T & S MTP / MPO fiber loop is a device used for parallel connection tests and an aging test of optical communication equipment. It can transmit the optical network signal from the transmitter to the receiver, forming the optical signal receiving and transmitting loop. MTP / MPO fiber loop provides a fast and efficient way to test the transmission capacity and receiving sensitivity of optical network equipment. T & S MTP / MPO fiber loop has 8F, 12F, 16F, 24F, 32F channels with low loss and conventional loss, single-mode and multi-mode options. It is used for optical network equipment self-test, network diagnosis and test, etc.

The loopback is both ends of fiber in a duplex connector or a multi-fiber connector, then the optical signal in the same connector, don't change signals or repeated back to its itself. It can provide an effective solution, test the emission ability of the network equipment and receive sensitivity, especially in 40/100G network communication through back signal positioning can be all kinds of potential phenomenon, so as to achieve optical fiber network in pairs on a single element or interface and effective test and evaluation of the Internet.
