400G BiDi MSA Group releases first multimode fiber optical transceiver specification
The 400G Bidirectional (BiDi) Multi-Source Agreement (MSA) Group says it has published its first 400G-BD4.2 Specification. The specification describes support of 400-Gbps over 100 m of multimode fiber via a dual-wavelength BiDi transmission approach. The specification leverages 100-Gbps BiDi for Ethernet applications and is compatible with existing parallel multimode fiber cabling infrastructure, the MSA asserts.
