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.
