The Vision<br />

that has Connected Us<br />

for Almost 60 Years<br />

050.7360<br />

Dear Business Partners<br />

Enabling communication through optimal<br />

network infrastructures – that was already<br />

the aim of Hans Reichle and Renato De-Massari<br />

when they developed a revolutionary<br />

telephone outlet almost 60 years ago. Our<br />

mission is still the same, but when it comes to<br />

technology everything has changed.<br />

Today, we are amazed that artificial intelligence<br />

(AI) can, for example, paint pictures,<br />

write essays and diagnose medical conditions.<br />

Machines now perform the brainwork that<br />

was previously considered a human domain.<br />

However, these high-performance computers<br />

only run if their network infrastructures can<br />

be relied upon. No AI without connectivity.<br />

Megatrends such as AI are also driving the<br />

boom in data centers. If you want to hold<br />

your own in this market, you have to be able<br />

to move at a fast pace: Latencies and data<br />

transfer rates are constantly accelerating.<br />

At the same time, data centers should be<br />

improving their energy efficiency and working<br />

trouble-free at all times. In our FOCUS story,<br />

we take you on a journey through time in the<br />

data center and show you how we can help<br />

you plan and operate.<br />

With our complete portfolio for data center<br />

infrastructures, we have also specialized<br />

in continuously improving efficiency and<br />

security. With the BladeShelter T7 PLUS<br />

rack system, for example, which has a static<br />

load-bearing capacity of 1,800 kg and separates<br />

the flow of hot and cold air, power<br />

consumption is noticeably reduced. And the<br />

smart ActiPower 4.0 Power Distribution Unit<br />

(PDU) can monitor environmental parameters<br />

such as energy consumption, temperature,<br />

humidity and access security.<br />

Staying on the ball<br />

The further modernization of our product<br />

range and our own infrastructures has traditionally<br />

been a very high priority at R&M. This<br />

is why, whenever possible, we report at an<br />

early stage on the innovations of tomorrow,<br />

their implementation in our solutions and<br />

our modernization efforts. You will also find<br />

relevant articles in this latest issue of our<br />

specialist magazine <strong>CONNECTIONS</strong>.<br />

As a full-range provider as well as a provider<br />

of individual, custom-made solutions and<br />

with many market organizations and plants<br />

around the world, we are always close to<br />

our valued customers – in order to optimize<br />

network infrastructures together.<br />

We wish you an inspiring read.<br />

Time Travel<br />

through the Data Center<br />

050.7361<br />

Take a trip to the future through your data center! You will be starting out in 2023<br />

and will see how the computer room will change over the next ten years. You are likely to<br />

meet a few surprises on the way. Read on to find out what is already on the cards today<br />

