68, HEC-BR) and outdoor cables in the<br />

fiber optic sector.<br />

In the FTTA area, R&M also offers cabling<br />

solutions with hybrid cables. As a result, the<br />

overall cabling typically requires less space,<br />

the installation effort is correspondingly<br />

reduced and the spatial requirements can be<br />

better consolidated. With correspondingly<br />

farsighted planning, additional optical fibers<br />

and copper strands can be provided in the<br />

hybrid cable. This would prepare the station<br />

for future expansion with additional RRHs.<br />

Macro cell premises, upgrade to 5G<br />

Small cell antenna<br />

port from the cell to the core network must<br />

be ensured. There are several transport solutions<br />

today, including dedicated fiber optics,<br />

wavelength division multiplexing technology<br />

(DWDM), passive optical networks (PON),<br />

DOCSIS and microwave radio. The preferred<br />

solution depends on a variety of factors<br />

and considerations. These include technical<br />

performance, immediate delivery, capacity,<br />

costs and access.<br />

Coordinating cabling<br />

In the future, many additional antenna sites<br />

will have to be connected to core networks:<br />

macro cells, small cells, combined 4G/5G cells,<br />

combinations with public WiFi offerings, edge<br />

data centers and networks for the Internet of<br />

Things (IoT), and other public radio services.<br />

The construction of fiber optic connections<br />

between the backhaul network and antennas<br />

– Fiber to the Antenna (FTTA) – is a complex<br />

matter. Sometimes creative cabling paths<br />

have to be found in the most unusual places.<br />

Public and private telecom operators,<br />

neutral hosts and tower companies will in<br />

some places be forced to merge parts of<br />

their fiber optic networks. The question of<br />

space or wind load can play a decisive role<br />

in installation planning. Network operators<br />

could coordinate their expansion more comprehensively,<br />

saving space, weight and costs.<br />

Together, they could make optimum use of<br />

their infrastructures and resources.<br />

It makes sense to specify the cabling<br />

independently of the application. Application-neutral,<br />

modular and integrated connectivity<br />

solutions are a key issue for solving<br />

the installation challenges of the high density<br />

and intermeshed networks of the future. In<br />

addition, modular active technology and its<br />

software provide various service platforms<br />

concurrently. In this way, the parties involved<br />

create the conditions for a smart future and<br />

optimized interaction between radio cells.<br />

High-quality connectivity<br />

The demand for high-speed mobile communications<br />

is high. Data transmission performance<br />

in the 5G network will increase from<br />

today’s 4x10 Gbit to up to 4x25 Gbit with<br />

typically two SFPs (small factor pluggable) per<br />

remote radio head (RRH).<br />

For cabling, this means: Quality, safety and<br />

performance of cable configurations between<br />

the base station (Base Band Unit, BBU) and<br />

the RRH (remote radio head) close to the<br />

antenna are of crucial importance. If network<br />

operators want to maintain the promised<br />

quality of service, a main focus must also be<br />

on cabling and connectivity.<br />

This applies not only to the fiber optic signal<br />

connection between BBU and RRH, but<br />

also to the demanding power supply of the<br />

RRHs and active antenna systems (Power to<br />

the Antenna, PTTA). Wherever there is 5G<br />

technology, there is also a need for more<br />

power. In the future, the typical power will<br />

be 1,500 watts per sector for complex 5G<br />

antenna systems. Until now, 400 to 500<br />

watts per RRH were sufficient to operate the<br />

antenna systems. Additional copper cables,<br />

ideally with low losses and higher cable<br />

cross-sections, must therefore be planned<br />

and installed for 5G technology.<br />

Along with extra costs for the higher proportion<br />

of copper in the cabling, this also poses<br />

additional challenges. The cabling weighs<br />

more, the wind load increases, handling on<br />

site becomes more laborious. Greater power<br />

also means that larger battery buffers are<br />

required and larger voltage drops on higher<br />

masts must be taken into account.<br />

Conclusion<br />

As we enter the promising 5G era, the infrastructure<br />

of macro and small cells demands<br />

increased attention. Each antenna site places<br />

different, specific demands on fiber optic and<br />

copper connectivity and on integration into<br />

existing infrastructures. Different customer<br />

needs, applications, topologies and environmental<br />

conditions therefore require variable<br />

and varied solutions. A modular system<br />

helps network operators to implement<br />

such site-specific solutions quickly and costeffectively.<br />

A Gem for Sport<br />

at Kowloon Bay<br />

Hong Kong is creating a new gem for sport, the Kai Tak Sports<br />

Park at Kowloon Bay. The iconic center is a shell-shaped<br />

mega-stadium with a pearly shell. The 28-hectare site will be<br />

more than just a breathtaking sports venue.<br />

One hundred companies from all over the world are involved<br />

in the completion, including R&M.<br />

The Hong Kong government calls Kai Tak<br />

Sports Park the most important investment<br />

in sports infrastructure in recent decades.<br />

It is intended to promote the health and<br />

well-being of citizens. Once completed, the<br />

28-hectare Kai Tak Sports Park will be the<br />

largest sports venue in Hong Kong.<br />

A wide range of high-end facilities promotes<br />

«sport for all» and the young sporting talent of<br />

the future. Hong Kong wants to create more<br />

opportunities for local sports students and<br />

top athletes to participate in competitions.<br />

These are the central objectives of the<br />

project.<br />

Hosting major national and international<br />

competitions, the sports park will be the pride<br />

and eye-catcher of the entire city, especially<br />

in 2025, when Hong Kong will host the<br />

National Games together with Guangdong<br />

and Macau.<br />

It was also important for the government to<br />

develop a landscape park for all inhabitants<br />

on the site of the former airport. Here, people<br />

will go out, stroll around, spend their free<br />

time, visit concerts and much more. Kai Tak<br />

Sports Park is said to be a living destination<br />

that promotes positive social interaction<br />

through the power of sport and leisure. The<br />

planners speak of an «urban oasis» that meets<br />

the different needs of the public as well as<br />

professional and amateur athletes.<br />

Suitable infrastructures<br />

Kai Tak Sports Park Ltd. has been implementing<br />

the master plan on behalf of the<br />

government since 2019. It’s going to run<br />

the park for 20 years. The basis is a Design-Build-and-Operate<br />

Agreement (DBO). In<br />

addition to the architectural, constructional<br />

and logistical challenges, it pays particular<br />

attention to the integration of durable and<br />

precisely suitable infrastructures. Among<br />

other things, the planners were looking for<br />

high-quality solutions for data traffic, telephony<br />

and security infrastructure.<br />

A key requirement for the planned data center<br />

and the data and communications network<br />

was that the networks had to be reliable and<br />

provide stable high performance. Providers<br />

should present solutions for outdoor and<br />

indoor cabling, building connections and data<br />

centers.<br />

«The all-in-one connectivity solution<br />

provided by R&M is convincing on all levels.»<br />

Chris Yeung, Owner S-Plux International Limited<br />

