Helpful Fiber Loopback Cable



Fiber loopback cable and fiber loopback module are called fiber loopbacks, they can provide a simple and effective means of testing the capabilities of optical networking equipment. Fiber optic loopback cable is designed to provide a media of return patch for a fiber optic signal, offers a generous yet manageable fiber loop virtually eliminating bend loss, commonly used for fiber optic testing applications or network restorations.


For Example, Check Fiber Optic Transceiver By Loopback Test.


You can check your fiber optic transceiver through a loopback test, which is the easiest way to ensure your fiber optic transceiver, is working faultlessly. Loopback test means hardware or software method, a loopback test, feeds a received signal or data back to the sender. It is utilized as an aid in debugging physical connection problems.


Fan-out Patch Cords

Fan-out Patch Cords


On fiber optic transceiver manufacturing floors and in R&D labs, we usually use a fiber optic loopback module to verify the transceiver whether it is working perfectly as designed. Basically what the loopback module does is directly routing the laser signal from the transmitter port back to the receiver port. Then we can compare the transmitted pattern with the received pattern to make sure they are identical and have no error.
