Loopback is a type of duplex or multi-fiber connector in which both ends of fibers are in the same connector. Signals input into a loopback have no change and get back to the loopback directly. It provides an effective solution to test the transmission ability and receive sensitivity of a network equipment. Especially, the returning signal can detect potential problems in 40G/100G communication network, so as to effectively test and evaluate optical fiber network on a single element or interface.
