The Optical Internetworking Forum (OIF) has begun work on a 100G Serial Electrical Link project.
The very short reach (VSR) CEI-112G chip-to-module interface project will support a nominal lane rate of 112 Gb/s, enabling narrower interfaces to optical modules and is expected to be more energy efficient than previous interfaces. The CEI-112G-VSR specification doubles data rates over the current generation CEI-56G-VSR interfaces.
The OIF said this work will be followed by both shorter and longer reach projects.
“As bandwidth increases, electrical interfaces need to reflect that trend. Given the lead times, development of standards for the next generation of electrical links needs to start now,” said David Stauffer of Kandou Bus and the OIF’s Physical and Link Layer Working Group Chair and board member. “The OIF is continuing its roadmap for 100 Gb/s thru 400 Gb/s and beyond applications, addressing multiple reaches for chip-to-chip and chip-to module interfaces.”
