OSNR of a board is abnormal

Dear friend!

OSNR is the ratio of signal to noise. A board does not have the OSNR feature. You can use a special meter to test the OSNR of the signals output by the board.

On NCE, if you have activated the OD function, you can perform an OSNR test on a wavelength.

1. Choose Configuration > WDM Optical Management > Optical Doctor on the NCE Network Management app. The Optical Doctor window is displayed.

2. Enter the WDM Trail Performance Analysis window.

Method 1: Select a site or fiber in OD VIEW. All activated OCh trails related to the site or fiber are displayed in the Trail Info window.

Method 2: On the Alarm Info tab, right-click one or more alarm records and choose View Associated Trail from the shortcut menu. In the trail list, all associated OCh trails are displayed.

In the trail list, right-click one or more OCh trails and choose WDM Trail Performance Analysis from the shortcut menu. The WDM Trail Performance Analysis window is displayed.

3. Select the desired OCh trail and click Analysis. The current performance data of the trail is displayed.

4. Click the Single-Wavelength OSNR tab. On the displayed tab page, query the single-wavelength OSNR of all nodes on the trail.

For more information, please click Analyzing Current Trail Performance.
