Loopback Fiber Patch Cord

Product ID: Loopback Fiber 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.

The two most commonly used loopback fiber patch cord are SC and LC fiber Connector type, just like fiber patch cord assemblies, loopback fiber patch cord are classified by single mode type and multimode type. Typically single mode SC and LC type loopback fiber patch cord are blue color, typical multimode SC and LC type loopback fiber patch cord are beige color, and this also goes with the practice of fiber patch cord. Loopback fiber patch cord can be 9/125 single mode or 50/125 multimode, or 62.5/125 multimode.
