#FIBER LOOPBACK PLUG PATCH#
The two most commonly used loopback cable 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. And we offer custom assemblies for fiber optic loopbacks such as custom connector configurations and special polishing. Each of the loopback is functionally tested before shipping. We make fiber optic loopbacks strictly according to industry standard. Similar as fiber optic patch cords, fiber loopback can be with various jacket types and cable diameters, and they can be with different terminations and length.
Optical loopback adapters provide system test engineers a simple but effective way of testing the transmission capability and the receiver sensitivity of network equipment.įOCC loopbacks are precision terminated and feature extremely low loss characteristics for transparent operation in the test environment and in form of cable and module types. They are designed for testing, engineering and the burn-in stage of boards or other equipment. Further, by having to measure signal strength and loss at the physical downstream location, it is often necessary to remove the dust cap in order to provide access to the ferrule, thus exposing the ferrule to contaminants and potential physical damage. This time consuming procedure results in increased deployment costs in FTTx networks.
In the past, in order to test the optical continuity of optical fibers originating at a central office that pass through a tap point and terminate at a multi-fiber ferrule, it was necessary for a field technician and/or optical signal detection equipment to be physically present at the end of the tether in order to measure signal strength or loss through the total length of optical fiber. Sending a loopback test to network equipment, one at a time, is a technique for isolating problems. For the testing applications, the loopback signal is used for diagnosing a problem. Typically used for fiber optic testing applications or network restorations. They can provide a simple and effective means of testing the capabilities of your optical networking equipment.
Fiber loopback cable and fiber loopback plugs are called fiber loopbacks.