All-in-one solution for networks<br />

Together with the local distribution partner<br />

S-PLUX, R&M offered an all-in-one solution<br />

in 2019 that quickly convinced the client. As<br />

a result, the client was able to combine all the<br />

relevant installation services under one roof.<br />

The all-in-one solution primarily comprised<br />

high density cabling for the local area network<br />

and data center. R&M took care of the cold<br />

aisle enclosures and matching patch panels<br />

from the Netscale family. Protective measures<br />

for cables and patch panels were also<br />

part of the solution. R&M integrated the VS<br />

distribution platform for telecommunications<br />

cabling. Technical support is part of the<br />

package.<br />

Digital management<br />

Hundreds of companies from all over the<br />

world and 3,000 team members are involved<br />

in the project. The planners supplied them<br />

with 60,000 drawings. «There is no manual<br />

for us to execute a project of this magnitude<br />

Trends<br />

Small Draft –<br />

Major Impact<br />

030.7927<br />

Data centers already consume three percent of the electricity generated worldwide.<br />

By 2030, they will account for four percent. Cooling consumes half the energy costs.<br />

And that means when data centers want to save costs, use energy more efficiently, and<br />

quickly improve their carbon footprint, they achieve great leverage in cooling.<br />

One of the most important energy-saving<br />

options for data centers is undoubtedly<br />

cooling management. It includes detailed<br />

sensors embedded in an intelligent DCIM as<br />

well as innovative cooling systems and strict<br />

control of airflow.<br />

Even a small and uncontrolled draft has a<br />

major impact. The countless gaps, holes and<br />

slots in the racks allow a lot of cooling air to<br />

flow away uselessly to the side. According<br />

to Graphical Research*, typical data centers<br />

waste up to 50 percent of the cooling airflow.<br />

This flows unused into the computer room<br />

or back to the CRAC/CRAH fans instead of<br />

flowing through the racks and IT equipment.<br />

Many operators generate a low-temperature<br />

climate of 16 to 18 degrees Celsius in the<br />

computer room in order to achieve a cooling<br />

effect based on outdated models. Some<br />

run fans at high speed. Others allow warm<br />

exhaust air from the rear side of the racks to<br />

circulate into areas that should remain cool.<br />

Indispensable enclosures<br />

Closed enclosures or curtains can strictly<br />

separate the rack corridors into cold aisle<br />

and warm aisle. They ensure that the cold air<br />

flowing from the sub-floor stays in the cold<br />

aisle first. This is indispensable in larger data<br />

centers today. The BladeCube enclosures in<br />

combination with T7 BladeShelter cabinets<br />

from R&M Tecnosteel are sophisticated<br />

solutions.<br />

It comes down to small, simple details to<br />

ensure cold and warm air no longer mix. The<br />

cable guides can be sealed with brushes.<br />

Cleverly constructed brackets, screens,<br />

lamellas, lips and dummy plugs close gaps and<br />

empty slots in the racks. Market researchers<br />

from Gartner* say that seals that are not<br />

technically complex can save ten percent of<br />

the power consumption for cooling.<br />

Every percent more perforation in the front<br />

and rear doors of cabinets helps to avoid<br />

congestion and hotspots. R&M’s T7 cabinets<br />

10 | <strong>CONNECTIONS</strong> 04|2023–<strong>64</strong>

each a record with 82 % perforation. Inside<br />

the cabinets, additional lateral air ducts and<br />

sensor-controlled fans can optimize the cold/<br />

warm airflow.<br />

Hyperscalers are already dispensing with<br />

raised floors. They build on hard ground to<br />

maximize packing density. Side and inline<br />

cooling units supply the cold air. It is important<br />

to ensure constant air pressure and stable air<br />

circulation and ensure that there is sufficient<br />

airflow throughout the aisle to prevent<br />

overheating at the end of a row. Multi-cloud<br />

providers confirm that a well-managed cold<br />

aisle containment requires an estimated ten<br />

percent less energy.<br />

030.7939<br />

Modular enclosures, such as BladeShelter<br />

from R&M Tecnosteel, can even be integrated<br />

into brownfield infrastructures. It may<br />

therefore be worth exploring and exploiting<br />

the potential for optimization in an existing<br />

computer room.<br />

Gartner believes it is possible to reduce the<br />

share of air conditioning in energy consumption<br />

to 15 percent. Today, it is usually 35 to<br />

50 percent. Further targeted thermal, fluidic<br />

and design measures are required as well as<br />

continuous efficiency increases.<br />

030.8060<br />

The PUE value<br />

Power Usage Effectiveness (PUE) is the<br />

name of the most important indicator of<br />

the energy efficiency of data centers. It<br />

expresses the relationship between the<br />

electricity fed in and the energy used<br />

to operate the IT equipment in the data<br />

center.<br />

The lower the PUE value, the more climate<br />

friendly and power efficient the<br />

plant. With a theoretical PUE value of 1,<br />

the entire power goes to the computers.<br />

With a PUE value of 1.2 or 1.3, a data<br />

center is considered «green». Here, 20<br />

or 30 percent flow into processes such<br />

as cooling or air conditioning rather than<br />

processing power. Conventional data<br />

centers have a PUE value of 1.9. This<br />

means that almost half of the total energy<br />

consumption is not used for the actual<br />

purpose – i.e. processing power.<br />

Saving with cooling modules<br />

One effective step is the installation of compressed,<br />

innovative cooling modules. They<br />

are placed to the side of rows of cabinets,<br />

inside the rows or on the rear side of cabinets.<br />

They require little surface area and current,<br />

and are close to the heat sources.<br />

According to Graphical Research*, rack and<br />

row cooling modules allow cost savings of<br />

up to 30 percent. They can be implemented<br />

up to 60 percent faster than conventional<br />

circulating air solutions. In addition to water,<br />

ammonia, propane and CO 2<br />

are also suitable<br />

coolants. With its BladeCooling family, R&M<br />

Tecnosteel offers gas- and water-cooled<br />

modules with open and closed circuits.<br />

It could be warmer<br />

How much cooling should there be? This<br />

is a controversial issue. The server room<br />

temperature is 22 to 25 degrees Celsius<br />

as standard. Many data centers are already<br />

working at operating temperatures above 25<br />

degrees without overheating or IT failures.<br />

Innovative liquid cooling systems enable<br />

operation with water at a temperature of<br />

50 to 70 degrees Celsius. Under certain<br />

conditions, heat recovery is possible to heat<br />

neighboring buildings. The Swiss provider<br />

Green Datacenter AG is setting a good<br />

example, supplying several thousand homes<br />

with district heating.<br />

Not all climate friendly measures are<br />

worthwhile for every data center. It is always<br />

important to check what suits your own<br />

system best. In any case, data centers should<br />

monitor the circulation, temperature, pressure<br />

and humidity of the air in the computer<br />

room across the board. The speed and wear<br />

of the fans must also be monitored. Efficiency<br />

cannot be evaluated and improved without<br />

this data, which a holistic DCIM system such<br />

as R&M inteliPhy net has to process.<br />

Saving with More Fibers<br />

in a Small Space<br />

060.2128<br />

The cornerstones of the R&M product portfolio for Fiber-to-the-Home networks<br />

