Commissioning Input Optical Power of OTU Boards

For details, see the following operations:

1. Query the input optical power of the OTU on the NMS.

Log in to the NMS. Double-click the stations to be queried in the Main Topology. The Running Status of the stations to be queried is displayed.

Right-click an NE, and choose NE Explorer to display the NE Explorer window.

Select the desired OTU board, and choose Configuration > Optical Power Management from the Function Tree.

Click Query. A prompt is displayed indicating that the operation is successful. Click Close.

2. Compare the queried input optical power of the OTU to the range of the input optical power of the OTU.

If the actual input optical power is higher than the upper threshold of the input optical power of the OTU, increase the EVOA attenuation for this channel. The actual input optical power is then within the range of the input optical power.

If the actual input optical power is lower than the lower threshold of the input optical power of the OTU, decrease the EVOA attenuation of this channel. After the attenuation is adjusted to the minimum value, if the actual input optical power is still not within the range of the input optical power, check the internal fiber connections.

Hello,
Commissioning Requirements You need to select and configure a fixed attenuator at the IN optical port of the OTU board on the east and west receive ends respectively, based on the input optical power range of the OTU board. By doing this, the input optical power to the OTU board can meet the OTU design requirement.
