You can adjust the gain of Huawei optical amplifier unit to change the optical power. Adjust the gain according to the project design optical power.
Prerequisites
You must be an NM user with “NE maintainer” authority or higher.
The board must be created.
Impact on System
None
NMS
Background Information
The OAU1 is the optical amplifier board with tunable gain.
In actual use, calculate the gain range that can be set according to the intermediate insertion loss.
The nominal gain refers to the gain of only signal light, that is, the difference between the nominal output and input optical power of signals of the board.
The actual gain is the difference between the measured output and input optical power of the board. Hence, the actual gain includes both the gain of signal light and the gain of noise light. In normal cases, the actual gain is slightly greater than the nominal gain according to the number of added wavelengths.

Adjust the gain of the optical amplifier boards.
When the nominal gain as set exceeds the permitted gain range of the board, the nominal gain cannot be changed.
