Effective Solutions for 10G/40G Connectivity

As the growing demand for faster access to larger volumes of data, coupled with emerging high-speed network standards and rapidly advancing technology, fiber optic cables and cabling components have become a very popular element in data centers and high-speed networks. And when 10G fiber is the norm in most data centers today, the 40G fiber is also becoming commonplace. In this article, three effective solutions for 10G/40G connectivity will be introduced.

Breakout Cabling Solutions

A breakout cable is a multi-strand cable which is divided into different specification cables. For example, a 40Gb breakout cable has four 10Gb duplex cables totaling eight strands, while a 100Gb breakout cable has 10 duplex cables and 20 strands.

How Does Breakout Cable Work?

To understand how breakout cabling solutions work, take integrating 10Gb servers into a 40Gb network for example. For each port on the switch, an MTP/MPO breakout cable which has an MPO/MTP connector on one end and four duplex LC connectors on the other end is needed. The MPO/MTP connector is plugged into the transceiver that connects with 40Gb switch and each duplex LC connector plugs into a 10Gb port on each server. If the switch has up to 32 40G ports, up to 128 10G devices can be connected to it using breakout cables.

Advantages

This breakout cabling solution enables slower equipment to be connected to higher-speed equipment successfully, such as the 10Gb servers and 40Gb switch in our example. Up to 128 10Gb devices can be connected to a 32-port 40Gb switch.

MTP Modular Cassettes Solutions

MTP cassette modules provide secure transition between MTP and LC or SC discrete connectors. They are used to interconnect MTP backbones with LC or SC patching. Supporting various network cabling standards, the cassettes are easy to mix, match, add and replace as the connectivity needs grow or change.

How Does MTP Modular Cassette Work?

Modular fiber cassettes are the key to modular systems. Available in multiple variations, the cassettes allow users to interconnect different fiber speeds simply by plugging standard LC cables into one side of the cassette and one or more standard MPO/MTP cables into the other side.

For 10G connectivity, MTP/MPO cassettes are used to connect 10G device to 10G device, especially when the distance between two devices is too long. And for 40G connectivity, MPO/MTP cassette is used to connect 10G device to 40G device. Modular patch panel solutions offer users an easy-to-use solution that works with the equipment of today and can easily be transitioned for the networks of tomorrow.

Advantages

Modular cassette solution also has many advantages. First, this solution offers flexibility and scalability for network upgrade. Second, with fiber modular cassettes, this solution allows users to manage cables in any direction—horizontal or vertical, front or back. Finally, by managing varying port densities and speeds in a single high-density patch panel, users can save valuable rack space and data center costs.

Fiber Breakout Panels Solutions

Fiber breakout panels are ready for plug-and-play deployment out of the box. They provide increased access between ports, thus enabling the ease of moves, adds, and changes of cables. It’s the increased access that help fiber breakout panels offer a cost saving, simple and efficient cable management solution for future high-speed network connection.

How Does Breakout Panels Work?

Fiber breakout panels offer a simple, cost-effective alternative to breakout cables. To understanding how it works, let’s take one of 40G QSFP+ breakout patch panel for example. The 96 fibers MTP-LC 1U Ultra Density 40G QSFP+ breakout patch panel has 48 duplex LC ports front and 12 MTP Elite rear ports. When it’s installed, the 40GE QSFP ports with MTP fiber cable will be connected to the back of the panel, and then LC fiber cables will be linked to the LC port. This 40GB QSFP breakout panel logically groups the ports in 4 duplex LC ports, and is available for single-mode or multimode applications.

Advantages

Breakout panels solution can connect different equipment such as 10G, 40G and 100G, offering more flexibilities for network cabling. Besides, as the breakout panels are pre-terminated, they can be easily installed and help save installation time.

Conclusion

With increasingly higher network speeds always just around the corner, network build and upgrade also get much attention. Choosing suitable connectivity solution for 10G/40G connectivity which allows you to meet your current connectivity needs while simultaneously investing in your future also should be attached more importance. The contents above give an explanation of three cabling solutions. Hope it may help you.

