BRIEF INTRODUCTION
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.
