MPO Loopback

MPO loopback

MPO loopback modules are passive fiber optic devices used to loop transmit and receive channels back inside the same connector housing. They provide a practical way to test optical transceivers, network ports and cabling links without connecting to remote equipment.

The assemblies are available for 8, 12, 16 and 24 fiber MPO interfaces and can be produced in single mode or multimode versions. Typical uses include checking transmit power, receiver sensitivity, port mapping and signal continuity in 40G QSFP+, 100G CXP or CFP and related parallel optical systems. The compact enclosed design protects the internal fibers during repeated testing.