include ribbon solutions for the SYNO splice closure portfolio. They combine<br />

the advantages of innovative SYNO gel sealing technology with R&M ribbon fiber<br />

management technology.<br />

The direct connection of modern data centers<br />

and forward-looking smart city concepts is<br />

leading to ever higher fiber densities with<br />

corresponding amounts of data and thus to<br />

more complex networks. Nowadays, trillions<br />

of bytes of data are already being produced<br />

worldwide every day. As a result, the demand<br />

for fiber optic connections is increasing<br />

significantly. But because the space for such<br />

cabling routes is scarce, the cabling has to<br />

be compacted. Ribbon fiber cables are used<br />

to cope with these fiber densities. Thanks to<br />

their special design, the multi-fiber cables are<br />

more compact than traditional multi-fiber<br />

optical fiber cables. With special devices,<br />

they can also be spliced in parallel and faster<br />

than conventional central loose tube cables,<br />

which shortens installation time and thus<br />

reduces labor costs. Typically, ribbon fiber<br />

cables consist of bands with four, eight or<br />

twelve fibers each.<br />

Fiber distribution system – modular<br />

and high density<br />

The R&M ST500 optical distribution system<br />

is adapted to this. The integrated «heat shrink<br />

splice holders» for ribbon fibers and single<br />

fibers allow the use of various cable types in<br />

the same splice trays. In combination with the<br />

STH-500-R splice holder, 144 (12x12) fibers<br />

can be reliably and easily supplied in ribbon<br />

technology or, with the STH500-S variant,<br />

24 fibers in single fiber management. Stacks<br />

of up to eight such splice trays, secured with<br />

Velcro tape, can be realized in a SYNO ribbon<br />

closure, thus resulting in a maximum number<br />

of 1,152 (ribbon) or 192 (single) fibers.<br />

In the splice closure, the ribbon fibers are<br />

guided to the respective splice tray through<br />

specially attached flexible pipes. Overlengths<br />

are stored in a freely accessible loose tube<br />

tray (splice basket).<br />

More splices in the splice closure<br />

The new features of ribbon fiber management<br />

strengthen the successful SYNO splice<br />

closure family and support R&M customers<br />

with rollouts of corresponding fiber optic<br />

030.6336<br />

030.7748<br />

networks. In addition to saving space for<br />

cable routing, the high splice and fiber density<br />

of ribbon cables is a key success factor in<br />

optimizing working time and costs.<br />

The SYNO gel closure has eight entry bays<br />

at the bottom, which can be fitted with cable<br />

entry kits for cables with a diameter of 2 to<br />

28 mm or for micro ducts with a diameter<br />

of 5 to 14 mm if the blow-in technique is<br />

used. The splice closure configuration can<br />

be adapted to individual requirements. As a<br />

result, network operators can not only plan<br />

more individually and at shorter notice, but<br />

can also retrofit with a manageable amount<br />

of effort.<br />

Clever: The SYNO gel seal protects the valuable<br />

content by adapting to the cable diameters<br />

and the cable geometry. The integrated<br />

gel blocks are easy to open and exchange.<br />

In turn, the cable gripper is fastened in a user-friendly<br />

manner, outside the splice closure.<br />

An additional plus: The inner mechanisms of<br />

the dome closure remain undisturbed and<br />

protected during assembly work.<br />

All cables are reliably strain-relieved individually<br />

in just a few steps. Once they have<br />

been prepared, the strain relief clamps can<br />

be mounted in next to no time. Uniform<br />

clamping all around the cable jacket ensures<br />

stress-free absorption of traction and torsion.<br />

Time pressure, lack of material, spontaneous changes of plan, complex IT<br />

infrastructures and sensitive migrations. These are the daily challenges faced<br />

