Question 125
When 10-minute error-free test is performed on a certain wavelength division channel, the local end uses the SDH analyzer to interconnect with the client-side interface of the OTU board. The peer OTU client-side interface needs to perform fiber self-loop. When you are self-looping, you must add solid decay.
