When performing a 10-minute error-free test on a certain wavelength division channel, the local end uses an SDH analyzer to interconnect with the client-side interface of the OTU board, the OTU client interface at the opposite end needs to perform fiber self-looping, and solid attenuation must be added during self-looping.
