MPO/MTP loopback (Loopback) is a passive optical device, which contains MPO/MTP loopback jumpers, which pass both ends of the optical fiber into an MPO/MTP connector, so that the optical path is in the same connector without changing the signal or repeating the signal back to itself. It can provide an effective solution to test the transmitting ability and receiving sensitivity of network equipment, especially in 40/100G network communication, it can locate various potential phenomena through the return signal, so as to achieve a single component or interface on a paired optical fiber network And effective testing and evaluation of the network.
MPO/MTP loopers are available in multiple configurations to accommodate 8-, 12-, 16-, and 24-fiber MPO/MTP connectors and several fiber configurations to suit the port under test. Its streamlined and robust housing design provides greater stability and reliability.
