Description
LC Fiber Loopback, Single Mode and Multimode
Fiber loopback is a simple and powerful passive fiber optic device designed to test network cables, Ethernet ports and network switches, providing a return patch medium for fiber optic signal loopback test to diagnose the network problems. By sending a loopback test to network equipment is definitely an economical solution to isolate network problems. In data center applications, fiber loopback testing is the most convenient way for transceiver maintenance.
LC Loopback functions as an external loopback tester that can be directly plugged into the Ethernet ports to simulate a network signal that loops back to the source device to test the transmission capability and receiver sensitivity of network device. LC fiber loopback module features a small form factor with a compact housing cover for easy push and pull. 9um micro cable is always used inside the loopback module. LC loopback cable is much more like a simplex patch cable, but incorporate two LC connectors by a duplex clip. Usually LC loopback cable uses 2.0mm jacket cable. Same as standard patch cord, available with short LC boots, PVC, Plenum, LSZH cable jacket options, available with singlmode 9/125µm, multimode 50/125µm and 62.5/125µm.