40G Fanout Solution for Data Center

With the requirement of high-speed Ethernet in data center, the migration from 10G to 40G is beginning. Fanout technology has been widely applied in 40G data center to get higher data rate and higher port density. The principle of fanout technology is just like the water pipeline in a building. Water is transferred from the trunk pipeline, and then trunk pipeline fans out into several pipelines that have smaller diameters to bring the water to every house.

A device needing to be connected to two or several devices with different physical interface is very common. So the superiority of fanout technology is brought into full play, especially in the distribution layer of 40G data center and adapting lower data rate to 40G in cabling. Several widely used fanout/breakout assemblies in 40G data center will be introduced in this article.

40G MPO Fanout Cables

A MPO fanout cable is a multi-fiber optical cable containing several individual tight buffered optical fibers with one end terminated with a male or female MPO connector and the other end usually terminated with several LC connectors.

MPO fanout cable

Figure 1

Various MPO fanout cables are available in the market now. The fanout/breakout cable which is able to fan out into 12 or 24 fibers is most commonly used in 40G cabling deployment.

Figure 1 shows a typical 12-fiber MPO breakout cable (also called MPO harness cable) with OM3 optical fiber as the transmission media. This 12-fiber MPO fanout cable is terminated with a male MPO connector on one end and 6 duplex LC connectors on the other end. It can work from MPO trunk backbone assemblies to LC fiber rack system in high density backbone cabling from 40G device to 10G devices.

There is also a little bit smaller MPO fanout cable, of which the fibers fan out directly from the MPO connectors. This mini MPO harness cable can be easily put into patch panel and increase the cabling density effectively (see Figure 2).

MPO cassette

Figure 2

MPO cassette is another special type of MPO fanout cable. It is designed for those who want to have everything in neat and tidy. The MPO cassette breaks the traditional design of the fanout cable. It can offer better cable protection and management by housing one or several mini size MPO fanout cables in a cassette. For a 12-fiber MPO cassette, there will be a 12-fiber mini direct fanout MPO cable inside the cassette. With one MPO in the back side of the cassette and six duplex LC connectors in the front (see Figure 3).

This type of cassette can be installed in the standard rack in data center. To achieve higher cable density, more 12-fiber or 24-fiber mini MPO fanout cables are installed for 40G transmission. For instance, Figure 3 is a 24-fiber MPO cassette containing two 12-fiber fanout cables, thus there are two 12-fiber MPO connectors on the cassette. A 24-fiber MPO cassette can also have a mini size 24-fiber fanout cable inside the cassette. This cassette will only have one 24-fiber MPO connector in the back side. No matter what the fiber count and connector type are, these MPO cassettes can be customized in Fiberstore according to your requirements.

40G Fanout Direct Attach Cable

By offering direct interconnection for devices in data center, direct attach cable also has fanout design. Converting one form factor to a different form factor is necessary in many cases. For instance, a 40G device may be connected to one or several 10G devices for distribution or adapting. With fanout direct attach cable, this process would be much easier. This pre-terminated components can also increase the reliability of data center effectively.

A 40G direct attach cable usually has a 40G QSFP+ connector on one end, no matter it uses copper or fiber as the transmission media. And four 10G XFP connectors or four 10G SFP+ connectors are terminated on the other end of the 40G direct attach cable.

QSFP-8LC AOC

Figure 4

Sometimes it also needs to convert QSFP+ to LC interface. There is also another type of 40G DAC can satisfy this requirement. This kind of DAC is attached with a QSFP+ on one end and several LC connectors on the other end (see Figure 4). Figure 4 shows an active optical cable (AOC) with one end plugged into a QSFP+ switch and the other end attached with four duplex LC connectors which are separately linked to four 10G SFP+ transceivers. These 10G transceivers are then plugged into 10G switch with SFP+ ports. In this way, 40G cabling to 10G cabling is achieved.

Conclusion

Fanout technology is playing an important role in 40G data center. Products like 40G break out cable, cassette and 40G break out direct attached cable can all be found and customized in Fiberstore. Different connectors, cable length, fiber count etc. can all be specially designed according to your application.