by the team at Joyce Solutions.<br />

Trends<br />

Comprehensive Protection<br />

of Fiber Optic Networks<br />

Fiber optic cables in public spaces form the backbone<br />

for the broadband supply of entire countries. They are<br />

often easily accessible in shafts, ditches, tunnels or<br />

on buildings and railway lines. This makes their protection<br />

all the more important.<br />

050.7307<br />

Fiber optic cables are easily accessible during<br />

above-ground cable laying. This makes it all<br />

the more important to pay attention to their<br />

protection and safety.<br />

The security risks for public fiber optic networks<br />

are increasing. The enormous growth<br />

in the number of cables, street cabinets,<br />

splice closures, and domestic cut-ons creates<br />

a higher risk potential. The risks range from<br />

improper handling through eavesdropping<br />

attempts and disasters to vandalism and sabotage.<br />

Security-conscious network managers<br />

should pay attention to the following points.<br />

Seamless documentation<br />

Documentation: If you have a seamless and<br />

timely record of where and how cables have<br />

been laid and which points they connect,<br />

you can react in a targeted manner in the<br />

event of a failure. Failure scenarios, alarming/<br />

warning processes, maintenance intervals,<br />

measurement results, etc. should always be<br />

precisely documented. R&M inteliPhy net can<br />

help with this.<br />

Bending radii: Optical fibers are sensitive<br />

to bending. Bends that are too severe and<br />

too frequent dampen signal transmission.<br />

During installation, strict attention must be<br />

paid to the bending radius of the cables and<br />

sufficient fiber reserves.<br />

Dust and water: Fiber optic connections<br />

must be dust-free, as dust interferes with the<br />

transmission of light at the contacts. Moisture<br />

can also have a detrimental effect. In<br />

underground line construction, longitudinally<br />

watertight cables with fillings made of gel or<br />

spring yarn should be used. Blind-mating<br />

solutions, such as the HEC coupling from<br />

R&M, help to prevent dirt ingress in aboveground<br />

cable laying.<br />

Reinforcement: Cables may be touched<br />

during ground work or attacked by rodents.<br />

Strong reinforcement in the cable jacket and<br />

resistant pipes provide protection.<br />

Access: Cabins, shafts and raised floor distributors<br />

must be locked in such a way that<br />

only authorized persons can open them. At<br />

safety-critical premises, additional armor<br />

or impact-resistant housing, fences with<br />

barbed wire crowns and lowered pipes are<br />

recommended.<br />

Eavesdrop protection: Optical fibers can<br />

be tapped using optical splitters or bending<br />

couplers. With active fiber monitoring (AFM)<br />

or OTDR measuring, changes in light transmission<br />

can be localized over long distances.<br />

In order to fully exploit the potential of fiber<br />

optic cabling, it is important to take these<br />

points into account during the design, planning<br />

and installation phase as well as during<br />

ongoing operation.<br />

Fiber optic cabling on mobile communication<br />

antennas is often only protected by a fence.<br />

050.7308<br />

In FTTH cabling, protection against possible<br />

damage plays an important role. The cables and<br />

splice closures are just below the ground or in<br />

the road shaft.<br />

Redundancy: When active and passive<br />

redundancy in the fiber optic network is<br />

planned with foresight, downtime can be<br />

minimized or automatically prevented.<br />

HEC-BR and HEC-QR –<br />

a Strong Duo<br />

050.7255<br />

The 5G trend calls for fiber optic connectors that can withstand<br />

a lot. They have to ensure secure connections between radio<br />

heads and networks outdoors on the many new antennas.<br />

That’s why R&M has developed strong outdoor connectors.<br />

Fiber optics is increasingly replacing copper<br />

cabling over short distances, even outdoors.<br />

This allows users to set up more powerful<br />

data transmission which is much-needed.<br />

The demand is particularly high in the many<br />

new 5G cells and public WiFi infrastructures.<br />

Broadcasting, transport, mining and industry<br />

are also increasingly focusing on data transmission<br />

using fiber optics in outdoor areas.<br />

The trend presents manufacturers with challenges.<br />

The FO fibers and contact surfaces<br />

are sensitive. They must be protected from<br />

hazards that rarely occur in main distribution<br />

cabinets: extreme temperatures, vibrations,<br />

salt mist, dirt, moisture. The connectors must<br />

also be able to be installed safely and without<br />

error whatever the environment.<br />

Universal housing<br />

Solutions for outdoor connectivity in the<br />

FTTx and aerial segments have been part of<br />

R&M’s expertise for decades. One focus is<br />

on modular distribution platforms for public<br />

networks, with the HECs (Harsh Environment<br />

Connectors) providing benefits down the line.<br />

The range initially consisted of the HEC-BR<br />

with a quarter-turn fastener and 32 mm<br />

diameter. In the future, there will also be the<br />

HEC-QR with a Quick Release mechanism<br />

and 19 mm housing for higher packing<br />

density at the place of use.<br />

HEC housings accommodate LC, SC and<br />

MPO connectors. They are decoupled from<br />

the cable strain relief in the housing, which<br />

means the plugged ferrules are not affected<br />

by temperature fluctuations, cable shrinkage<br />

and mechanical influences. The push-twistpull<br />

coupling on the HEC-QR needs to be<br />

turned slightly counterclockwise, which prevents<br />

unintentional unlocking by operators,<br />

plants and animals.<br />

R&M tests the HECs in accordance with<br />

«Telcordia GR 3120 and IEC 61753-1<br />

Extreme Environment Category». They are<br />

UV-resistant and configured for -40°C to<br />

+85°C and protection class IP68. With a<br />

tensile stress of up to 450 N, they are among<br />

the strongest outdoor connectors in their<br />

class. The protective caps for HEC adapters<br />

R&M has now implemented its experience<br />

in the outdoor installation of fiber optics<br />

in the design of the HEC housings. This<br />

results in strong connectors that are easy<br />

to install in harsh environments.<br />

and connector housings are compatible and<br />

can be fitted against each other to prevent<br />

contamination.<br />

Blind mating<br />

The «blind mating» assembly technology<br />

developed by R&M is just as convincing.<br />

HEC connectors can be mated by someone<br />

without a direct view who is wearing gloves<br />

and working one-handed, without the end<br />

face being dirtied or scratched.<br />

Success<br />

A Milestone<br />

for Olympus<br />

050.7312<br />

In the midst of the pandemic, Olympus resolutely had a new industrial facility built<br />

in Coimbra. It is one of the largest medical device repair centers in Europe. R&M and its<br />

Portuguese partner GAP made a decisive contribution to the success of the project.<br />

The center went into operation in September 2022.<br />

The Japanese Olympus Group has based<br />

one of its biggest medical repair centers at<br />

its Coimbra site in the heart of Portugal.<br />

Olympus invested 32 million euros in the<br />

building plus two million euros in a climate<br />

friendly solar system. For Olympus, this is<br />

a long-term investment in a strategic site<br />

and a milestone on the way to becoming a<br />

world-leading medical technology company.<br />

Demand for medical device repair services<br />

is growing. Around 15,000 appliances are<br />

currently repaired in Coimbra each year.<br />

By 2024, the number is expected to rise to<br />

30,000 per year.<br />

Medical technology sets<br />

new standards<br />

The repair center fulfills industry standards<br />

that meet the special conditions of medical<br />

Solid data network required<br />

Project management called for a solid data<br />

network to support the diverse requirements<br />

and services of the repair center. Other<br />

criteria were:<br />

– Functionality: Olympus wants to use the<br />

LAN not only for data processing, quality<br />

management, the ERP system and Internet<br />

applications. It is also intended to support<br />

significantly more functions and applications.<br />

Among other things, CCTV monitoring,<br />

the control of technical equipment and<br />

industrial applications are to be integrated<br />

into the LAN.<br />

«Successfully finishing this project in the middle of<br />

the COVID19 pandemic was an amazing logistic, health<br />

and human resources challenge. The partners DST, DTE<br />

and GAP did it in a perfect way with the support of<br />

R&M and the customer Olympus.»<br />

– Future viability: In conjunction with<br />

strategic investment planning, the passive<br />

network infrastructure was to have reasonable<br />

reserves. The data network was to be<br />

configured for the growth of repair services<br />

from the outset.<br />

– Distributors and cabling were to be configured<br />

for decades of sustainable operation<br />

and to support future IT generations.<br />

– «Top quality» was another selection criterion<br />

for the network technology.<br />

– Ability to deliver: Project participants<br />

should adhere to a fixed schedule. The<br />

availability of skilled workers and the necessary<br />

materials should be reliable.<br />

Olympus chose GAP LDA as its partner, an<br />

experienced, innovative and leading Portuguese<br />

engineering, installation and service<br />

company based in Lisbon. Founded in 2004,<br />

the supplier combines expertise in copper,<br />

fiber optic and measurement technology for<br />

data and communications networks. GAP is<br />

a certified R&M partner.<br />

Cooperation in planning<br />

GAP was awarded the contract to develop<br />

and implement the entire network with fiber<br />

optic backbone and Cat. 7 A<br />

/Cat. 6 A<br />

copper<br />

technology. The GAP team worked together<br />

with R&M from an early stage of planning.<br />

Specialists from dst s.a., a leading planning<br />

office for large construction and infrastructure<br />

projects in Portugal, provided technical<br />

support. Olympus had commissioned dst s.a.<br />

with the overall supervision of the construction<br />

Trends<br />

Coherence –<br />

a Way to More Powerful Transmission<br />

050.7317<br />

Coherent optical communication has been on the technological radar for some<br />

