Does this only measure the optical level on the line port or can it give light levels for each colour on the CWDM?

The OPD is only measuring the power of the monitor port. And the main purpose of OPD is to monitor the link. When the link loss is too large or the link is broken, the OPD will alarm. OPD cannot measure the optical power of each CWDM channel port. by M***n on 06/05/2021
