Hi
You should first define the boards used in the DWDM NEs .
I will explain simpliest example when you have only OTU / MUX-DEMUX / Amplifiers :
If you have SDH signal for Example STM64
connected to OTU board like LSX you sould
1- connect the STM64 to the LSX client ports (TX, RX) in the power margin from 0 to -14.

2- Then in U2000 define for the LSX the lambda and the type of correction FEC/AFEC.
3- Next connect the OUT port of LSX to the port of MUX related to the lambda , -Next connect the in port of LSX to the port of deMUX related to the lambda .
4-using OSA adjust the power of the new lambda to be same as the adjacent in the MUX board as you can .
5- Then connect OSA to the amplifier MON port then adjust the channel power to the single power nominal power for that board (u can find it in document) for example for OBU3 it is -19 and that all for Transmit site in the receive site u just connect the fiber from DEMUX to the LSX IN port and be sure it is in the range 0 to - 14 adjust the power usually using fixed attenuators .
Then start the commissioning for the signal in the reverse direction the same as we did in the Tx steps 1 to 5 .

- The middle site is usually OLA doesnt need any commissioning in adding single channel.

I hope that is useful.

Hi there!

The transmission network that consists of DWDM devices only transmits the signals sent by SDH devices from point A to site B. Transparent transmission is performed in the middle. The fiber is equivalent to the fiber that directly connects site A and site B. Therefore, a straight line is displayed on the NMS.

If all WDM NEs that transmit signals are displayed between SDH NEs, In this case, the network topology becomes very complex, and it is extremely difficult for engineers to perform network maintenance.

Thanks!
