MPO Loopback
Our MPO loopbacks are built for daily use on production lines and in data centers. The internal fibers are fully enclosed and strain-relieved, so the module survives thousands of mating cycles while delivering repeatable loss.
Single-mode and multimode versions cover OS2, OM3 and OM4 interfaces, with insertion loss options matched to the equipment under test. During diagnostics the loopback exposes transmit power faults, receiver sensitivity problems, port mapping errors and polarity mistakes in 40G QSFP+, 100G QSFP28, CXP and CFP environments.
