ROADM commissionig procedure is shown in the attachment.The most important fact in ROADM is direction and colorless transmission. Also OPA plays an important role for auto adjustment of attenuation in Local dimension and all receiving amplifier.

very useful for me as currently we are deploying ROADM

Dear all, can you see the attachment DWDM commissioning procedure? if not, please tell me. I will approve it. Thanks a lot.

Can you help in rectifying OA_LOW_GAIN alarms at different long haul links (beyond 100KM connected with RAU's)?
