Simplify the Implementation of High Density 100G CXP


Data center bandwidth demands continue to grow, requiring higher capacity and throughput. The 100G/120G Ethernet is no longer new in data center optic market, but it’s still a complex act to efficiently and effectively upgrade existing 10G/40G architectures to these higher data rates, especially in a space-constrained application. In order to explore the approaches of smooth migration to high density 100G/120G network, this post will take multimode 100G CXP module as example, and illustrate some simplified scenarios when upgrading to these higher data rates.

Overview on 100G CXP Module

High density 100G CXP is very popular in the implementations up to 100Gbps for saving-space. This deployment can then leverage the 10G-per-lane channels to distribute the 10G data anywhere in the data center. 100G CXP module is designed to connect with an MTP/MPO-24 connector, which can be divided to 10x10G or 12x10G transceiver pairs. For 120G CXP, it is also possible to separate the signals into three QSFP+ transceivers, and then to three groups of 4x10G transceivers by using an 8 fibers MTP/MPO to LC breakout module or cable.

Direct Connectivity for two CXPs

For two 100GBASE-SR10 modules, direct link can be easily made via 100G MPO cable. For connecting two 120G CXPs, a cost-effective 24 fibers MPO trunk can also work well. Here uses an 24 fibers MPO (female) to MPO (female) OM4 polarity B trunk cable.

Connectivity Methods for CXP and SFP+/QSFP+

In this part, the scenarios applied for 100G to 10G connection, and 120G to 40G or 10G connection will be explained.

100G to 10G

Figure 2 shows a direct link for one 100G CFP module and ten 10G SFP+ modules. By using the 24 fibers MPO to LC duplex harness cable, the whole 100G from the CFP transceiver is connected to ten SFP+ transceivers (two LC duplex legs are not used in this link). The fanout legs are available to be the same length or staggered type, so as to meet different applications.

In figure 3, the interconnect for CFP and SFP+ transceivers is more flexible than the direct link. Here the 160 fibers MTP/MPO (male) breakout patch panel allows connectivity to any duplex path reachable by the patch panel. This method offers ultimate flexibility in allowing connectivity to any row, rack or shelf. Moreover, this breakout module can support up to eight groups of this 100G to 10x10G transmission. In such a high density link, it is suggested to use HD patch cables or LC uniboot patch cables to enable quicker and better cable management.

120G to 10G and 40G

When directly connecting one 120G CXP to twelve 10G SFP+ transceivers, a 24 fibers MTP-24 to 12 LC harness cables can do the job well. Here we use a customized high density bend insensitive female MTP-24 to 12 LC duplex OM4 breakout cable.

An option for breaking out a 120G CXP to three 40G QSFP+s is to use the 1×3 MTP/MPO conversion harness cable. Figure 5 illustrates implementation of a 1×24 strand MTP to 3×8 strand MTP conversion harness cable. Like the 12x10G segregation mentioned above, once split, the 3×8-fiber QSFP+ channels can be distributed through patch panels and 12-fiber based trunking to any area of the data center.

This article has illustrated some simplified implementation examples of 100G CXP modules. 24 fibers MTP/MPO trunk cable are suited for connecting two CXP modules. Breakout cables can achieve quick connection for CXP and QSFP+ or SFP+ optics, but when flexible patching is needed in the link, it would be better to adopt breakout patch panel. If you need 100G optics, FS.COM can offer you fully tested compatible 100GBASE-SR10, 100GBASE-SR4, 100GBASE-LR4 and 100GBASE-ER4 transceivers, etc.

Three Ways Fiber Optic Transceivers Promote Data Center

The data center is one of the most critical and dynamic operations in any business. As companies produce, collect, analyze and store more data, IT infrastructures need to grow as well to keep up with the demand. With all the data processing and transmission, it is only critical that every design aspect and component of your data center is properly optimized, including its fiber optic transceiver technology. The transceiver and other optical components need to meet the bandwidth requirement for storage, switch, and server applications. Now let’s see how will the optical transceivers promote data centers in the future.Fiber Optic TransceiversSmall Package Makes Sense
Optical transceivers are becoming smaller, but more powerful, which makes them an important piece in server technology. In fact, even though a transceiver is physically small, it can handle a network expansion or an entire install. This shrinking of transceivers allows for the improvement of servers. This reduces the overall footprint of servers and networks, which makes data centers smaller and streamlined. Optical transceivers also require lower power consumption, which means you get lower costs both in terms of design and electricity expenses.

Data Center Makes up Big Transceiver Market
Optical components are always being improved, which can only mean good things for data center managers. According to recent numbers, 2016 and beyond will be huge for the data center market and optical components as more companies require efficiency in their networks. Data centers make up 65% of the overall 10G/40G/100G optical transceiver market. Shipment of 10G transceivers continue to grow, but still has plenty of room to grow, especially as industry experts expect the Datacom optical transceiver market to reach $optical transceivers2.1bn by 2019.

40G and 100G Transceivers Pave the Way
Consumers and technology experts can expect optical transceivers to improve as data centers grow and the cloud industry expands. Manufacturers have introduced transceivers that can transmit data at 40Gbps and 100Gbps, while some startups are investing millions in developing technology that can achieve higher speeds. These and other improvements can only mean good things for businesses and consumers.

Significantly improving your company’s IT infrastructure is becoming an essential task, especially in this data-driven world. Optical transceivers and components are some of the little things that definitely can make a big difference in this effort. Fiberstore provide a variety of fiber optic transceivers with high quality and low price, from 1000Base SFP to 10G SFP+, 40G QSFP+ and 100G CFP. For more information, please visit www.fs.com.
