Loopback patch cord

Loopback fiber patch cord (Loopback fiber cable) provides a media of return path for a signal, whether the signal is for testing purposes or due to network restoration. Loopback fiber patch cord can be regarded to be the two connectors on the same piece of simplex fiber optic patch cable put together, thus it forms a loop. 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 patch cord.

We provide various type of loopback fiber patch cord, includes ST, FC, SC, LC, MU, MTRJ, E2000. Our loopback fiber patch cords are with compact design and they are compatible with Fast Ethernet, Fiber Channel, ATM, and Gigabit Ethernet Short wavelength devices. Similar to fiber patch cords, loopback fiber patch cord can be with various jacket types and cable diameters, and they can be with different terminations and length. We also provide custom assemblies for loopback fiber patch cord to meet your requirement.