time now. The promise of longer reach and much higher capacity is enticing, but<br />

what does it really mean for networks and their deployments?<br />

The communication protocols currently<br />

used (NRZ, PAM4, etc.) are based on the<br />

modulation of light intensity. Detectors at<br />

the receiving end can measure the optical<br />

power and translate this into a digital signal.<br />

Coherent optical communication technology<br />

differs significantly from this scheme. Here<br />

both transmission and detection are based<br />

on different principles.<br />

For the transmission, an optical beam is split<br />

into its orthogonal light polarizations, and the<br />

phase of one of them is modulated before<br />

recombining them again into a single beam.<br />

This beam is then transmitted via optical fiber.<br />

Different detection<br />

The core difference in the technology lies<br />

in the detection scheme. This detection is<br />

no longer based solely on measuring the<br />

power of the arriving optical signal; instead,<br />

it splits the arriving signal into its orthogonal<br />

polarizations again and combines it with a<br />

local light source.<br />

This amplifies the signal-to-noise ratio<br />

significantly. The sensitivity of the system is<br />

improved by 20 dB or 100 times better than<br />

traditional transmission systems.<br />

Longer distances<br />

This means a signal can travel considerably<br />

longer distances under the same conditions.<br />

The achievable distance for coherent communication<br />

is in thousands of kilometers<br />

as opposed to a few tens of kilometers for<br />

regular non-coherent transmission.<br />

Although the transmission and detection are<br />

based on a manipulation of the polarization<br />

of light, this happens inside the coherent<br />

optical modules. After the recombination and<br />

coupling of the beam into the optical fiber,<br />

the propagation of light in the network does<br />

not require polarization-maintaining fibers or<br />

any particular connectivity enhancement.<br />

In other words, a much denser and far-reaching<br />

signal can be sent using the same path;<br />

the tradeoff, of course, is the complexity and<br />

price of the optical modules.<br />

«Both webscale and telco operators are making<br />

fundamental changes to their network architectures<br />

due to the availability of pluggable 400G coherent<br />

modules. »<br />

while the second is a QSFP DD ZR solution<br />

While a 100G LR optical module can be<br />

obtained for a few hundred US$ (based<br />

on 4 lanes), the price of a digital coherent<br />

optics (DCO) module is approximately US$<br />

7,000 at the time of writing (based on 100G,<br />

single lane, QSFP-DD). It is easy to see that<br />

the return on investment depends on the<br />

application.<br />

Profitable use cases<br />

The obvious application for coherent optical<br />

communication technology is long-haul links.<br />

Whereas previously, it would be necessary to<br />

place a repeater every few tens of kilometers,<br />

now high-bandwidth intercity links are possible<br />

with a single coherent module.<br />

Coherent optical communication can also be<br />

used to upgrade the backbone network and<br />

to provide mid-haul 5G backbone.<br />

One less obvious application is starting to<br />

gain momentum; coherent communication<br />

for the interconnection of hyperscale data<br />

centers and next-generation cloud services.<br />

Here, coherence technology would be a<br />

solution to leverage existing fiber optic connections<br />

on a campus or in a metropolitan<br />

area between distributed sites.<br />

For this application, coherent communication<br />

competes with other technologies proposed<br />

Increasing shipments<br />

Several companies have released coherent<br />

optical communication products. One example<br />

for point-to-multipoint communication<br />

was shown by Infinera at ECOC 2022 in<br />

In this approach, several individual transceivers<br />

Copper and Fiber Optics<br />

Cleverly Combined and Monitored<br />

030.7513<br />

IT and infrastructure managers have to achieve ever greater performance at lower costs<br />

in data centers – and with increasing flexibility. This is exactly what R&M designed its<br />

