Conditions for the MCA board of the BWS 1600G to determine a wavelength loss and report the CHAN_LOS alarm
Question: What is the condition for the MCA board to report the CHAN_LOS alarm when wavelength monitoring configurations are correct? CHAN_LOS Answer: The MCA board determines a wavelength loss when it detects the following wavelength conditions: 1. The optical power is lower than -40 dBm. 2. The optical power is greater than 5 dBm. 3. A wavelength exceeds the standard wavelength by ±0.14 nm. 4. The signal-to-noise ratio is smaller than 7.5 dB. 5. If the difference between the maximum and minimum optical power is greater than 10 dB, the MCA board determines that the wavelength with the minimum optical power is lost.
