Whether OPA commissioning is supported for wavelengths added on the MRx, MRxV, M40, or M40V boards in the WSD9+RMU9 configuration

9

When the RMU9 board is used to add wavelengths, OPA commissioning is supported when OTU boards are directly connected or connected to the MRx, M40V, or MRxV boards. When the MRx or M40 board is connected, however, single-wavelength commissioning is not supported. This is because an EVOA is integrated into each add port of the RMU9 board but the RMU9 board cannot commission single wavelengths as WSS modules do. When the MRx or M40 board is connected, no single-wavelength commissioning point is available in the wavelength adding direction. Only multiplexing-wavelength commissioning is supported. When OTU boards are directly connected or the M40V board is connected, single-wavelength commissioning is supported at each EVOA.

Difference between M40V and M40
Both M40 and M40V are optical multiplexer boards that multiplex a maximum of 40 single wavelengths into one multiplexed wavelength. Their main difference is that each optical port on the M40V board is equipped with a built-in electrical variable optical attenuator (EVOA) to adjust the input optical power of each channel.

Whether OPA is supported in the OAU>M40V>D40V>OAU pass-through direction
The OAU>M40V>D40V>OAU pass-through direction supports OPA

Whether the NQ2 board supports tunable wavelengths
