Housing and Pull-tab of LC/SC Loopback
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.
