The spectrum analyzer unit provides the built-in in-service spectrum analysis and monitoring functions. The unit monitors parameters for each optical channel, such as central wavelength or frequency and the optical power and OSNR, and reports the results to the SCC board and the Web LCT for data analysis.
Procedure
- In the NE Explorer, select an optical spectrum analyzer board and choose from the Function Tree.
- Click
. In the dialog box, enter the type of the peer NE connected to the local NE, set compensation power value, and then click OK.
NOTE: - Due to the insertion loss of the MON port, the optical power reported through the MON port may differ from the actual optical power. Calibrate the power by setting the Compensation Power (dBm).
- You can modify the value of Compensation Power (dBm) based on actual requirements.
- Click Query to query optical spectrum analysis data from the NE. The spectrum analysis result is displayed by list in the upper pane, and is displayed by graphics and profile in the lower panes.
NOTE:
After you select the spectrums of one or more wavelengths in the spectrum data area, the wavelengths are highlighted in the spectrum waveform area accordingly. After you select a wavelength in the spectrum waveform area, if the selected wavelength is the center wavelength of one of the received optical signals, the NM automatically selects the corresponding spectrum in the spectrum data area.
- Optional: Click Print to print the result of the spectrum analysis.
