An MPO adapter (also called an MPO coupler) is a passive fiber optic component used to connect two MPO connectors together. This ensures a stable and accurate connection, allowing optical signals to pass between them with low loss. Designed to unleash high-speed data center capabilities, MPO Cable Assemblies and Adapters use high-density MTP and MPO-style connectors to deliver streamlined connectivity, high port density, superior loss performance and simplified maintenance for the high-bandwidth networks of tomorrow.
