Fiber Loopback Module is designed to provide a media of return patch for a fiber optic signal. Typically it is used for fiber 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.
Fiber Loopback Module is abosolutely an economical solution for a number of fiber optic test applications.
FS.COM supplies various kinds of single-mode and multimode Fiber Optic Loopback Modules, which are with different connectors including ST, SC, FC, LC, MU, MTRJ etc. Each module is functionally tested before shipping and is covered by a lifetime warranty.