and what you need to take with you for a secure future.<br />

Aside from growing data traffic and ever<br />

faster machines: Who can even guess at<br />

what the data center will have to take care<br />

of in the future? A journey through time could<br />

provide creative support for planning the<br />

future. There will be new insights along the<br />

way. This would be a fantastic way of getting<br />

to know the needs of the market and new<br />

customer projects ahead of time.<br />

Many a migration and scaling project<br />

becomes a cost pit along the way. Plug &<br />

Play, fast-moving servers and high-speed<br />

switches are clearly not enough to master<br />

the future. The capacity offered by the IT<br />

infrastructure (non-compute layer) must be<br />

able to «breathe» in future.<br />

Megatrend of digitalization<br />

Back to the present. What can operators<br />

already expect today? Experience shows that<br />

the market does not allow data centers to take<br />

a break. Today, heavy duty is the order of the<br />

day: Cloud, edge, hybridization, «everything<br />

as a service», gaming, streaming, blockchain,<br />

5G and the AI revolution – digitalization has<br />

many drivers, some of which support or even<br />

reinforce each other. This certainly gives you<br />

a rough idea of the trip to the future.<br />

Every day, unstoppable digitalization demands<br />

new and more powerful IT equipment,<br />

shorter latencies and higher transmission<br />

rates. Over the past three years, the workload<br />

has in some cases approached the physical<br />

limit. At the same time, data centers should<br />

be resilient and available at all times without<br />

interruption, which requires expensive redundancy.<br />

In addition, they should be increasingly<br />

efficient in their production, with ever better<br />

PUE (Power Usage Effectiveness) and higher<br />

ROI (Return on Investment).<br />

These laws and requirements have been in<br />

place for a long time and will accompany data<br />

centers into the future.<br />

There is a new aspect that will occupy data<br />

center providers even more intensively in<br />

the future: They urgently need to address<br />

Forecasts about the development of the Data Center market<br />

the issues of carbon footprint, decarbonization<br />

and power supply. These questions<br />

have to be asked at all levels, from premises<br />

and buildings to computer rooms and even<br />

high-performance chips. In particular, data<br />

center operators will be faced with new underlying<br />

conditions in the form of extended<br />

state norms and adapted industry standards<br />

for data centers, the call for the recycling of<br />

used raw materials, waste heat utilization<br />

concepts for the surrounding buildings and<br />

residents, and also increasingly the use of<br />

renewable energy sources.<br />

Spontaneous, fast, complex<br />

Data center customers are having to act faster<br />

and faster. Business models are adapted<br />

or scaled. Digitalization gives companies the<br />

opportunity to implement many things in a<br />

short space of time. For security or competitive<br />

reasons, they often release services, apps<br />

and updates at short notice. Applications for<br />

masses of end users, or complex applications<br />

with a high workload for the servers are on<br />

the agenda.<br />

Data centers must therefore be responsive.<br />

And they have to be able to provide scalable<br />

infrastructures tailored to the customer<br />

and project at short notice. Together with<br />

customers, operators are making complex<br />

decisions more often than ever before.<br />

Understanding new customer applications<br />

leads to an adapted conversion into new IT<br />

equipment (such as servers and storage) and<br />

its networking with corresponding switches.<br />

If this equipment is to be integrated into an<br />

efficient environment and perhaps even into<br />

a partially existing infrastructure, there is more<br />

to be done than just filling up free spaces in<br />

existing IT cabinets. The increasing demand<br />

for efficiency in the data center requires the<br />

coordination of all sections of the infrastructure<br />

in order to optimize the critical interaction<br />

between compute and non-compute layers.<br />

Would anyone have thought of this recently<br />

with conventional planning focused on individual<br />

sections? All plans have to be adjusted<br />

to one another, and stand-alone solutions will<br />

no longer meet the targets set in the future.<br />

What that means for cooling<br />

The challenges associated with cooling are<br />

impressive. When the computer room was<br />

first set up, all the amenities were perfectly<br />

adjusted to each other: Cold aisles and hot<br />

50 %<br />

increase in the electrical footprint<br />

of all data centers by 2025<br />

500 %<br />

growth of globally generated<br />

data by 2025<br />

Source: Schneider Electric<br />

aisles, air flow, fans and cooling systems,<br />

operating temperature of IT equipment, etc.<br />

Servers with larger computing capacity are<br />

now entering the computer room because<br />

customers want to launch new, powerful digital<br />

products. Suddenly something changes<br />

as regards cooling. Fans are operating at full<br />

speed on a permanent basis and consuming<br />

more power. The cause has to be investigated,<br />

and that no doubt means maintenance work,<br />

in the worst case operational interruptions<br />

and subsequent renovation work. Cable<br />

bundles have to be laid differently so that<br />

the air can flow optimally again.<br />

If installations are equipped at maximum<br />

capacity at the beginning of expansion, this<br />

can lead to inefficiencies and even damage<br />

to the system. Here, a simple example: A rack<br />

was initially equipped with two blades, which<br />

together had an output of 2 kW. But the cooling<br />

system has already been configured for 20<br />

kW or for fully equipped rack rows. Excessive<br />

cooling changes the dew point. Moisture<br />

accumulates. Certain systems stop when<br />

there is too much cold or the cooling system<br />

runs at a level that is too low, resulting in a<br />

constant switching on and off. This can lead to<br />

complete cooling system failure prematurely.<br />

Some data centers take precautions by<br />

proactively planning in headroom. In doing<br />

so, they have to remember that cooling and<br />

power supply must be adjusted to both the<br />

reduced and the full IT load.<br />

One possible solution for this would be<br />

decentralized, modular inline and side cooling<br />

units such as the BladeCooling units from<br />

R&M Tecnosteel. They can be dimensioned<br />

according to the respective computing<br />

performance.<br />

24 %<br />

of Executives report that over 50 %<br />

of their data centers will configure<br />

themselves by 2025<br />

75 %<br />

of data will be processed in<br />

edge data centers<br />

Here, too, an interdependency would have<br />

to be considered: The energy and space<br />

requirements of the inline and side cooling<br />

units must be taken into account when planning<br />

the expansion. Once again, IT equipment<br />

and operating temperatures, ventilators,<br />

cooling system, containment and air routing<br />

have to be coordinated with one another.<br />

Focus<br />

The journey to 800 Gigabit<br />

The new digital applications will also generate<br />

higher data volume in the future. In order to<br />

be able to serve these applications under the<br />

additional constraint of latency requirements<br />

in the data center, the migration to 400<br />

Gigabit, 800 Gigabit and 1.6 Tb Ethernet is<br />

necessary. Are those responsible aware of all<br />

the interdependencies? It’s about more than<br />

just highly scaled connectivity in a spine-leaf<br />

architecture.<br />

The space provided for cabling in a rack is<br />

limited and is difficult to expand after initial<br />

installation. Cabling with MPO connectivity<br />

and the HD connectors (e.g. SN) could make<br />

maximum use of the space thanks to high<br />

connection density.<br />

Three steps<br />

Despite the many unknowns, the increasing<br />

multidimensional correlations in the data<br />

center can be controlled. When a customer<br />

project is pending, three main steps are<br />

recommended:<br />

1. First of all, the client’s objectives and business<br />

case must be understood. Specify<br />

precisely which applications and services<br />

are planned.<br />

2. Analyze which computing and transmission<br />

services, technologies, functions are<br />

required.<br />

3. This information is essential for designing<br />

or adapting the non-compute infrastructure<br />

needed to keep the IT systems<br />

running.<br />

As a trusted advisor, R&M supports such<br />

processes with a holistic approach and a<br />

view from a non-compute perspective.<br />

At the beginning of the project, R&M can<br />

describe interdependencies, gaps, time<br />

requirements, migration and scaling options.<br />

Suitable power supply, cooling, cabling, and<br />

suitable racks, panels and enclosures can be<br />

reliably determined as can the underlying<br />

conditions for installation, operation, maintenance<br />

and quality assurance.<br />

As a provider of integrated infrastructure<br />

solutions, R&M provides a future-oriented<br />

portfolio for data centers. It ranges from<br />

connectivity to DCIM software. This enables<br />

R&M to supply individual modules and complete<br />

infrastructures for computer rooms<br />

which are ready for installation from a single<br />

source, as well as retrofit and scale them.<br />

R&M supports data centers from analyzing<br />

and planning to implementing and managing<br />

infrastructures.<br />

more sophisticated the integration, the more<br />

successfully data centers will be able to serve<br />

the market in the future.<br />

Insight into data center infrastructures with<br />

the DCIM software inteliPhy net<br />

The cabling must be planned for the new<br />

architecture in detail and with foresight. For<br />

the journey to 800 Gigabit and beyond, data<br />

centers need a detailed scaling and migration<br />

strategy. And that strategy has to be about<br />

more than just high density. The interdependencies<br />

between racks, cabling density,<br />

weight, cable pathways, cable management<br />

and airflow also need to be investigated.<br />

The new PDU affects everyone<br />

A current example which will also influence<br />

future planning: Where conventional connector<br />

strips were previously sufficient, remotely<br />

Smart Power Distribution Units:<br />

a cost-saving solution<br />

050.6975 050.7137<br />

The DCIM software inteliPhy net from R&M<br />

enables asset management of IT hardware.<br />

controllable, hydraulically-magnetically<br />

protected PDUs with network modules will<br />

soon be used. They are intended to make<br />

the electrical infrastructure safer and more<br />

intelligent. Once again, it becomes apparent<br />

that a single advance entails a number of<br />

interdependencies.<br />

The infrastructure planners have to accommodate<br />

additional bus cabling and sensors<br />

in the rack. For network planners, it is a<br />

matter of how many ports and IP addresses<br />

the intelligent PDUs take up. Operators and<br />

customer care want to know if changes and<br />

maintenance require expensive interruptions<br />

of operation. The sustainability manager<br />

needs information about power consumption.<br />

The provision of detailed information<br />

for each connected IT device helps to determine<br />

the current, contemporary PUE and<br />

to plan the data center’s energy balance in<br />

