WDM performance report in NCE (V100R020C10CP3605) ?

Dear friend!

Perform the following steps:

1. Open the Network Management app and choose Monitor > Performance > WDM Performance from the main menu. Click the Current Performance Data tab.

2. In the NE Explorer, select a board and choose Performance > Current Performance from the navigation tree.

3. In the Physical Topology, click an NG WDM NE. Expand the information panel, click NE Panel in the Operations area. (If the function menu is not displayed in the Operations area, add it to the Operations area by clicking  in the upper right corner.) On the NE Panel, select a subrack, right-click a board on the subrack and choose WDM Performance Browse from the shortcut menu.

Dear friend!

Please refer to the following information(The prerequisite is that the board supports the OD function and the license file has been activated):

Displaying the Trail Performance Analysis Window

1. Choose Configuration > WDM Optical Management > Optical Doctor on the NCE Network.

2. Management app. The Optical Doctor window is displayed.

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.

Method 3: You can also perform the following steps to display the Trail Performance Analysis window:

a. Choose Services > WDM Trail > Manage WDM TrailServices > View >WDM Trail > Manage WDM Trail from the Main Menu on the NCE Network Management app.

b. In the Set Trail Browse Filter Criteria dialog box, set filter criteria. The required trails are displayed in the trail list.

c. Right-click the desired OCh trail and choose WDM Optical Management > 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.

If the selected trail is not a trail in the Maintenance state, the Analysis button is unavailable.

4. Optional: Importing the Historical Performance Data of Trails. The historical performance data of the trail is displayed in the window.

You can select or deselect the Historical Data of the right-click menu in the window to display or hidden the historical data.

On the top of the window, the current and historical single-wavelength or multiplexed-wavelength optical power and single wavelength OSNR of selected trails are displayed in terms of column graph. At the bottom of the window, the signal flow diagram is displayed. In the histogram, select the power or OSNR bar of a node. Then the node is highlighted in the signal flow diagram. Similarly, after a user clicks a node in the signal flow diagram, the node is highlighted in the histogram.

In the histogram, select the power or OSNR bar of a node. Then you can view detailed parameter information for the node below the histogram.

In the signal flow diagram, click a node marked abnormal. All the exception information of the node is displayed.

The current attenuation value, historical attenuation value, and the design EOL value of the long fiber are displayed on the signal flow diagram.

Move your cursor onto the optical amplifier. The current and historical values of the attenuator and the OA gain are displayed on the window.

The icon on the OA node in the signal flow diagram indicates that the node is used to monitor optical power flatness.

In the signal flow diagram, right-click a board and choose WDM Configuration to locate the WDM interface of the board on the NCE. In this way, users can query the related parameters of the board.

Select and right-click the required board in the signal flow diagram, and choose Edit Maintenance Memo from the shortcut menu that is displayed. In the dialog box that is displayed, you can edit the board maintenance information. After you close the dialog box, the maintenance memo information is automatically saved. Only one memo can be configured for each board and each memo contains a maximum of 254 bytes. If the icon is displayed on a board in the signal flow diagram, a memo is configured for the board.

Analyzing the Performance Data of E2E Trails

In the WDM Trail Performance Analysis window, the Optical Doctor (OD) system visually displays the multiplexed-wavelength optical power, single-wavelength optical power, single-wavelength optical signal-to-noise ratio (OSNR), bit error rate (BER), and OSNR Loss of the monitored end-to-end (E2E) trails.

Prerequisites

OD routes must be configured and optical signal-to-noise ratio (OSNR) detection must be enabled; otherwise, single-wavelength OSNR data cannot be queried.

Historical single-wavelength optical power can be viewed only after OD routes are configured and OSNR detection must be enabled.

For the OSN 9800 NE, the NE data must be uploaded.

Background Information

On a trail for which the OD route is not configured, the WDM Trail Performance Analysis window will display the single-wavelength optical power and OSNR of OA boards according to the values scanned by the MCA or LS OA board. If no MCA or LS OA board is configured for the OA boards, no single-wavelength optical power or OSNR will be displayed for the OA boards.

The historical performance data of the trail is displayed in the window only after Importing the Historical Performance Data of Trails for the selected trail.

Trail performance analysis can be performed only 10 minutes after an OD route is configured in the Network Parameter Settings window.

The OD obtains device data at an interval of 10 minutes. Therefore, the performance data is not real-time data.

Single-Wavelength Optical Power Analysis

Click the Single-Wavelength Power tab. On the displayed tab page, query the single-wavelength optical power of all nodes on the trail.

The following describes the histograms on the Single-Wavelength Power tab:

The current and historical single-wavelength input and output power of the OTU boards and OA boards on the trail are displayed in histograms. The sequence for optical power bars of all boards must be the same as that for the boards in the signal flow diagram.

The horizontal dashed lines indicate the single-wavelength nominal input and output optical power of OA boards.

The input optical power threshold of the receive-end OTU board is represented as. When the current single-wavelength input optical power of a receive-end OTU board is beyond the permitted threshold range, a fatal error is displayed on the bar for the board. In addition, the OTU board is marked abnormal in the signal flow diagram.

If no optical power is obtained for a board, the corresponding bar for the board is not displayed and the board is marked abnormal in the signal flow diagram.
