Next Generation 100G CFP Modules - CFP2 & CFP4
As 100-Gbps transmission is reaching the field, work is already underway on the second generation of the technology. Upcoming advances will lower costs, increase efficiency, and make 100G applicable to a wider variety of carrier and data center applications. But similar to what has happened in the 10G market, we expect that a different set of optical components will dominate the second and third generation of coherent 100G deployments, where power dissipation, density, and cost are key. Among these optical components, the small form factor pluggable transceiver which supports 100G is one of the essential part, because fiber connectivity in higher-speed active equipment is being condensed and simplified with plug-and-play, hot-swap transceiver miniaturization. And when it comes to providing 100G coherent functionality in a pluggable form factor, CFP and its next generation modules (e.g. 100GBASE-LR4 CFP2) will come to be discussed.
100GBASE-LR4 CFP2 Transceiver
The CFP Multi-Source Agreement (MSA) is currently defining two next generation 100G form factors - CFP2 and CFP4. Compared to the existing CFP form factor, CFP2 and CFP4 will respectively double and quadruple front panel port density. The new form factors take advantage of advances in optics and IC integration, and increase in electrical I/O rate from 10G to 25G. They will support existing and future duplex single-mode fiber (SMF) and parallel multi-mode fiber (MMF) interfaces. The following picture shows the evolution of 100G transceiver modules during 2010 - 2015. Through increasing in front panel density, the next generation of CFP modules will be with a smaller module size and lower power. This is enabled by increased integration of optics and ICs, and by increase in electrical I/O rate from 10G to 25G reducing the I/O width from 10 lanes to 4. In fact, this motivation of immediately taking advantage of advances in integration and I/O technology is similar with the 10G modules.
Evolution of 100G CFP during 2010-2015
CFP2 and CFP4 modules are defined to support existing and future SMF applications. The primary application is 100GE-LR4 10km duplex SMF, with CAUI-4 electrical I/O to be defined in. CFP2 will support 100GE-ER4 40km and 100G DWDM optics when integration technology matures. CFP2 and CFP4 can also support the future 100G structured data center 1000m duplex SMF application. In addition, CFP and CFP2 modules support 100GE-SR10 parallel MMF with CAUI interface. CFP2 and CFP4 modules can also support 100GE-SR10 with CAUI-4 electrical I/O by using a 4:10 Gearbox IC. In fact, an extension of the 100GE-SR10 application is break out of the parallel MMF cable into ten duplex MMF fiber pairs to enable high 10GE-SR front panel density. 10x10G electrical I/O can directly support this functionality. However, CAUI-4 electrical I/O does not support this because it breaks up 10GE lanes into 5G Virtual Lanes. To preserve 10GE lanes, the Optical Internetworking Forum (OIF) is defining a Multi Link Gearbox (MLG) standard which will support 10:4 multiplexing and 4:10 de-multiplexing of ten 10GE asynchronous streams across a 4x25G electrical I/O interface. We can see the differences between CFP, CFP2 and CFP4 in the following picture.
Comparison of CFP, CFP2 and CPF4
Fiberstore Launched the 100G CFP and CFP2 LR4
CFP is widely available in the market, especially with the development of 100G Ethernet in recent years. Fiberstore, the leading manufacturer and supplier of optical communication products, strives to offering the best solution for their customers.