the future.<br />

Homework: Digitizing<br />

One prerequisite is that data centers also<br />

digitize their own operations.<br />

They will understand the correlations more<br />

easily if they can fully map operation in<br />

superordinate, multifunctional management<br />

software. This requires deep insight into<br />

the facilities and infrastructures on the<br />

basis of digitized data. In this way, operation<br />

managers can be relieved of their two main<br />

tasks: Planning the status of the installations<br />

of all sections and documenting their current<br />

status as well as ensuring efficient operation.<br />

The software should be able to simulate how<br />

new, additional or changed IT, applications<br />

and services affect operations. It should make<br />

it possible to develop scenarios for spaces,<br />

racks, cabling, power supply, cooling, sensors,<br />

and other gray space elements.<br />

With such a solution, those responsible<br />

could take a «virtual» future journey through<br />

their data center. They could avoid surprises,<br />

gain planning certainty, avoid oversized<br />

investments and bottlenecks, and efficiently<br />

implement customer requests.<br />

070.5066<br />

The ActiPower 4.0 Power Distribution Unit<br />

from R&M is intended to bring about cost- and<br />

energy-saving data center operation.<br />

The smart Power Distribution Unit<br />

ActiPower 4.0 from R&M aims to save<br />

costs and reduce power consumption in<br />

data center operation. The switching relays<br />

of the ActiPower 4.0 consume 70 % less<br />

energy than comparable products. The<br />

PDUs can withstand environmental temperatures<br />

of up to 60° Celsius. They can be<br />

managed remotely via Ethernet ports and<br />

the DCIM program inteliPhy net. They can<br />

communicate with sensors for temperature,<br />

humidity, water, smoke, vibration and<br />

door contacts.<br />

Thinking multidimensionally<br />

All this means that it’s increasingly about more<br />

than just «plug & play» or about uploading<br />

new software. Today, and in the near future,<br />

digitalization projects are deeply affecting<br />

data center processes and infrastructures. The<br />

details and deadlines of individual projects can<br />

often only be determined at short notice.<br />

There is growing recognition that data<br />

centers are increasingly dealing with multidimensional<br />

correlations. Today, it is particularly<br />

important to pay attention to the integration<br />

of non-computing areas. This is crucial in<br />

order to keep the computer room running<br />

efficiently whatever the load.<br />

That’s why it’s important to take a holistic<br />

approach. The better the IT hardware, power<br />

supply, connectivity, cooling and security<br />

solutions interact, the more cost-efficient,<br />

secure and sustainable the overall performance<br />

will be. The more comprehensively<br />

the correlations are understood and the<br />

Success<br />

«R&M means quality and partnership.»<br />

Louis Cruchett, Sr. VP Services, Shields Environmental<br />

Sustainable<br />

in Every Respect<br />

050.7368<br />

Whether in the environmental field or in a business relationship,<br />

sustainability is not always easy to achieve and implement. It requires a<br />

direct approach with constant attention. R&M and Shields Environmental<br />

have established a sustainable partnership based on these principles.<br />

050.7369<br />

Shields Environmental is a global company,<br />

established in 1979, that takes sustainability<br />

seriously, extending the service life of telecom<br />

network equipment. The company offers<br />

repairs, refurbishment, and recycling. Two<br />

years ago, Shields launched their MarketPlace<br />

platform which enables network providers<br />

across the globe to buy and sell network<br />

equipment. It’s an easy way for operators to<br />

join the circular economy, create savings as<br />

well as reach the NetZero targets being set<br />

across the globe. Due to the huge demand<br />

MarketPlace has created, Shields have recently<br />

launched their Vendor Portal platform which<br />

focuses on building sustainable partnerships<br />

to standardize high quality and fast lead times<br />

across the circular economy supply chain.<br />

Service for telecoms<br />

In the U.S., Shields is well known for its EF&I<br />

Services business unit, which supports the<br />

largest telecommunications providers in North<br />

America with a portfolio of services for their<br />

projects. This includes engineering, infrastructure,<br />

primary and secondary power, equipment<br />

installation and connectivity, and test and<br />

turn-up services in the in-building environment<br />

(Central Offices, Hubs, and Cell Sites).<br />

Customers appreciate the high measure of<br />

experience and the industry-leading quality.<br />

As a result, Shields’ Services Division has<br />

experienced tremendous growth since the<br />

division was opened on the West Coast<br />

in October 2016, now providing services<br />

across the U.S. incl. Alaska and Hawaii. The<br />

installation team is one of the most highly<br />

qualified in the industry and has the necessary<br />

infrastructure to be able to continue<br />

this performance at any time. Apart from<br />

identifying new business opportunities, the<br />

most significant obstacle faced by Shields is<br />

the scarcity of skilled technicians and experienced<br />

managers familiar with the quality<br />

standards they require.<br />

have been supported. These include the<br />

first 4G, 5G/Fixed Network, and MEC trial<br />

deployments, as well as on-site Command<br />

Center networks necessary for hosting a<br />

Super Bowl for Tier 1 Service Providers.<br />

Market need identified<br />

The partnership resulted in an intense<br />

sales relationship. Shields and R&M jointly<br />

developed new products, including the<br />

1.2 mm patch cord. Both companies had<br />

listened carefully to customers and realized<br />

that there was a demand for thinner patch<br />

cords. There is only a limited supply available<br />

on the market. As part of the distribution<br />

partnership, the R&M production network<br />

has been supplying thin patch cords since<br />

2021. Shields introduced it to the market<br />

with immense success. Further new developments<br />

are currently being planned.<br />

Shields’ delivery and installation program<br />

includes fiber optic cabling and connectivity.<br />

The components are each part of a project.<br />

That’s why they must fit perfectly with the<br />

company’s quality standards.<br />

050.7370<br />

Shields used cabling solutions from R&M to<br />

build data networks for hosting the Super Bowl.<br />

R&M is the preferred cabling supplier across<br />

the U.S. Shields and R&M support construction<br />

projects such as campus networks and<br />

PoP stations. In the mobile/WiFi market, for<br />

example, projects in the areas of Central<br />

Offices, iEN (C-RAN, 5G, MEC), and DAS<br />

Takes SPE Forward<br />

R&M is the first manufacturer to offer a complete SPE<br />

cabling system in accordance with IEC 63171-1.<br />

The market launch started at the end of 2022. Now we are<br />

continuing with the launch of the first SPE transmission<br />

system. Its range: at least 600 meters.<br />

Single Pair Ethernet (SPE) still needs a little<br />

boost. R&M has teamed up with the active<br />

device manufacturer Zemfyre from Canada<br />

to bring momentum to the wide SPE application<br />

market.<br />

Together, the two companies have specified<br />

an initial SPE transmission system with active<br />

equipment. With a switch and media converter,<br />

it enables data transmission of up to<br />

10 Mbit/s over at least 600 meters. The idea<br />

is to go beyond the traditional LAN distance<br />

of 100 meters with SPE. This makes the SPE<br />

transmission system suitable for networking<br />

remote applications and locations.<br />

RJ45 connection, with the media converters<br />

requiring a local power supply.<br />

The new approach is to connect the applications<br />

using Single Pair Ethernet. In this way,<br />

the applications can be used directly with<br />

the LAN and the cloud. The R&M solution<br />

assumes that the applications do not require<br />

any particularly high data rates.<br />

As long as no SPE terminal equipment is<br />

installed on site, this concept also works with<br />

media converters. They mediate between<br />

SPE and the RJ45 connections of conventional<br />

terminal equipment.<br />

over Ethernet (SPoE). This solution requires<br />

less space on site than the FO model and is<br />

more reliable because the power is supplied<br />

centrally. Once SPE terminal equipment is<br />

available in the future, the media converters<br />

will no longer be necessary. The devices can<br />

Initial feedback from the market confirmed<br />

The R&M HEC connectors work reliably in any extreme environment, for example in freeway tunnels, satellite dishes or wind turbines.<br />

This is Where<br />

HEC-BR and HEC-QR Work<br />

The new outdoor connectors from R&M won’t have to look hard to find a place to work.<br />

They will be in demand in all kinds of places – for example at the next corner end.<br />

Telecom companies are currently connecting<br />

entire cities, countries, transport routes and<br />

locations with 5G small cells. 5G antennas<br />

are installed every few hundred meters. They<br />

buildings have to withstand all weathers. At<br />

the same time, they also have to be easy to<br />

operate in any situation.<br />

This is why R&M has designed the robust<br />

HEC pair in such a way that the housing<br />

can be mated by someone without a direct<br />

view who is wearing gloves and working<br />

one-handed. The end faces of the fibers<br />

cannot be soiled or scratched.<br />

HEC stands for Harsh Environment Connector.<br />

The two connector variants from R&M<br />

will work reliably in any extreme environment.<br />

Areas of application include wind and solar<br />

parks, which are constantly subjected to the<br />

weather. The alternative power plants require<br />

stable fiber optic connections to data networks<br />

so that information about the available<br />

power can be accessed in real time.<br />

Wide range of applications<br />

Operators of roads, tunnels and railway lines<br />

are also making increasing use of fiber optic<br />

cabling. Their infrastructures are perfect for<br />

expanding data lines. The cables, enclosures<br />

and connectors are also exposed to significant<br />

environmental impacts: moisture, salt<br />

mist, dust, vibrations. This is exactly where<br />

HEC-BR and HEC-QR come into their own.<br />

At events, large volumes of data and<br />

high-resolution live streams are produced<br />

for the Internet. Fiber optic cables are the<br />

ideal transport medium. When setting up and<br />

dismantling events, cables and connectors<br />

are exposed to considerable mechanical<br />

loads. No problem for HEC-BR and HEC-QR!<br />

Other similar areas where they can be put to<br />

good use include mining, oil fields, industrial<br />

facilities, container ports, as well as research<br />

and satellite stations.<br />

When laying above-ground cables for the<br />

FTTH supply, it is often a matter of also being<br />

able to install unusual connections as simply<br />

and cost-effectively as possible. Aerial solutions<br />

from R&M can be used here – including<br />

Vital Signs<br />

under Control<br />

050.7377<br />

Data centers are a prerequisite for digitalization and have a major impact on<br />

economic development. To ensure that they always function smoothly, it is<br />

essential to measure the ambient conditions correctly with the right sensors.<br />

