Introduction:
This Document describes the issue of unused waves are being monitored in optical side power
monitoring in CTC(Cisco Transport Controller) when we use 80-WXC card in ONS15454 device.

Note: It is just a cosmetic issue and not traffic impacted.The TNC is wrongly reporting ASE
(Amplified Spontaneous Emission or Amplified noise) power reading as channels power.

Side Power Monitoring feature
DWDM nodes allow you to view the side power levels on the Maintenance > DWDM > Side Power
Monitoring > Optical Side n tab, where n is A, B, C, D. Each existing channel will have an IN and
OUT power on each node side in the case of bidirectional circuits. OUT indicates the power on the
output port with respect to the side to which it is referred to. It is the last port of the side before the
first amplified port in the direction going from the node to the span or the output port of the side
itself if there are no amplified ports. IN indicates the power on the input port with respect to the
side to which is referred to. It is the first port of the side after the last amplified port in the direction
going from the span to the node or the input port of the side itself if there are no amplified ports.
