CH1~CH8: optical interface of multiplexing/ demultiplexing channel on
OMD board, CH1=1471nm, interval=20nm
CH0: 1310nm monitor channel interface on OMD5-1, which is
connected to the OSC interface of the NCP board

Configuration description
1. In Fig. 4.1-3, PCWAS boards are adopted to provide -48V DC power input for
the system ddl.
2. In this configuration 2-channel bidirectional OTU boards are adopted. Other
types of OTU boards can also be used as required.
3. The monitoring channel is the 1310nm channel. Therefore, the CWU shelf is
configured with an OMD5-1 board to provide an interface for the 1310nm
channel. If the monitoring channel is 1510nm. The CH3 interface of the
OMD5-1 board should be connected with the OSC interface of the NCP board.
4. If the ZXMP M600 needs to implement the multiplexing function, for a certain
wavelength, a multiplexing board (SRM42 or GEM2) can be used without OTU.
In addition, an SMU shelf should be added for installing the multiplexing board.
