LC/UPC Duplex Singlemode Loopback Module

The Fibre Loopback Module is designed to provide a media of return patch for a fibre optic signal. Typically it is used for fibre optic testing applications or network restorations. For the testing applications, the loopback signal is used for diagnosing a problem. Sending a loopback test to network equipment, one at a time, is a technique for isolating a problem. The Fibre Loopback Module can provide an economical solution for many fiber optic test applications.