A key component is the intelligent PDU.<br />

The sensors make it possible to monitor various<br />

parameters, such as energy consumption,<br />

temperature, humidity and access security.<br />

This enables administrators to identify potential<br />

problems and take appropriate corrective<br />

measures at an early stage. The intelligent<br />

ActiPower 4.0 Power Distribution Unit (PDU)<br />

Intelligent ActiPower 4.0 PDU from R&M<br />

050.7378<br />

from R&M offers efficient integration. The<br />

connection to the network means that all<br />

sensor data can be displayed and monitored<br />

on the web interface.<br />

Real-time monitoring of energy consumption<br />

is of fundamental importance when it comes<br />

to planning how the racks are to be equipped<br />

with servers. This is because overloading the<br />

power line can lead to significant problems<br />

and, for example, cause failures or safety<br />

risks. This is why measuring the energy consumption<br />

in each rack using smart PDUs has<br />

become established in the industry. Critical<br />

threshold values can be detected and alarms<br />

triggered if need be. This may be the case, for<br />

example, when a rack is expanded to include<br />

additional active servers.<br />

Indispensable for safe operation<br />

Servers not only need sufficient power but<br />

also an optimum operating temperature and<br />

humidity to be able to work efficiently. This<br />

is where temperature sensors such as the<br />

EMD31 come into play. These sensors record<br />

environmental temperature and humidity at<br />

specific points and are connected to the<br />

sensor socket of the ActiPower 4.0 PDU via<br />

an RJ45 cable.<br />

For added security and control, the EMD31<br />

sensor allows the connection of two additional<br />

digital sensors. For example, a moisture<br />

sensor cable can be laid in the floor/raised<br />

floor in order to detect water leaks from cooling<br />

units in good time and prevent potential<br />

damage to the infrastructure.<br />

The security of the data center also plays<br />

a prominent role and access to sensitive<br />

areas must be strictly controlled. Among<br />

other things, door contact sensors are used<br />

to ensure that the lockable rack doors are<br />

properly closed after access.<br />

Liquid Cooling:<br />

Worth Considering<br />

050.7379<br />

Can liquids cool data centers a thousand times more efficiently than air? Or is this<br />

just an exaggerated, general advertising statement from innovative manufacturers?<br />

The range is probably between 50 and 1,000 times more efficient. This article<br />

focuses on what data center providers should consider before investing.<br />

Data centers are increasingly compacting<br />

performance in computer rooms. Servers,<br />

switches and microelectronics are becoming<br />

ever more tightly packed. As processing<br />

power increases, so does the operating<br />

temperature in the racks.<br />

This is why heat dissipation management is<br />

given top priority. Cooling with liquids is basically<br />

much more efficient than conventional<br />

cooling with air. Due to their heat capacity<br />

and density, liquids dissipate heat around<br />

1,000 times more efficiently than air.<br />

Smaller PUE value feasible<br />

Air cooling is established and widespread.<br />

In a conventional computer room layout,<br />

cool air from the cold aisle is blown through<br />

the racks into the hot aisle where the air is<br />

collected. Ventilation ducts and blowers lead<br />

it to cooling units or other heat dissipation<br />

systems.<br />

This classic configuration is no longer<br />

sufficient today. In addition, it is becoming<br />

practically impossible to achieve a PUE (Power<br />

Usage Efficiency) value that meets climate<br />

targets. Operators must find new ways to<br />

make «green data centers» a reality. What is<br />

more, energy costs and legal regulations are<br />

also necessitating action.<br />

The challenge, then, is to operate systems<br />

with a high and continuous workload in an<br />

even more efficient and cost-effective manner.<br />

Air cooling generally achieves a PUE of<br />

1.35 to 1.69. According to a study by the U.S.<br />

Air Force, that figure can be reduced to 1.03<br />

with liquid cooling systems.<br />

In immersion cooling, individual servers or entire systems are immersed in a dielectric coolant.<br />

