10Gtek Fiber Loopback 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.
