Single mode / Multimode Fiber Optic Loopback Module with SC / LC Connector

Singlemode/Multimode Fiber Optic Loopback with SC/LC Connector

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.
GKoptic supplies various kinds of single-mode and multimode Fiber Optic Loopback Modules. Each module is functionally tested before shipping and is covered by a lifetime warranty.
