Multi-Source Agreement (MSA)

The MSA is a multi-vendors specification defining the transceiver form-factors (dimensions, electrical-connector, pinout, etc.) as well as the management interface, also called 2 wire interface.

The MSA enables the interoperability between transceivers vendors and switches/routers vendors. By being 100% MSA compliant, ProLabs transceivers are interoperable with all switches and routers vendors.
