New 400G BiDi MSA Group Driving Development of Low Cost 400 Gb/s Multimode Optical Fiber Data Link Specifications Targeting Modern Data Centers

Consortium of industry leaders join forces to accelerate specification of 400 Gb/s Ethernet optical interfaces based on optical bidirectional technology for multimode fiber.

SAN JOSE, California – July 9, 2018 - The 400G Bidirectional (BiDi) Multi-Source Agreement (MSA) Group today announced its formation as an industry consortium promoting adoption of interoperable 400 Gb/s optical transceivers for 100 meter multimode fiber (MMF) link distances. The MSA is dedicated to defining optical data link specifications based on a dual wavelength bidirectional transmission technology which enables a reduction in the fiber count relative to other solutions. The target solution leverages both the widely adopted 40 Gb/s and 100 Gb/s BiDi Ethernet solutions and is compatible with the widely available and deployed parallel MMF cabling infrastructure.

Founding members of the 400G BiDi MSA include Alibaba, Broadcom, Cisco, Corning Incorporated, Foxconn Interconnect Technology, InnoLight Technology, Inphi Corporation and Sumitomo Electric.

The 400G BiDi MSA specification addresses short reach applications including the critical high-volume reaches in modern data centers between switches. The 400G BiDi MSA participants are responding to an industry need for lower cost and lower power consumption solutions in 400 Gb/s form factors that bidirectional multimode technology can provide.
