The input optical power and output optical power of the board ports are important indexes to measure the laser performance. Laser performance is crucial for the quality and transmission distance of signals. To keep the entire transmission system running stably, you must guarantee the laser performance. That is, control the input and output optical power of the ports and the fluctuation of the upper and lower threshold of the input optical power within the appropriate range, and correct or alert the optical power offset.
Procedure
- Choose from the main menu (traditional style); alternatively, double-click Fix-Network NE Configuration in Application Center and choose from the main menu (application style).
- In the NE list, select a board and click
. - Click Query to query the optical power information from the NE.
A prompt appears telling you that the operation was successful. - Double-click a cell in the Input Power Reference Value (dBm) or the Output Power Reference Value (dBm) column to specify the corresponding power reference value.
NOTE: If the power values that you query are correct, perform the following operations to specify the reference values:
- Right-click a cell in the Input Power Reference Value (dBm) column and choose from the shortcut menu.
- Right-click a cell in the Output Power Reference Value (dBm) column and choose from the shortcut menu.
- Click Apply. The power offset is based on these values.
- Optional: Click Save Networkwide Reference Value and click OK in the Confirm dialog box to save current power value of the entire network as the reference value. The Operation Result dialog box indicating the operation is successful is displayed. Click Close.
