FTTH LoopBack Fiber Optic Patchcord LC Singlemode Cable
Fiber Optic Loopback Description:
The fiber optic loopback typically it is used for fiber 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.
Similar to patch cables, fiber optic loopback can be with various jacket types and cable diameters. The covered Shell protects the fiber and creates a smaller footprint than the non-shelled one.
Fiber Optic Loopback is designed to provide a media of return patch for a fiber optic signal