copper and fiber optic patch panel Netscale 48 for.<br />

Whether in offices, edge and colocation<br />

data centers, at wholesalers and retailers, for<br />

example, in the computer room – copper and<br />

fiber optic lines have to be cabled flexibly,<br />

usually in the tightest of spaces, but still<br />

neatly. The modular and high density R&M<br />

mixed media panel with its cable management<br />

system accommodates everything in a<br />

single height unit in the rack to save space.<br />

Cable tangle is a thing of the past for all types<br />

of copper and fiber optic connections.<br />

Both technologies can be connected<br />

cost-efficiently in the same height unit and<br />

create systematic order. This is because R&M<br />

supplies the standardized, but also individually<br />

plannable, pre-terminated Netscale 48<br />

sets fully equipped. This saves time during<br />

installation. The panels also score well in<br />

use, when upgrade, maintenance and repair<br />

measures are required.<br />

Flexible and intuitive installation<br />

The tray-fitted copper and fiber optic trunk<br />

cables support LC, MPO, SC and E-2000<br />

as well as Cat. 6, Cat. 6 A<br />

and the latest Cat.<br />

8 copper connectivity. In addition, the new<br />

connection options are available with a high<br />

number of fibers, such as SN, CS, MDC as<br />

well as the new MPO16. A standard tray<br />

allows use in all slide-in positions – regardless<br />

of whether the patch panel is straight or<br />

angled. An additional plus: All current fiber<br />

optic connectors can be connected in the<br />

same panel. The tray system has a modular<br />

design so that slots can be freely selected.<br />

away in an orderly and space-saving manner,<br />

both at the front and at the back.<br />

With the appropriate inteliPhy net AIM<br />

system from R&M, which can be expanded<br />

at any time, additional security is added to<br />

the ordered all-in-one solution.<br />

Another good argument to conclude:<br />

Netscale not only stands for maximum port<br />

density, but R&M can offer a five-year product<br />

warranty and a 25-year system warranty<br />

thanks to its robust design.<br />

Mounting the trays is easy: Thanks to their<br />

snap lock system, technicians can install and<br />

matter of seconds in just a few steps without<br />

special tools. Very intuitive – and safe: Despite<br />

the snap function, ground bonding is<br />

guaranteed at all times. The cables are routed<br />

Raring to Go<br />

FTTA is just as much a part of 5G as broadband is part<br />

of the digital era. But how can FTTA be implemented<br />

as easily, individually and cost-effectively as possible?<br />

R&M’s answer is CONEXIO and is now launching.<br />

030.8321<br />

The macro cells for the new radio-based highspeed<br />

data traffic require stable, outdoor-capable<br />

fiber optic infrastructures (Fiber to the<br />

Antenna = FTTA). From the core network and<br />

base stations to the radio head, the cabling<br />

has to meet numerous requirements.<br />

Mobile operators and tower companies<br />

are looking for solutions for a wide range<br />

of location situations and topologies. They<br />

want to move forward quickly and cost-effectively.<br />

And they need robust, easy-to-install<br />

products.<br />

R&M is now providing an appropriate modular<br />

system with the new CONEXIO family. It<br />

includes all the modules that operators need<br />

for connecting, converting and upgrading<br />

macro-cell sites. These include boxes, cable<br />

head terminals, dividers, jumper cables and<br />

outdoor connectivity.<br />

More than FTTA<br />

CONEXIO can do more than Fiber to the<br />

Antenna (FTTA). The R&M modular system<br />

also offers solutions for Power to the Antenna<br />

(PTTA) and hybrid connectivity (HTTA).<br />

Therefore, CONEXIO is a complete system<br />

for site- and operator-specific infrastructures<br />

of macro cells. CONEXIO is also a plug-andplay<br />

solution.<br />

R&M has done everything to make it easy<br />

for installers to install, maintain, extend and<br />

replace the boxes, cable head terminals,<br />

dividers, connectivity and jumper cables. This<br />

reduces the cost of labor. The new HEC-BR<br />

(Bayonet Release) outdoor connectors<br />

feature unmatched failure safety and can be<br />

coupled quickly, even with gloves.<br />

The CONEXIO development is based on<br />

R&M’s decades of experience in equipping<br />

telecom and FTTX networks.<br />

Global market launch<br />

The market launch will take place globally.<br />

The R&M network ensures that the products<br />

are available everywhere and meet global<br />

The transition to a cashless Europe is progressing relentlessly.<br />

Payment service providers such as Nexi are spending a lot<br />

of time and money expanding their data centers. This is the<br />

only way to meet the rapidly increasing demand for digital<br />

services. Nexi is expanding the rack rows in an efficient way.<br />

Nexi, the European market leader in the<br />

sector, wants to innovate digital payments.<br />

The provider strives for a comprehensive and<br />

personalized range of payment solutions of all<br />

types. «We will drive forward the transition to<br />

a cashless Europe and make every payment<br />

digital, as it is easier, faster and safer for<br />

everyone,» states the Milan-based company<br />

of its goals.<br />

Demand for digital banking services is growing<br />

considerably. Regulatory and compliance<br />

requirements are evolving. Nexi is responding<br />

by scaling computer power, modernizing<br />

technology, and making digital payments<br />

increasingly secure.<br />

As part of its business strategy, Nexi is<br />

converting its own technology platform into<br />

a hybrid cloud architecture. Every year, the<br />

company invests more than 800 million euros<br />

in IT and innovations. In addition to technology,<br />

the expertise and energy of the employees<br />

contribute to Nexi’s leading position.<br />

Saved from high costs<br />

The infrastructure in the computer halls is<br />

also growing. Rack rows need to be expanded<br />

or adapted on an ongoing basis. When eight<br />

racks were to be replaced in 2018 due to<br />

design disadvantages, the team at Tecnosteel<br />

recommended deepening the installed racks<br />

during operation and thus preventing an<br />

interruption to business. That was 16 times<br />

more economical than having them replaced.<br />

This success has led to the development of<br />

a trusting, long-term business relationship.<br />

Nexi ordered a total of 80 racks and 160<br />

monitored PDUs in three consecutive rounds<br />

The racks are manufactured at R&M Tecnosteel<br />

in Brunello, the BladeShelter team<br />

manages the project and configures the racks,<br />

and a distributor takes care of storage and<br />

logistics.<br />

Why R&M?<br />

– Infrastructure solution (cabinet, PDU)<br />

and configuration from a single source<br />

– Cost-saving design solution<br />

– Product quality<br />

– Personal trust<br />

– Expertise, planning, service<br />

Nexi is Europe's PayTech, present in<br />

high-growth European markets and<br />

technologically advanced countries. The<br />

company has the scale, geographic reach<br />

and capabilities to lead the transition to<br />

a cashless Europe. With its portfolio of<br />

innovative products, ecommerce expertise<br />

and industry-specific solutions, Nexi<br />

is able to provide flexible support for<br />

the digital economy and the entire global<br />

Saving Energy<br />

with Fiber Optics?<br />

Although fiber optic networks cannot transfer power, they do offer a number of advantages<br />

for switching to renewable energies. They form the framework that facilitates smart power<br />

