Then we can compare the transmitted pattern with the received pattern to make sure they are identical and have no errors. 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.
