OIF Starts CEI 25 Project for Ultra High Bandwidth

December 13, 2005

The Optical Internetworking Forum (OIF) started two Physical and Link Layer Working Group (PLL WG) projects. The Common Electrical Interface (CEI) 25 project will address electrical interfaces of 20 to 25+ Gbps for both chip-to-chip and backplane applications.

The published CEI Implementation Agreement (IA) enables backplane interfaces to operate up to 11 Gbps. This is the first step in addressing the ultra-high bandwidth requirements presented by the OIF's Physical Layer User Group.

The working group will also develop an implementation agreement targeting 120 km reach lengths using alternate signaling transmitter technology. This effort extends the work the OIF completed earlier this year in the published “Interoperability for Long Reach and Extended Reach 10 Gbps Transponders and Transceivers” document.

The new implementation agreement will support ITU-T Study Group 15 work on future application codes.
