Open XR Optics Forum releases 400G MSA specs

The Open XR Optics Forum released its first Multi-Source Agreement (MSA) specifications for 400G transceivers.  

The specifications were developed by the Forum's transceiver working group, which includes representatives from 11 member companies. The goal of these specifications is to define standards that ensure interoperability among products from different vendors and support multi-sourcing of compliant coherent transceiver modules.

The release includes two key documents. The first sets out specifications related to the mechanical form factor and client interface, while the second document details the optical and electrical interface requirements. 

These specifications are part of the Forum's broader objective to foster the adoption of advanced coherent network architectures, both point-to-point and point-to-multipoint, by promoting interoperability across different vendors. This approach is intended to enhance network flexibility and achieve cost efficiencies.

The specifications released are titled "Open XR Transceiver Optical and Client Interface Specification" and "Open XR 400G Optical Module Form Factor Hardware Specifications." Additionally, two more documents, focusing on the management interface between pluggable modules and host devices, and signal format specifications, are in development. These will complete the suite of Open XR Optics-compliant transceiver specifications.

The specifications can be downloaded from the Open XR Optics Forum website:
