Terabit BiDi MSA posts specs for 800G and 1.6T interfaces

The Terabit BiDi Multi-Source Agreement (MSA) group releases version 1.0 of its optical specifications for 800 Gb/s and 1.6 Tb/s optical interfaces over 70 meters of OM4 multimode fiber (MMF). 

The MSA's specifications utilize the widely adopted dual wavelength bidirectional transmission technology. This provides an upgrade path to the large scale deployed parallel MMF cabling infrastructure. The specifications are built on the 100 Gb/s Ethernet MMF specifications.

The members of the Terabit BiDi MSA include Alibaba, Arista Networks, Broadcom, Cisco, Coherent, CommScope, Corning Incorporated, Dell Technologies, HGGenuine, Hisense Broadband, Lumentum, MACOM, Marvell, OFS, Panduit and Tencent.

"The transition to 100 Gb/s per lane signaling is rapidly underway, and the release of the Terabit BiDi specifications is just in time for the industry to adopt cost-effective and fast interfaces with VCSEL based solutions," said Tzu Hao Chow, MSA co-chair.

"Multimode bidirectional optical transceivers have been crucial for preserving the usefulness of already existing fiber cables in data centers as technology has progressed from 10 to 25 to 50 Gb/s per lane. The Terabit BiDi specification is a roadmap to continue this trend," said David Piehler, MSA co-chair.
