Fiber optic loopback testing is the easiest way to ensure that the transceiver works faultlessly. Features: Used for Testing 50/125 Multimode Fiber 100. This series features FC, LC, and SC connector types. Each cable is individually tested and uses a generous yet manageable fiber loop to eliminate bend loss. Then we can compare the transmitted pattern with the received pattern to make sure they are identical and have no errors. The 50/125 multimode loopback cables from L-com provide an economical solution for numerous fiber optic test applications. Thus, during the testing process, the loopback module directly routes the laser signal from the transmitter port back to the receiver port. The former one is to send out laser signals and the latter is to receive signals. As we all know, fiber optic transceiver has two ports, a transmitter port and a receiver port. And the fiber loopback test can be utilized to check whether the fiber optic transceiver is working perfectly as designed.
It is used as an aid in debugging physical connection problems.
But here I’d like to introduce one of its common application-fiber optic loopback testing.Ī fiber loopback test is a hardware or software method which feeds a received signal or data back to the sender. Fiber optic loopbacks can be used in a number of applications such as equipment interconnection, device pig-tailing, premise networks, patch panel applications and communications connections.