saving for countries, cities, municipal utilities and industries.<br />

The aim is to replace fossil fuels with sustainable<br />

and renewable energy production. This<br />

is a key objective of global initiatives that aim<br />

to protect the climate. For example, EU states<br />

want to increase the share of renewable<br />

energies in their total consumption to at least<br />

32% by 2030. This can only be achieved if<br />

the power supply infrastructure is expanded,<br />

adapted and equipped with intelligence.<br />

In the future, the electricity network will connect<br />

more decentralized energy producers,<br />

such as hydro and wind power plants, solar<br />

fields and local photovoltaic systems. Utilities<br />

need to know in real time how much these<br />

energy sources can feed into their grid. They<br />

need to be able to intelligently regulate the<br />

flow of electricity over long distances just as<br />

quickly so that the grid remains stable.<br />

«Fiber optic networks can help speed up the transition<br />

to renewable energies.»<br />

Extensive 5G and fiber optic networks can<br />

provide the necessary data traffic. However,<br />

fail-safe, weather-resistant FO connections<br />

must be installed at the many power plants.<br />

Aiming for the smart grid<br />

Energy consumption and stationary energy<br />

storage systems on customer premises must<br />

also be managed intelligently and in real time.<br />

In this way, energy-saving potential can be<br />

exploited, a stable power supply ensured and<br />

price advantages put to good use. For this<br />

purpose, municipal utilities need many monitoring<br />

systems, sensors and remote control<br />

directly on electricity consumers’ premises.<br />

A Space-Saving Miracle<br />

in the Netscale Portfolio<br />

030.8218<br />

The flexible mixed media patch panel Netscale 48<br />

from R&M with cable management system<br />

offers all cabling on a single height unit in the rack.<br />

The panel is now also available in two and four<br />

height units.<br />

030.83<strong>64</strong><br />

Greater performance at a lower cost – this<br />

is the challenge faced by every infrastructure<br />

manager today. Whether for LAN office<br />

cabling in industry or in edge and colocation<br />

data centers. This is precisely why R&M<br />

has equipped its fiber optic platform with a<br />

new system solution. The multi-height unit<br />

panels for two and four height units can be<br />

installed faster and thus reduce assembly and<br />

expenditure.<br />

As with Netscale 48, the full range of<br />

functions is available in one height unit,<br />

which simplifies all installation activities. An<br />

additional plus is the familiar intuitive handling.<br />

Everyone benefits in some way from<br />

these advantages: The planner gets along<br />

with less construction work, the purchasing<br />

department requires fewer quantities, and<br />

the logistics department fewer packages.<br />

Installers need fewer screws, which means<br />

they are faster and have less packing waste.<br />

And finally, the operator benefits from less<br />

expensive purchasing.<br />

Best maneuverability as usual<br />

The robust panels, which are available as a<br />

straight version, are available with all fiber<br />

optic and copper trays and modules, including<br />

a single splice solution. The new single<br />

splice tray, which enables classic termination<br />

in the rack, offers a single termination for<br />

twelve fibers.<br />

The multi-height unit panel also cleverly<br />

combines two technologies in one system:<br />

copper and glass connections. They can<br />

be mounted in the same height unit in a<br />

space-saving manner and thus enable stepby-step<br />

expansion: simply cost-effective.<br />

For perfect order in the rack, the cables are<br />

routed away in a space-saving and tidy way,<br />

both at the front and at the back. Wiring is<br />

not necessary. Pre-terminated trunk cables<br />

ensure quick commissioning and maximum<br />

ease of handling. Thanks to their snap lock,<br />

the pre-terminated modules can be installed<br />

safely in seconds in just a few steps without<br />

any special tools. Despite the snap function,<br />

ground bonding is guaranteed at all times.<br />

The 25-year system and 5-year product warranty<br />

also applies to the new 2U 4U housing.<br />

The New FM45 EL –<br />

Stable and Ingeniously Simple<br />

030.8275<br />

With the intuitive FM45 connectors from R&M, installers can<br />

quickly and flexibly change, replace or install cabling in the field.<br />

Now there’s a new family member in metal housing.<br />

Whether for traditional premises wiring<br />

in office buildings, for residential cabling,<br />

in data centers or in industry: The range<br />

of FM45s has been tried and tested for<br />

almost 20 years. The connectors serve as<br />

practical helpers for the construction of LAN<br />

infrastructures, for service, maintenance and<br />

repairs. The FM45 range offers universal<br />

connection solutions for all requirements –<br />

both indoors and out. And now the FM45<br />

family is growing again: The completely newly<br />

developed FM45 EL Cat. 6 A<br />

in a robust<br />

design with die-cast zinc housing is suitable<br />

not only for traditional LAN cabling, but also<br />

for industrial environments and the IoT. It<br />

ensures stable data transmission, even under<br />

the most adverse circumstances. Thanks to<br />

the extended temperature range of -40 to<br />

85°C, it can withstand many influences. The<br />

connector can be rewired. With its insulation<br />

displacement connections (IDC), it is also<br />

ideally suited for PoE applications. It bears<br />

the R&M PowerSafe quality seal.<br />

Effortless wiring<br />

Depending on the installation environment,<br />

two straight and two angled versions are<br />

available, each in Cat. 6 A<br />

, for cable diameters<br />

of 5—7 mm or alternatively 7—9 mm. Smart:<br />

The wiring method is the same – and child’s<br />

play. Regardless of whether the connector is<br />

used for new buildings or conversions, the<br />

wiring is always successful, even without<br />

special tools. It can be taken care of with<br />

stranded or straight wire from AWG22 to<br />

AWG26, regardless of whether shielded<br />

or unshielded cables are used. Easy-to-read<br />

color markings provide additional support.<br />

A handle guard is helpful when removing<br />

the connector in hard-to-reach areas. It can<br />

be shortened or removed completely. Two<br />

differently colored clamping rings in the<br />

nut ensure reliable strain relief and the<br />

selection of the correct diameter. The<br />

connector is only 46 mm long and therefore<br />

also ideal for applications in confined spaces.<br />

It is also backwards compatible and guar-<br />

anteed to be reliable: R&M offers a 5-year<br />

product warranty and a 25-year system<br />

warranty.<br />

The new FM45 EL from R&M will be available<br />

in summer 2023.<br />

Sustainable Investment in<br />

Global Value Creation<br />

R&M is consistently developing into a global provider of complete and<br />

integrated infrastructure solutions with an international supply chain and its<br />

own competence centers.<br />

Comprehensive support for customers when<br />

it comes to planning, building and managing<br />

networks – this is part of R&M’s mission. The<br />

momentum of the digital era calls for holistic<br />

approaches. This is why R&M is continuously<br />

transforming itself from a component<br />

manufacturer to a provider of complete<br />

and integrated infrastructure solutions for<br />

data and communications networks. Today,<br />

R&M is a global consultant and supplier for<br />

data center infrastructures, local networks,<br />

smart buildings and the telecommunications<br />

industry.<br />

By continuously investing in its 14 plants,<br />

R&M is reinforcing its strategy and is increasingly<br />

relying on dedicated competence<br />

centers, such as the new rack and cabinet<br />

plants in Italy for the EMEA region and in<br />

China for the APAC region, as well as FO<br />

cable production in the Czech Republic. In<br />

recent months, their machinery has been<br />

significantly expanded and modernized.<br />

Bundled supply chain<br />

The R&M plants are part of a centrally<br />

controlled production network that has<br />

passed all the stress tests even in times of<br />

crisis and remained able to deliver. During<br />

the pandemic, a new fiber optic production<br />

facility in Pinghu, China, was set up remotely<br />

in accordance with Swiss quality standards,<br />

meeting all the required ISO certifications.<br />

At the beginning of 2023, the machinery for cabinet production at R&M Tecnosteel in Brunello<br />

was expanded to include a laser cutting machine with fully automatic loading and pallet changing for<br />

operator-free processing.<br />

With its supply chain, R&M achieves a depth<br />

of value creation and independence that<br />

stands out across the industry. For customers,<br />

especially providers of data centers, R&M can<br />

efficiently merge all necessary infrastructure<br />

components and offer them as an all-in-one<br />

solution. And that means: connectivity,<br />

equipment for cubes and computer halls,<br />

and DCIM solutions for asset, capacity and<br />

change management. The portfolio is rounded<br />

off with solutions for cooling and power<br />

supply. R&M also integrates complementary<br />

products from proven partners in the industry.<br />

This «all-inclusive» approach significantly<br />

reduces the burden on customers as they<br />

don’t have to worry as much about the details<br />

of communication infrastructure projects.<br />

The local R&M consulting and sales team<br />

accompanies and advises business partners<br />

from the start of the planning phase.<br />

Corporate<br />

More than<br />

Customer<br />

Orientation<br />

050.7328<br />

When R&M founded its first foreign subsidiary in Germany in 1982, the company was<br />

already demonstrating three compelling qualities: The ability to quickly familiarize itself<br />

