Multi-Source Agreement

January 15, 2024

Welcome to our MSA Documentation Hub! The MSA serves as a comprehensive specification from multiple vendors, defining form factors, dimensions, electrical connectors, pinout, and the management interface. It is not only at the base for a seamless functioning between transceivers and switches/routers, but also ensures the correct interoperability between transceivers of different manufacturers and vendors. Need to check on some specs or want to understand how the coding of a transceiver influences its function? We’ve done the hard work for you and compiled all relevant documents here below:
