Through the return signal (mainly connecting the TX transmitting end to the receiving end of the RX in pairs), various potential abnormalities in the network link can be detected to achieve the test and evaluation of a single component or interface on the optical fiber network and the network. It is an ideal choice for testing the transmitted optical power and receiving sensitivity.