050.7380<br />

Types of liquid cooling<br />

Liquid cooling is a generic term for the way<br />

in which heat is dissipated. There are very<br />

different liquid cooling systems, although<br />

there are generally three main types: rear-<br />

More efficiency to be expected<br />

Further advances in microelectronics are<br />

to be expected, with energy efficiency<br />

increasing all the time. Innovations such as<br />

co-packaged optics (CPO) aim to minimize<br />

electrical transmission between chips and<br />

fibers and reduce transmission losses. At the<br />

same time, they can increase the number of<br />

transmission channels. There is no need for<br />

conventional connectors. This means that the<br />

front panels of the devices can be designed<br />

more openly in spite of a higher power density<br />

in order to allow more ventilation.<br />

Pros and cons<br />

There are several factors to consider when<br />

choosing a type of cooling, including the<br />

density of the power to dissipate (power/<br />

rack), computer workloads and packing<br />

density, reconfiguration and patching needs,<br />

infrastructures for heat dissipation.<br />

Conclusion: Greater performance and higher<br />

density in the racks do not necessarily mean<br />

that investments and the effort involved in<br />

heat dissipation increase proportionally. But<br />

the demand for heat dissipation tends to<br />

increase. Liquid-based cooling systems are<br />

therefore worth considering in view of their<br />

improved efficiency.<br />

050.7384<br />

In direct chip cooling, small channels take the<br />

coolant into the active electronic equipment.<br />

side heat exchangers, direct chip cooling and<br />

immersion cooling.<br />

– In the case of heat exchangers on the rear<br />

of the racks (rear door heat exchangers), fans<br />

blow the warm air through a grid of pipes<br />

containing coolant. The liquid absorbs the<br />

heat, is pumped to an external cooling mechanism<br />

and returned to the heat exchanger.<br />

– In direct chip cooling, small channels take<br />

the coolant into the active electronic<br />

equipment. The channels and heat sinks are<br />

arranged above or below the heat-generating<br />

chips. This approach requires additional<br />

air circulation to dissipate the residual heat.<br />

– In immersion cooling, individual servers or<br />

entire systems are immersed in a dielectric<br />

coolant. The liquid circulates and transports<br />

heat away. This is the most efficient form of<br />

cooling.<br />

Of course, every approach has advantages<br />

and disadvantages. As yet, there is no onesize-fits-all<br />

solution.<br />

The total cost of ownership (TCO) of liquid-cooled<br />

systems is likely to be significantly<br />

lower. However, the initial investment is<br />

likely to be higher. The layout and premises<br />

of the data center must be evaluated. Heat<br />

exchangers on the racks are easy to install.<br />

Chip cooling and immersion cooling require<br />

specially configured equipment.<br />

Conventional air cooling is sufficient if the<br />

total power to dissipate is below 20 kW per<br />

rack. If it exceeds this threshold value, R&M<br />

believes that a strategy for liquid cooling<br />

should be taken into consideration.<br />

Classic DC cooling management comes under<br />

ways to make «green data centers» a reality.<br />

necessitating action.<br />

Bespoke Compilation –<br />

Ready for Installation<br />

IT and infrastructure managers need to be increasingly<br />

flexible and achieve higher performance at lower costs –<br />

while also paying attention to sustainable solutions. R&M<br />

has responded by offering a simplified and environmentfriendly<br />

logistics process for the fiber optic distribution<br />

platform Netscale 48.<br />

Selecting the right copper and fiber optic<br />

patch panel is crucial for office and data<br />

center cabling in order to establish an efficient<br />

and reliable communications network.<br />

Another decisive factor is the simplification<br />

of the logistics process. With the Netscale<br />

packaging configurator – Visio or intelPhy –<br />

the finished panel can be ordered directly.<br />

This eliminates the need to select and order<br />

trays, modules or rear-cabling managers<br />

(Netscale) separately, reducing ordering time<br />

and minimizing possible errors.<br />

Efficiently packaged and<br />

quickly installed<br />

The cost and effort involved in packaging are<br />

also significantly reduced. The panel is put<br />

together to suit individual requirements and<br />

packaged as a unit, resulting in a considerably<br />

decreased volume of waste. Instead of using<br />

five to ten boxes for individual components,<br />

only one box is needed for the assembled<br />

panel. This saves costs, protects the environment<br />

and reduces transport volumes. The<br />

effort involved in installation is significantly<br />

simplified and reduced. When the box is<br />

opened, the panel is already fully equipped<br />

and can be installed directly without any additional<br />

components having to be assembled.<br />

No special tools are required to install the<br />

robust Netscale 48 panels, which are delivered<br />

in 1U. A further advantage: Customers<br />

benefit from comprehensive warranties,<br />

offering added security and trust.<br />

BladeShelter –<br />

a Full Composition<br />

Vertical cable manager<br />

Integrated data center solutions improve data center<br />

efficiency, scalability and security, optimize costs, and are<br />

easier to manage. R&M has now brought together the<br />

BladeShelter infrastructure from R&M Tecnosteel with its<br />

cabling solutions.<br />

BladeShelter is a product line from R&M<br />

Tecnosteel, R&M’s latest acquisition, which<br />

was developed for data centers with low<br />

power consumption and high thermal stress.<br />

The modular, scalable racks are based on<br />

the T7 PLUS rack system. It now has a static<br />

load-bearing capacity of 1,800 kg and offers<br />

cold/hot separation. The doors are perforated<br />

and provide 82 % air permeability and<br />

concurrent high mechanical security against<br />

access. To minimize power consumption, the<br />

BladeShelter Cube modular enclosure system<br />

is part of the product family. The scalable<br />

system separates hot air flow from cold air,<br />

thus ensuring maximum energy efficiency.<br />

Perfectly cooled and always in view<br />

BladeShelter Cooling provides modular, scalable<br />

cooling units for cooling the infrastructure.<br />

They are in line with the racks, dissipate heat<br />

at the point of origin and thus achieve optimum<br />

efficiency. Another important element<br />

is the smart ActiPower 4.0 multi-plug, with<br />

which the operator can keep an eye on their<br />

energy consumption and prevent failure due<br />

to line overload.<br />

Perfect cable organization<br />

One of the most important details is the cable<br />

routing. The BladeShelter Runner cabling<br />

solution mounted on the roof of the racks<br />

guides the fiber optic, copper and power cables<br />

into physically separated areas in order to<br />

minimize transmission or mechanical interference.<br />

Last but not least, well-organized cable<br />

management is one of the key factors for the<br />

efficient operation of a data center. To this<br />

end, the latest development R&M has come<br />

up with is vertical cable management for the<br />

rack. The vertical channels are attached to the<br />

horizontal profiles. This leads to efficient use<br />

of space and good air circulation, prevents<br />

tangled cables, enables flexible scalability,<br />

and makes troubleshooting simpler. A solid<br />

basis for further technological developments<br />

in this area.<br />

The digital transformation of Parisian airports is moving<br />

forward. Based on the concept of the smart city, the operator<br />

Groupe ADP is developing the Paris-Charles de Gaulle and<br />

Paris-Orly premises into smart airports. In doing so, ADP<br />

relies on Netscale 48 from R&M as part of the solution.<br />

Groupe ADP’s (Aéroports de Paris) long-term<br />

investment program aims to design mobility<br />

hubs of the future. Innovations for Advanced<br />

Air Mobility (AAM) are constantly being developed<br />

and implemented at the two premises<br />

in Paris-Orly and Paris-Charles de Gaulle.<br />

Terminals and connecting buildings were<br />

recently modernized as part of the framework<br />

of the infrastructure development.<br />

Among other things, Groupe ADP started to<br />

expand its auto bag drop systems last year.<br />

Thanks to digitalization, passengers can check<br />

in their luggage themselves at a total of 460<br />

machines in an average of just 37 seconds.<br />

copper and fiber optic connections in equal<br />

measure.<br />

With Netscale 48, R&M was able to offer the<br />

compelling solution, something confirmed<br />

by Jean-Michel Arondel, Facility and Cabling<br />

Manager, IT technician Arnaud Bonsigne,<br />

and Armando Grilo, Head of the Roissy<br />

Data Center. The project managers from<br />

installation partner BTB Elec. emphasize<br />

the installation convenience of the R&M<br />

products. For BTB Elec., it was important to<br />

be able to carry out the assembly work as<br />

quickly and easily as possible.<br />

The solution for Groupe ADP<br />

For the construction of the data center infrastructures<br />

with more than 180 racks, R&M supplied:<br />

– Patch panels: Netscale 48 for mixed media<br />

distribution<br />

– Connectivity: pre-terminated Cat. 6 A<br />

EL<br />

modules, shielded and LC Duplex<br />

– Patch and trunk cabling: R&M ThinLine<br />

Cat. 6 A<br />

S/FTP, Uniboot LC Duplex and MTP<br />

with OM4 and OS2<br />

- Racks: R&M Tecnosteel cabinets<br />

Netscale 48 meets the expectations of the IT<br />

department for optimized administration of patch<br />

connections for the IT systems. The new network<br />

distributors will support Groupe ADP in rapidly<br />

rolling out additional digital applications for airport<br />

operations.<br />

Netscale 48 integrates copper and fiber optic<br />

connectivity in a single height unit. Despite<br />

the density of the mixed media platform, the<br />

patch cords are easy to operate. Technicians<br />

can unplug and plug in the trunks in just a<br />

few simple steps and thus quickly carry<br />

out changes or maintenance work on the<br />

network.<br />

Connectors for<br />

400G and More<br />

Increasing bandwidth requirements, space problems, the demand for lower<br />

latency as well as availability requirements are just some of the factors driving the<br />

development of the next generation of transmission technology for data centers<br />

forward. The HD connectors from R&M meet these requirements.<br />

050.7317<br />

The name of this next generation of transmission<br />

technologies is: «400G and more».<br />

These technologies enable transmission rates<br />

of 400 Gigabits per second (400G), 800G<br />

and higher – up to 1.6 Terabit Ethernet (1.6T)<br />

networks. The small, multi-fiber connectors<br />

enable higher connection density and more<br />

Connectors for 400G and more<br />

CS (Contiguous Singlemode by Senko)<br />

is suitable for transmission over longer<br />

distances between data centers. Type<br />

QSFP-400G-2FR4 for example, which is<br />

configured for 400 Gigabit Ethernet, is<br />

used as a transceiver.<br />

MDC (Miniature Duplex Connector) is a<br />

two-fiber connector similar to the SN from<br />

USConnec with the same small form factor<br />

for transmission in the data center (single<br />

and multimode).<br />

New plug faces<br />

In order to get the number of fibers into ever<br />

tighter spaces, new plug faces were standardized<br />

and are now ready for integration.<br />

R&M offers the right connectors for these<br />

requirements with future-proof transmission<br />

rates to suit demand. And all in line with<br />

one-stop shopping, as a patch cord, prefabricated<br />

trunk solution or as an all-in-one<br />

Cat. 8.1 Applications<br />

in the LAN<br />

Category 8.1 was originally the fastest short-distance runner. With 40 Gbit/s over the<br />

24-meter range, it represented cost-effective hope for data centers. But it also delivers<br />

real peak performance over the middle distance in buildings.<br />

LAN cabling are increasing. The underlying<br />

is increasingly being used for expanded and<br />

new applications. These applications demand<br />

unusual peak performance from traditional<br />

LAN cabling. Until now, it has been configured<br />

for 10 Gbit/s over 100 meters.<br />

Above all, it is about networking WLAN<br />

access points (WAP) and distributed antenna<br />

systems for 5G DAS. These are sporty, bandwidth-hungry<br />

applications. WiFi 6 WAVE2<br />

and WiFi 7 require bandwidths above 10<br />

Gbit/s. But there are also computing-intensive<br />

applications in research and multimedia<br />

that can benefit from higher bandwidths.<br />

Standard offers a way out<br />

This could be solved elegantly with Cat. 8.1<br />

if it weren’t for the length limit of 24 meters.<br />

However, standardization offers a way out.<br />

The TR11801-9909 defines how Cat. 8.1<br />

cabling can also transfer 25 Gbit/s up to 50<br />

meters. Overall, three length-dependent performance<br />

levels can be presented for a Cat.<br />

8.1 installation: 40 Gbit/s up to 24 meters,<br />

25 Gbit/s up to 50 meters and the classic 10<br />

Gbit/s up to 95 meters (graphic).<br />

What does this mean for practice? Based<br />

on the typical distribution of link lengths,<br />

Cat. 8.1 cabling could make a significant<br />

contribution to increasing the performance<br />

of the LAN. In a typical office infrastructure<br />

with a floor distributor, Cat. 8.1 cabling could<br />

supply around 20 % of workstations with 40<br />

Gbit/s and around 60 % of workstations with<br />

25 Gbit/s within the 24-meter range.<br />

Complete Cat. 8.1 solution<br />

With the Cat. 8.1 system, the R&Mfreenet<br />

program offers an RJ45-compatible solution<br />

for bandwidths of up to 40 Gbit/s.<br />

The complete system comprises connection<br />

modules, patch cords and installation<br />

cables. It passed the GHMT test. The<br />

channel is certified for 40 Gbit/s up to<br />

30 meters, 25 Gbit/s up to 50 meters.<br />

cabling in the LAN can cover the requirements<br />

for future data cabling with maximum<br />

bandwidth and full backward compatibility.<br />

Variable speed zones in the LAN with Cat. 8.1<br />

(Graphic: R&M)<br />

In modern buildings, redundant floor distributors<br />

are often installed, with correspondingly<br />

shorter transmission lengths. Under this<br />

concept, the Cat. 8.1 infrastructure could<br />

serve more than 50 % of workstations with<br />

40 Gbit/s and all others with 25 Gbit/s.<br />

This is true excellence as it is expected today<br />

and tomorrow. With suitable planning, Cat. 8.1<br />

No saturation signal "OK"<br />

Sales of PoE devices are increasing by 20 % per year. These devices are inevitably<br />

connected to the existing LAN cabling. Users rarely install new PoE-compatible cabling.<br />

