문제1
The difference threshold between the working and protection channels in 5 dB. The initial optical power on both channels is 2 dBm. When the fiber attenuation of the working channel increases, its optical power changes to -4 dBm and the optical power of the protection channel remains unchanged. This triggers optical line protection switching.

Signal flow analysis is used to divide an entire network into several OMSs, identify the faulty section, determine whether the fault is occurring unidirectionally or bidirectionally, and then locate the fault along the signal flow direction based on fault information.
