system with a channel spacing of 50 GHz. The MCA in the CRZ system with a channel spacing of 50 GHz
only supports the function to detect the power and the center wavelength..

Note1: The loss brought by online optical switch and the coupler is considered for the FMU. The dynamic
value is 1-2 dB smaller than the value of the OTDR component. Besides, the OTDR effective dynamic range
in online monitor mode is different from that in standby fibre monitor mode.
Note2: Test conditions: The pulse width of the test signal is 10 ns; the return loss is not more than -35 dB.
Note3: Test conditions: The pulse width of the test signal is 10 ns; the return loss is not more than -35 dB.