This gives rise to significant risks.<br />

Unrecognized weaknesses are often hidden<br />

in low-quality LAN environments. However,<br />

they are relentless when users deploy more<br />

PoE-powered devices. The background is<br />

easy to understand: Thanks to Ethernet, data<br />

signals usually find their way to their destination.<br />

In the event of transmission problems,<br />

the system simply switches back to a slower,<br />

less demanding transmission. The sources<br />

Security through IDC<br />

R&M recommends the use of patch cords<br />

with IDC wiring (insulation displacement<br />

contact) especially for PoE applications.<br />

With IDC, insulation displacement contacts<br />

ensure consistently stable and lowresistance<br />

contacting of the conductor. As<br />

a rule, no resistance unbalance occurs over<br />

the lifespan of the patch cord. No one has<br />

to look for hidden causes of transmission<br />

interference years after installation.<br />

All R&M patch cords with the PowerSafe<br />

quality seal are wired using IDC and are<br />

suitable for Power over Ethernet. When<br />

PowerSafe components are used, R&M<br />

provides a lifetime application warranty<br />

for PoE.<br />

www.rdm.com/<br />

overcoming-resistanceunbalance/<br />

of interference – e.g. excessive resistance in<br />

contacts – remain hidden at first.<br />

A little-noticed parameter can quickly reveal<br />

problems with PoE support: resistance<br />

unbalance within wire pairs (DC Resistance<br />

Unbalance, DCRU). With the same currents<br />

on both conductors, the magnetic flux in<br />

the ferrite core of the input transformers of<br />

the transmitter/receiver unit of the active<br />

devices cancels out with PoE. The data is<br />

transferred without hindrance.<br />

If the two conductors have different resistances,<br />

the current is distributed unevenly<br />

between them. The magnetic flux in the<br />

transformer core will then no longer cancel<br />

out. The DC current can lead to a magnetic<br />

saturation of the transformer, which interrupts<br />

the data transmission. According to<br />

IEEE, even DCRU values of 3 % can lead to<br />

problems with data transmission.<br />

Piercing as a risk factor<br />

Patch cords with piercing wiring often<br />

exhibit this resistance unbalance, something<br />

demonstrated by research carried out by<br />

R&M. The reason is that piercing contacts<br />

age rapidly due to environmental factors or<br />

mechanical loads. The contact resistance of<br />

the two conductors increases over time and<br />

usually increases differently.<br />

This is how the resistance unbalance develops<br />

and grows. It can lead to seemingly<br />

mysterious interruptions in the LAN – a<br />

nightmare for service technicians when it<br />

comes to fault tracking.<br />

Depending on the quality of the piercing<br />

contacts, DCRU values which prevent PoE<br />

transmission may also occur with new patch<br />

cords. That’s why it’s always worth measuring<br />

the entire channel, including the patch cords<br />

used.<br />

In a new white paper, R&M explains more<br />

background on the problem of resistance<br />

unbalance. It is available free of charge on<br />

the website.<br />

Setting up<br />

Customized LAN Racks<br />

030.8522<br />

Whether in small offices or large data centers, LAN racks are an ideal solution for<br />

mounting and organizing network devices. Their modularity makes it easy to adapt to<br />

changing requirements and ensures that the available space is used efficiently.<br />

The new, modular R&Mfreenet rack system<br />

consists of the three modules Classic Line<br />

(CL), Expert Line (EL) and Superior Line (SL).<br />

The basis is a newly developed rack base<br />

frame. Floor and roof elements are inserted<br />

into the four vertical profiles and screwed together,<br />

resulting in an extremely stable frame<br />

construction. The benefit for the customer:<br />

The distributor frame and rack are available<br />

as flat packs that are assembled on site. The<br />

base frame is provided with four 19" galvanized<br />

conductive profiles with height ratings,<br />

and an earthing pin and earthing points for<br />

each cover piece in the floor plate. Roof and<br />

floor are prepared to accommodate 2U cable<br />

entries with brush strips left, right and rear.<br />

Accurate ventilation is also ensured: A further<br />

three openings in the middle can be equipped<br />

with 2- or 4-way fans.<br />

Three product lines available<br />

Freenet Classic Line (CL): The CL cabling rack<br />

is configured for 800 kg payload weight, in<br />

the sizes 800 x 800 mm or 800 x 1,000 mm<br />

(W x D). In addition to the standard height<br />

of 42U, 48U is also available. A predefined<br />

cabling rack is also available. It consists of the<br />

complete base frame and is delivered with<br />

the rear wall, two side panels and a glass door<br />

for the front – assembled as desired or as<br />

a flat pack. All covers can be locked using<br />

the included key. The rack is available in RAL<br />

7035 light grey or RAL 9005 jet black.<br />

The Freenet Expert Line (EL) for server<br />

rooms uses the base frame and supplements<br />

it with a multifunctional strut that connects<br />

the outer profile with the 19" profiles at half<br />

height. Thanks to this expansion, a payload<br />

weight of up to 1,200 kg is possible.<br />

The third line, Freenet Superior Line (SL), is<br />

suitable for small data center applications. To<br />

this end, the base frame of the Classic Line is<br />

supplemented by two additional multifunctional<br />

struts and a hot/cold separation.<br />

All add-on elements such as side panels or<br />

doors, for example a perforated door with<br />

75 % air outlet or glass door, can be used<br />

for the three lines. The same applies to<br />

accessories such as vertical cable managers<br />

and vertical cable troughs.<br />

Secure Cabling<br />

for Crédit Agricole<br />

Crédit Agricole Centre-est chose an unusual solution for the<br />

renovation of its regional headquarters. The bank refrained<br />

from a relocation or demolition of the building and subsequent<br />

reconstruction, and instead carried out a comprehensive<br />

renovation of the building in Champagne-au-Mont-d’Or,<br />

which it moved into in 1987, demonstrating its commitment<br />

to sustainability and the preservation of architecturally<br />

valuable buildings. Between September 2020 and June<br />

2023, the 67,000 m 2 site was modernized in line with its<br />

historical character.<br />

Crédit Agricole approached R&M via INEO<br />

RAA to set up the new local area network.<br />

The bank wanted a high-end solution in line<br />

with the extensive structural and technological<br />

renovation of its headquarters. Due<br />

to its sensitive business operations, it had<br />

special requirements that R&M was able to<br />

meet quickly.<br />

A high-end solution for a permanently<br />

smooth operation of the local area network<br />

(LAN) was required for the technical redevelopment.<br />

The company does not tolerate any<br />

LAN or WLAN outages. The infrastructure<br />

with a commercial office network and wireless<br />

coverage was to guarantee incomparable<br />

service.<br />

With regard to the investment opportunities,<br />

a cabling solution from R&M in the category<br />

Cat. 6 A<br />

/Class EA was chosen. A backbone<br />

with fiber optic OS2 and OM4 cabling as<br />

well as three distribution nodes strengthen<br />

the infrastructure.<br />

Options for the future<br />

The first design study also targeted a solution<br />

compatible with an intelligent automated<br />

infrastructure management system (AIM). It<br />

had to be ensured that the network would<br />

support both current and future applications.<br />

The cabling system from R&M offers the<br />

advantage that an automated infrastructure<br />

management system can be added later at<br />

any time. Racks and patch panels are prepared<br />

for the installation of the inteliPhy monitor<br />

components. The AIM software inteliPhy net<br />

can monitor the entire network.<br />

Tried-and-tested cooperation<br />

With this project, R&M and its French partners<br />

once again demonstrated their smooth collaboration.<br />

Sales partner Exertis Azenn evaluated<br />

and delivered the network components and<br />

pre-terminated the copper links.<br />

R&M-certified installation partner Sterlan<br />

and installation company INEO Rhône-Alpes<br />

Ethernet has long since left the office building and is being<br />

used successfully in applications that place higher demands on<br />

the products in a transmission channel due to the operating<br />

environment. Despite harsher influences, the stability should<br />

be as reliable as in an office environment.<br />

The R&M portfolio contains various<br />

products, which are resistant to<br />

splashing water and dust, and are<br />

UV-protected.<br />

041.0<strong>65</strong>1<br />

Copper cabling guarantees the best data<br />

transmission, even outdoors and in harsh<br />

environments. The demand is particularly<br />

high in growing sectors such as the food and<br />

packaging industries, as well as in robotics<br />

and medical technology.<br />

even the harshest industrial environments.<br />

They are oil-repellent and resistant to high<br />

temperatures, fire and chemicals. They are<br />

resistant to splashing water and dust, and are<br />

UV-protected. This makes them perfect for<br />

machines and plants in all industries.<br />

friendly and error-free way, ensuring long-term<br />

operation in any manufacturing area.<br />

In addition to all of this, R&M experts also<br />

offer advice and services – and develop new<br />

product variants if demand arises.<br />

Developers and manufacturers who offer<br />

relevant products have the task of making<br />

them suitable for this purpose. This means<br />

the products have to withstand ambient<br />

conditions such as extreme temperatures,<br />

salt mist, dirt, humidity and/or vibrations. It<br />

is important that the connecting technology<br />

not only withstands these influences, but<br />

can also be installed in these environments<br />

without any errors.<br />

Manufacturing advantages<br />

Based on decades of expertise on the<br />

right material and practical experience,<br />

R&M products are designed to withstand<br />

R&M developers take higher requirements or<br />

additional services such as PoE into account<br />

from the very beginning of the product<br />

design concept. In addition, the products are<br />

continuously improved and manufactured in<br />

our own factories. And that’s not all: In order<br />

to guarantee the high quality standards at<br />

all times, we also develop all the necessary<br />

technologies ourselves.<br />

Simple installation<br />

Network reliability is not only determined by<br />

the quality of the components, but also by<br />

Corporate<br />

Provider of<br />

Custom-Made Solutions<br />

R&M is known for its custom-made offers and its willingness to develop new<br />

solutions together with its customers. Some of these solutions even end up being<br />

included in the standard range. One example of this is the range of Point of Presence<br />

(PoP) stations, which are being used at an increasing number of premises.<br />

Municipalities, public organizations and telecom<br />

operators often expect spontaneous and<br />

adaptable solutions for their FTTH projects.<br />

Almost all premises have different conditions<br />

for the expansion of the broadband<br />

infrastructure. This is where R&M helps with<br />

in-depth advice and turnkey, specific Point of<br />

Presence cabinets.<br />

The concept of the Point of Presence cabinets<br />

from R&M is popular in many countries. The<br />

initiative was launched in Germany, where<br />

the solution is now well established. Recently,<br />

R&M has started offering to pre-equip entire<br />

PoP stations in line with customer requirements<br />

in Belgium, too.<br />

Achieving goals fast<br />

A multi-stage process quickly leads to the<br />

goal. As a first step, R&M experts discuss<br />

the infrastructure requirements and the construction<br />

site situation with the customer. It<br />

is important to plan appointments in advance<br />

and to co-ordinate them closely with logistics.<br />

In most cases, custom-made solutions are<br />

required. R&M implements these internally.<br />

To this end, the various departments, market<br />

organizations, international manufacturing<br />

facilities and the company’s own supply<br />

chain work closely together. Consultants<br />

work at the R&M headquarters. Product<br />

managers plan the individual configurations<br />

and, if necessary, construct a prototype.<br />

Specially trained specialists install the passive<br />

technology for network transition, the main<br />

distributor, etc. in the cabin at a central plant.<br />

The portfolio covers almost the entire range<br />

of components used in such an installation.<br />

Ultimately, R&M delivers the containers to<br />

the construction site just-in-time.<br />

Close cooperation<br />

Local R&M contacts and technical consultants<br />

are in permanent contact with the project<br />

promoters and exchange detailed information<br />

with the supply chain. Experience shows that<br />

the best possible solution can only be found<br />

and implemented through close cooperation<br />

and constant exchange during the design<br />

stage.<br />

In the past three years, R&M has delivered<br />

more than 100 turnkey PoP cabinets, mainly<br />

in Germany. The FTTH project promoters<br />

primarily expected a distribution solution<br />

designed specifically for them, a reasonable<br />

price, good quality and professional support<br />

throughout the entire project stage, including<br />

on-site support.<br />

Equipment<br />

R&M can integrate all required passive<br />

and active technology in the turnkey PoP<br />

stations: Tubes for cable inlets and outlets,<br />

underground distribution chambers,<br />

raceway cable guides, 19" racks, ODF from<br />

the R&Mfoxs or PRIME program, electric<br />

installation, illumination, UPS, air conditioning,<br />

fire protection, burglar alarms, access<br />

control.<br />

The PoP stations are available in three standard<br />

sizes from 3 x 3 to 6 x 3 meters. The<br />

interiors provide space for the installation<br />

of 4,608 to 32,256 fibers or ports. The size<br />

depends on the customer’s ODF concept.<br />

030.7192<br />

050.7399<br />

Another important aspect is training the<br />

installers involved. This ensures that the PoP<br />

stations work perfectly from the outset. And<br />

customers can put their FTTH network into<br />

operation with ease.<br />

More Production Capacities<br />

for Fiber Optic Cables<br />

Focused on growth: R&M is further expanding its fiber optic cable production plant<br />

in Děčín, Czech Republic. The investments open up new opportunities for developers<br />

to implement innovative cable designs – and already present the first ones.<br />

