100G Lambda MSA Consortium Members Release Updated Specifications and Collaborate to Validate Optical Interoperability at 100 GbE and 400 GbE

 The 100G Lambda Multisource Agreement (MSA) Group, which has quickly expanded to 39 member companies, has announced the release D2.0 of three specifications based on 100 Gb/s per wavelength PAM4 optical technology. These specifications target applications for data centers and service provider networks, enabling multi-vendor interoperability of optical transceivers produced in various form factors by different manufacturers.

These updated 100 GbE interface specifications are designated 100G-FR and 100G-LR for duplex single mode links over 2 km and 10 km respectively. The MSA reports that it has also updated the 400G-FR4 specification for 400 GbE duplex single mode fiber links that rely on multiplexing 4 wavelengths of 100 Gb/s PAM4 modulated optical signals. In addition, the MSA says it is also working on a 400G-LR4 specification for a 10 km reach at 400 GbE.

100G Lambda MSA Group Collaborated on Testing Interoperability 

In addition to releasing the specifications, members of the 100G Lambda MSA Group reported the success of their optical interoperability private plugfest of collaborative testing. Twelve of the member companies came together for two and a half days of testing to validate the compatibility, testability, and optical interoperability between members’ module or test equipment designs for the newly released specifications. MSA member firm, MultiLane, hosted the activities. The focuses of this event included testing optical interoperability for 100 GbE and 400 GbE modules and modules that support 4x 100 GbE breakout. This private plugfest ensures that member companies’ products meet the 100G Lambda MSA specification and interoperate before being released for production.

The 100G Lambda MSA Group will host module interoperation demonstrations in the 100G Lambda MSA booth (Booth #123) at the European Conference on Optical Communication (ECOC) Exhibition, September 24-26 in Rome, Italy.
