Media Converters Introduction Using Media Converters Black Box Explains Media Converters. It seems simple enough: To convert between different media, you need a media converter. However, it's not as simple as that. There are three different types of media converters, and you need to find the right type for your scenario and application. Switched Media Converter The most common type of media converter is the switched media converter. These are economical, easy to build and simple to install. A switched media converter uses standard chipsets for switches, which enables the converter to run different speeds. Switched media converters autosense 10-, 100- or 1000- Mbps speeds. However, many things you encounter with a switch also apply to a switched media converter. Not all Ethernet frames (packets) pass through the switched media converter and you may experience some latency. If you need a media converter for your office network — for internet, e-mail, printing and file sharing — you can't go wrong with a switched media converter. Transparent Media Converter These media converters are fully transparent within their designated protocol. So any frame coming in on "Side A" gets converted and is output on "Side B" in the same manner. Because most media converters are generally converting optical to copper Ethernet, only a conversion from electrical to opto-electronic is done. Unfortunately, these media converters need to run on the same speed on both sides. This applies to the bandwidth (10, 100 or 1000 Mbps) and the half-/fullduplex setting. Protocol-transparent Media Converter The other main use of a media converter is to change between singlemode and multimode. In this case, a protocol-transparent media converter that works transparently and is independent from the can work Ethernet, Token Ring, ATM and Fibre Channel because they just adopt the wavelength. They're available for different speeds. Why is this so important to know Today, IP networks are used for more than just sending e-mail, accessing the Internet and print servers. Special devices exist for transferring audio, video, KVM, telephony and other services. Because not all these devices work with standard TCP/IP communication at standard frame length, you could experience unexpected results. For example, audio data transferred by UDP broadcast traffic have frames blocked by switches where "Broadcast Storm Protection" is enabled. And there are proprietary systems sending very big frames (Jumbo frames), which normal switched media converters block as well. Switched media converters also produce latency on your IP network, although one switched media converter will not do any harm. However, having more than one in your IP network can degrade your roundtrip time. Switched media converters are easy and economical, but make sure they're best for your applications. Advantages of Media Converters Cost Comparison Fibre Ethernet Switches can be very expensive. At the end of 2009, a 16 port branded fibre switch (low end) was costing upwards of £4K, whilst a branded Gigabit Fibre Switch module for a core switch, was typically costing just under £10K. Black Box Media Converters allow you to use existing fully functioned twisted pair switches and convert to fibre externally. This option can also provide flexibility and future proofing in one easy to install solution, at the same time as dramatically reducing the costs involved. A fully functioned 16 port twisted pair Gigabit Ethernet switch can cost as little as £150 depending upon model, and combined with a 16 port Gigabit media conversion chassis, a total solution of under £3.5K provides all the functionality required. But in addition, if the type of cable changes again, i.e. from a MultiMode cable to a Single-Mode cable, the chassis, power supply and any management system can be kept and only the actual cards will need to be replaced. A lot of the cards provide 10/100/1000Mbps connectivity on the twisted pair port and enable you to begin converting at either 10 or 100Mbps, yet provide all the future proofing you need to take you right up to 1 Gigabit to the desktop. This saves having to buy a 10/100Mbps fibre media converter now, and replace it in a year or two with a gigabit version. So if you are using a 10/100 or 100Mbps switch currently, but are thinking of moving to Gigabit later on, purchasing a Black Box 10/100/1000Mbps Media Converter system will provide all the connectivity you require today and tomorrow. Some of our latest Media Converters use SFP sockets for the fibre port. The advantages of SFP sockets is that they are another way of providing future proofing. SFP modules are very convenient and easy to use and also very easy to replace, without the expense of replacing the entire switch. And SFP’s can be replaced one port at a time, reducing the need to buy new switches just because a few ports are now using fibre. Moving up to 10Gigabit Ethernet networks, XFP’s provide the same functionality as SFP’s but provide the 10Gigabit speeds required for today’s high speed core networks. Available in copper (CX4) and both multimode and single-mode fibre versions, these XFPs provide the same future proofing as SFP’s in one compact, easy to install, practical solution. Purchasing an XFP based 10Gigabit Ethernet switch now, means you can provide the high speed network required today, whilst always being ready for the higher speed networks of tomorrow. Black Box XFP’s – because you don’t know what the future will bring. 6 Tech Support: 0118 965 6000 | Sales: 0118 965 6150

Frame Relay at 56K, T1, or E1 speeds Media conversion is often necessary because of the limited distance of copper cables. For 10 Gigabit networks, this is getting even more important because the segment length is limited on CX4 to just a few metres. If your severs are already equipped with CX4 connectors, or your 10 Gigabit switch has only CX4 connectors, this is the media converter for your 10 Gigabit network. It works transparently and gives you 100% performance. t E ch spE cs Humidity — 5 to 90%, noncondensing Operating Temperature — 0 to +50 o C Connectors — (1) 10 Gigabit CX4; (1) XFP Slot Power — External power supply Dimensions — 2.5(H) x 7.6(W) x 10.1(D) cm Item Code Price 10 Gigabit CX4 to XFP Media Converter LMC11001AE £3,243.42 info@blackbox.co.uk | www.blackbox.co.uk 7
