Finisar, Opnext and SEI announce 40-100Gb/s optical transceiver MSA

Optical module, component and subsystem makers Finisar Corp of Sunnyvale, CA, USA, Opnext Inc of Eatontown, NJ, USA and Sumitomo Electric Industries Ltd (SEI) of Tokyo, Japan (together with subsidiary ExceLight Communications Inc of Durham, NC, USA) have announced the CFP multi-source agreement (MSA), which aims to define a hot-pluggable optical transceiver form factor to enable 40Gb/s and 100Gb/s applications, including next-generation High Speed Ethernet (40GbE and 100GbE). Pluggable CFP transceivers will support the ultra-high bandwidth requirements of datacom and telecom networks that form the backbone of the internet.

According to industry analysts, IP traffic is expected to nearly double every two years through 2012, potentially resulting in core network bandwidth shortages. The IP traffic volume will be driven by high-quality video services like VOD (video on demand) and IPTV as well as the availability of high-speed and high-capacity access networks such as FTTx and WiFi.

To prevent these shortages, carriers and service providers are already planning the deployment of next-generation high-speed network protocols. The Institute of Electrical and Electronics Engineers (IEEE) is currently working on the standardization of 40Gb/s and 100Gb/s Ethernet under its P802.3ba Task Force. In addition to the existing 40Gb/s telecom standards, both the OIF (Optical Internetworking Forum) and the ITU-T (the International Telecommunications Union’s Telecommunication Standardization Sector) are working on standardizing SDH/OTN telecom interfaces for long-haul transmission of 100 Gigabit Ethernet.

Pluggable transceiver modules compliant to the CFP MSA will be used on these 40Gb/s and 100Gb/s interfaces. The CFP MSA is defining the specifications required to support multiple applications using the same form factor. These applications include various protocols (such as 40GbE, 100GbE, OC-768/STM-256, OTU3), media types (multi-mode and single-mode fiber optics) and link distances. The CFP MSA uses numerous innovative features like advanced thermal management, electromagnetic interference (EMI) management and 10Gb/s signal integrity design to define the transceiver mechanical form factor, the optical connector, the 10x10Gb/s electrical connector with its pin assignments, the MDIO-based transceiver management interface and the hardware required on the system host board.