with local conditions, direct involvement on site and high standing.<br />

These qualities represent a holistic understanding<br />

of customer orientation. R&M has<br />

always stuck to that, even in very challenging<br />

times. Local R&M organizations and key<br />

partners can supply goods anywhere in the<br />

world at any time.<br />

Following the initial expansion abroad, the<br />

company quickly entered other European<br />

countries, Asia, North and South America,<br />

as well as the Middle East. R&M experts<br />

are now working locally in 40 countries. In<br />

addition, there are 14 manufacturing facilities<br />

in leading economic zones.<br />

Accessible on site<br />

R&M consultants support project partners<br />

directly on site, often from the initial planning<br />

stage through to training sessions for<br />

installers. As residents, they know the local<br />

conditions. With their high level of expertise,<br />

they are able to respond optimally to<br />

customer needs and design specific system<br />

solutions. Short-term customization is also<br />

possible. Local product managers are available<br />

for this purpose. Spacious showrooms at<br />

the local R&M Representatives' showcase the<br />

potential solutions on site.<br />

With its regionally oriented, self-controlled<br />

production and distribution infrastructure,<br />

R&M works quickly, flexibly and independently.<br />

Products in daily demand are available<br />

close to the customer from the warehouse<br />

thanks to predictive distribution.<br />

The just-in-time deliveries of assembled,<br />

factory-tested, ready-to-install systems take<br />

place over comparatively short transport<br />

routes, which concurrently means less fuel<br />

consumption and fewer greenhouse gases.<br />

The company’s 14 own manufacturing facilities<br />

and their warehouses are strategically<br />

positioned, true to the principle: Production<br />

in the region for the region. They work in accordance<br />

with the demanding Swiss concept<br />

of quality. Our customers can rely on this.<br />

Distributing Power<br />

Intelligently<br />

Intelligent power distribution units from R&M offer decisive advantages<br />

when it comes to monitoring energy distribution and consumption, flexibility<br />

and response speed in data centers and server rooms.<br />

It all starts with the power supply. Suitable<br />

power distribution units are required to<br />

ensure power distribution and keep an<br />

eye on consumption. Ideally smart ones.<br />

These PDUs (Power Distribution Units) can<br />

be used to switch or administer slots individually.<br />

To this end, R&M has included<br />

the new ActiPower 4.0 rack power distribution<br />

units in its program as it meets the<br />

requirements of data centers and server<br />

rooms. Attractive: This is a complete PDU<br />

range with accessories, which is available as<br />

an all-in-one solution from a single source<br />

(«one-stop shop»). R&M presents three variants<br />

to ensure that the power distribution<br />

units suit the respective demand exactly.<br />

More than just distributing current<br />

1. The ActiPower 4.0 Basic in an ultralight<br />

aluminum housing offers various mounting<br />

options as well as low hydraulic-magnetic<br />

overcurrent fuses. The state-of-the-art IEX<br />

(C13/C19) combination connector socket<br />

with locking system for P-Lock and V-Lock<br />

connectors makes the PDU versatile and<br />

allows any combination of C14 and C20<br />

connectors to be connected.<br />

2. The ActiPower 4.0 Monitored also features<br />

a communication card with two Gigabit<br />

Ethernet connections for third-party access<br />

to the PDU as well as an SNMP interface.<br />

The card can be replaced during operation.<br />

In addition, the input power per phase (V, A,<br />

Hz, W, VA) is measured.<br />

3. The ActiPower 4.0 Managed is structured<br />

like the Monitored version, but can also<br />

measure and switch the connector sockets.<br />

All power distribution units consist of<br />

high-temperature components and are<br />

configured for reliable operation up to an<br />

ambient air temperature of 60°C. They<br />

can be mounted without tools<br />

in the R&M BladeShelter rack.<br />

Temperature and humidity sensors,<br />

door contact sensors and water<br />

detection sensors are available<br />

as accessories. Last but not least,<br />

the components are integrated<br />

into the inteliPhy net software for<br />

automated infrastructure, capacity<br />

and asset management.<br />

Double Anniversary in<br />

Northeast Europe<br />

30 Years in Poland – 25 Years in Hungary<br />

Economic development in Eastern Europe since 1990 can be attributed primarily to the<br />

motivation of the people. And this is something R&M is feeling too. The R&M team in Poland<br />

has been writing an exemplary success story for 30 years; the team in Hungary for 25 years.<br />

050.7329 050.7330<br />

It began with the modernization and boom of<br />

public telephone networks in the 1990s. The<br />

Eastern European telecommunications sector<br />

launched an investment program of historic<br />

proportions once the countries had opened<br />

up to the free market.<br />

R&M got involved at an early stage and<br />

networked with open-minded, highly motivated<br />

specialists from the industry. Together<br />

with sales partners and system integrators,<br />

R&M quickly established itself as a provider<br />

of assembly-friendly distribution solutions.<br />

The quality and ease of handling of the VS<br />

modular main distributors are legendary.<br />

In 1993, R&M founded its first Eastern<br />

European sales office in a rented office in<br />

Warsaw – an office still run today by Managing<br />

Director Andrzej Zagólski. At the same time,<br />

R&M established itself as the market leader in<br />

the telecommunications industry in Hungary.<br />

Its success was based on its role as a pioneer<br />

in ADSL/VDSL broadband technology. Tamás<br />

Getta’s young team built up first-class customer<br />

relationships, resulting in the founding<br />

of R&M Hungary in November 1998.<br />

Success in the LAN market<br />

The second wave of success came with the<br />

entry into the LAN market around the turn of<br />

the millennium. R&M provided leading-edge<br />

Ethernet cabling solutions, the universal Cat.<br />

5 connector format and high-end fiber optic<br />

connectors. The accession of Eastern European<br />

countries to the EU boosted the market.<br />

R&M equipped the Nokia plant, which at the<br />

time manufactured 300,000 mobile phones<br />

a day, with structured cabling systems. R&M<br />

also supplied the network solution for a pioneering<br />

FTTH project in a luxury residential<br />

park near Budapest.<br />

Copper competence center<br />

The Polish subsidiary became a logistics<br />

center for the Northeast Europe region.<br />

From 2000 onwards, Reichle & De-Massari<br />

Polska Sp. z o.o. began manufacturing copper<br />

products for the R&M Group and became the<br />

R&M copper competence center. A further<br />

important step followed in 2013 with the<br />

division into two companies for sales and<br />

production.<br />

One of the most important reference projects<br />

was the network installation in Rondo1, a<br />

sensational office high-rise in downtown<br />

Warsaw. The office cabling with the extended<br />

office cabling system developed by R&M enabled<br />

completely flexible use of the premises.<br />

This was followed by orders from the state,<br />

Polish air safety and real estate investors, such<br />

as the majestic Europejski Hotel in Warsaw.<br />
