Optical transceiver interoperability refers to the ability of transceiver modules from different manufacturers to function correctly with a range of networking equipment—switches, routers, servers, and optical transport gear—without compatibility issues. Countless compatible fiber optic transceivers have been employed in network deployments. A wise selection is of great significance in today's crowded. In today's network deployment, compatible optical modules have been widely used, but users still have concerns about the quality, interoperability, and compatibility of optical modules when choosing them.
