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 can provide an economical solution for many fiber optic test applications. Loopback provides a media of return path for a signal, no matter the signal is for testing purposes or network restoration. In the case of testing, 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. Its performance is as good as that of a general. Available type including SC, MT-RJ, MU and LC. Bare fiber, 0.9mm cable, 2.0/3.0mm cable are all available. ThIs is an attenuated fiber loopback module used for testing and provisioning fiber optic data links. The features SC connectors and single mode fiber with an attenuation level of 15dB, which allows for directly connecting transmitter and receiver ports (looping back) without the need for a separate fiber cable and inline attenuators.