R&M is continuously modernizing its existing<br />

systems with the aim of expanding production<br />

capacity for fiber optic cables. Two new<br />

extrusion lines have been installed at the<br />

plant in recent months. One of the new lines<br />

is a sheathing system for stranded cable<br />

050.7401<br />

050.7402<br />

R&M is expanding its machinery at the cable plant<br />

in the Czech Republic to continuously increase<br />

the production capacity for fiber optic cables.<br />

assemblies. It makes it possible to develop<br />

further designs in addition to the existing<br />

cable constructions. For example, cables with<br />

colored longitudinal stripes, aerial drop and<br />

feeder cables in single or double jackets for<br />

span lengths of up to 200 m as well as micro<br />

cables with optimized surface structures for<br />

improved blowability.<br />

Another extrusion line produces the semi-finished<br />

«loose tubes», which can be designed in<br />

a more versatile way. In particular, the diameter<br />

modularity is expanded and the wires can<br />

be produced with or without gel filling.<br />

Fiber optic range growing<br />

The R&M cable developers tackled the new<br />

possibilities early on and are now presenting<br />

some interesting new cable constructions.<br />

This includes the InHome Drop Cord, which<br />

was designed for Fiber in the Home or Fiber<br />

to the Office applications. Its simplex design<br />

is similar to that of a patch cord and meets<br />

the DCA classification as listed by the CPR.<br />

Suitable for direct connector mounting, it can<br />

also be mounted in the field and fits perfectly<br />

with FO Field connectors. In addition, the<br />

cable construction features a unique, densely<br />

buffered fiber construction that allows for<br />

peelability of up to 150 mm.<br />

Manufacturers can look forward to the wider<br />

range of Simplex patch cords. The range<br />

includes diameters of 1.7, 2.0, 2.4, 2.7 and<br />

3.0 mm. The MiniCore breakout cables for<br />

terminating MPO connectors are another<br />

highlight. Up to six individual cables (Mini-<br />

Core) are combined under a common jacket.<br />

Each MiniCore can be equipped with up to<br />

12 fibers, with aramid yarn providing strain<br />

relief. The cables are suitable for the direct<br />

termination of multi-fiber connectors (MPO)<br />

as well as for use with corresponding mini<br />

dividers for the production of data cables in<br />

distribution networks or for horizontal and<br />

collapsed backbone cabling.<br />

More Space<br />

for Splice Trays<br />

From family homes to building complexes –<br />

the Polaris box family from R&M ensures flexible<br />

optical termination both indoors and out. Now the<br />

terminal boxes are getting a new interior. This means<br />

even more space for additional splice trays.<br />

Buildings, data centers and industrial environments<br />

require ever-increasing capacity<br />

in fiber optic networks. This also requires<br />

a higher density of optical fibers and splice<br />

connections in the termination enclosures. To<br />

increase the capacity of the splice trays, R&M<br />

has designed new fiber inserts for the entire<br />

Polaris box family. With the space gained,<br />

even more subscribers can now be separated<br />

and splice capacity increased.<br />

Five family additions<br />

The Polaris boxes SCM 24 and 36 are the<br />

spearhead of the family. They hold up to 24<br />

or 36 FMTS 30 splice trays. The following<br />

cassettes are available: 1TPU splice trays<br />

with four or 12 HS or ANT and the 2TPU<br />

splitter tray for additional P2MP applications.<br />

When using the 12-fiber splice trays, up to a<br />

maximum of 288 pure splice connections can<br />

be terminated in the Polaris box 24 SCM, up<br />

to 432 with the P36. An adapter panel for 12<br />

or 18 SC, LC-D adapters can be retrofitted.<br />

The Polaris box SCM 12 is a medium-sized<br />

housing, in which the new fiber divider and<br />

three carrier trays are available for up to 12<br />

FMTS compact splice trays. They are suitable<br />

for 4 x HS or ANT splice protection holders<br />

per tray. This means that up to 12 participants<br />

can be separated or up to 48 splice connections<br />

can be realized. On demand, an adapter<br />

panel for up to 6 SC, LC-D connectors can<br />

be retrofitted.<br />

The small Polaris boxes SCM 4 and 6 even fit<br />

into tiny niches where space is tight. The fiber<br />

insert supports up to 12 crimp (ANT) or shrink<br />

(HS) splice connections. These boxes offer<br />

space for quick splitter integration as well as<br />

the first twelve splice connections without<br />

additional FMTS trays. In addition, up to<br />

four or six splice trays can be retrofitted. The<br />

adapter panel supplied supports up to four/<br />

six SC, LC Duplex connectors. This means<br />

that up to twelve LC patch connections can<br />

be terminated.<br />

With the P6 SCM, the FMTS-30 splice tray<br />

can also be used for pure splicing applications.<br />

This increases the splice capacity to up<br />

to 84 splice connections.<br />

021.6385<br />

Polaris box 24 SCM<br />

The plus for overlengths<br />

For additional overlength storage, a modular<br />

set is available for the SCM P12, P24 and<br />

P36. The fiber trays can be retrofitted either<br />

to the left or right next to the splice trays,<br />

free of tools. These allow optimum storage<br />

of loose tubes (multifiber) during loop<br />

installations or additional fiber storage of<br />

drop cables. The cable entry concept enables<br />

simple installation of cables and microtubes<br />

with diameters from 2.0 to 16.0 mm.<br />

In addition to the standard box range, R&M<br />

offers custom-made boxes for individual<br />

customer projects that are pre-equipped with<br />

splitters, plug connectors, pigtails, splice trays<br />

and the right cable sealing elements.<br />

For the Environment:<br />

Changes in Packaging<br />

R&M puts sustainability into practice on a daily basis. Customers can be confident<br />

that environment-friendly, resource-saving solutions are being developed. A current<br />

example: the packaging for the new FM45 Cat. 6 A<br />

EL.<br />

Plastic bags and films have been used as universal<br />

packaging material for decades. They<br />

are easy to handle, available everywhere,<br />

inexpensive and offer good protection.<br />

However, a considerable amount of waste<br />

is generated if they are not disposed of in<br />

the correct way. The films are also based on<br />

crude oil, which is far too valuable to be used<br />

to make disposable packaging. This is why<br />

R&M has resolved to gradually introduce<br />

an environment-friendly packaging strategy<br />

that goes easy on raw materials within the<br />

framework of the Group-wide sustainability<br />

strategy.<br />

The goals:<br />

– Elimination of disposable plastic packaging<br />

by 2027<br />

– Optimal use of cardboard boxes to reduce<br />

waste<br />

– Optimization of cardboard specifications to<br />

reduce resource requirements<br />

– Use of digital media to save on manuals and<br />

labels made of paper<br />

A cross-divisional working group is coordinating<br />

the activities. Their targets for 2024:<br />

– Consumption of 14 tons less new material<br />

for films thanks to the use of recycled<br />

material<br />

– Reduction of cardboard consumption by<br />

60 tons<br />

– Reduction of paper requirements for installation<br />

instructions by 11 tons<br />

– Process development for a new packaging<br />

concept<br />

Pilot project FM45 Cat.6 A<br />

EL<br />

The new field-mountable FM45 Cat. 6 A<br />

EL<br />

RJ45 connector is being used as a pilot<br />

for plastic-free packaging. First, R&M will<br />

evaluate how customers accept the packaging<br />

concept. In addition, experience with<br />

automated production and processing must<br />

be gained. As a result, R&M is expected to<br />

be able to save around 1,000 kg of plastic<br />

packaging and 90 kg of paper for installation<br />

instructions a year with this product.<br />

Various aspects need to be taken into account.<br />

A few examples:<br />

– The bag made of recycled paper must be<br />

printed directly. This means no sticker is<br />

needed for the label.<br />

– The darker paper reduces color contrast.<br />

This had to be taken into account in the<br />

layout.<br />

– The paper bag is opaque. For this reason,<br />

a product picture is printed on the bag so<br />

users can see what’s inside.<br />

– On the back, you can see a quick guide in<br />

the form of graphics. If you require more<br />

detailed instructions, you can find them<br />

online using the printed QR code.<br />

Presentation in wooden boxes<br />

To date, representative presentation boxes<br />

have often been used to launch new products,<br />

usually cardboard boxes with foam inserts.<br />

Overall, R&M does not actually use many of<br />

these presentation boxes. Nevertheless, with<br />

the market launch of the FM45 Cat. 6 A<br />

EL,<br />

the team also wanted to break new ground<br />

in terms of product marketing. The aim was<br />

to keep the presentation box completely free<br />

of foam and to consistently implement the<br />

«Reduce, Reuse, Recycle» concept.<br />

This was achieved with two concepts:<br />

A solution based on a sustainably usable<br />

wooden box was developed to be used when<br />

the focus is on representative properties.<br />

The box is not assembled from single parts,<br />

but milled from two boards of ash wood. A<br />

layered cardboard insert to accommodate<br />

single parts completes the solution.<br />

050.7404<br />

If the wooden box is no longer needed for<br />

product presentation, the cardboard insert<br />

can be recycled and the box reused for<br />

decorative purposes.<br />

When it comes to the convenient handing<br />

over of products for testing purposes, R&M<br />

does without a solid box. The products are<br />

packed between two layered cardboard<br />

inserts. A paper band holds the two halves<br />

together.<br />

All materials in this solution can be recycled<br />

after use.<br />
