Loopback Patch Cord Description


Fiber Loopback Patch Cord can provide a simple and effective means of testing, It is used to diagnose the problems of optical networking equipment. Sending a loopback test to network equipment, one at a time, is a technique for isolating a problem. The fiber loopback modules can be with various jacket types and cable diameters, and they can be with different terminations and length. Fiber optic loopbacks are with compact design, and they are compliant with fast Ethernet, fiber channel, ATM and Gigabit Ethernet. SOPTO also offer custom assemblies. The common fiber optic loopback cable types are: SC, FC, LC and MT-RJ.
