OIF Delivers Two Common Electrical I/O Agreements

The Optical Internetworking Forum (OIF) completed two Implementation Agreements (IAs) relating to Common Electrical I/O technology.


The first, CEI 11G-LR, addresses 11 to 13 Gbps applications over backplanes. This IA responds to the industry's move toward higher speed electrical signaling, driven by system vendors' desire to quadruple the bandwidth of existing systems without increasing the number of backplane traces.


The second IA, CEI Protocol (CEI-P) is a new protocol designed for use with the fast electrical interfaces developed by the CEI project team. A key feature of this new protocol is the Forward Error Correction (FEC) capability, which is tolerant of burst errors and substantially improves the error rate performance of a link. The FEC has the capability to improve the channel's bit error ratio by as much as 12 orders of magnitude.


The two new agreements build upon the existing CEI IA published last quarter that addressed 6 Gbps short and long reach and 11 Gbps short reach applications. http://www.oiforum.com
