Monitoring Wavelengths by Using the MCA Board

If the system requires the multi-channel spectrum analyzer (MCA) board, you need to enable the MCA board to monitor wavelengths. The station that is configured with the MCA boards usually uses the MCA boards to check the OSNR of a single wavelength and check whether certain wavelengths are dropped.

Prerequisites

The MCA boards must be configured.

Procedure

In the NE Explorer, select an MCA board and choose Configuration > WDM Interface from the Function Tree.
Click By Board/Port(Channel) and select Monitor Wavelength from the drop-down list.
Select the wavelength to be monitored on the board and set Wavelength Monitor Status to Monitor. Click Apply.
Select the board that is enabled for wavelength monitoring and choose Configuration > Laser Spectrum Analysis from the Function Tree.
Set Port Number and select the port to be analyzed.
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.
Optional: Enter a value in the Compensation Power (dBm) text box to modify the compensation power value. Click Refresh.
Click Query to start the spectrum analysis. The Spectrum Data, Spectrum Waveform, and Profile are displayed in the user interface.
NOTE:
- Click X-Axis Frequency to specify that the X-axis for the Spectrum Data, Spectrum Waveform, and Profile represents the frequency.
- Click X-Axis Wavelength to specify that the X-axis for the Spectrum Data, Spectrum Waveform, and Profile represents the wavelength.
