Software to implement the wavelength monitoring and management of OMCA boards

61

To implement high-precision OSNR measurement of boards such as OMCA, you need to configure the OD function on the NMS. The OD function is available only after an OD wavelength monitoring and management license is loaded.

Method used to set the wavelength to be monitored by the MCA board
In the NE Explorer, click the desired MCA board and choose Configuration > WDM Interface from the navigation tree. In the pane on the right, click By Board/Port(Channel), and select Monitor Wavelength from the drop-down list.

Whether the wavelength-tuning function of a board is achieved by the board software or optical module
The wavelength-tuning function of a board is mainly achieved by the optical module, but with the help from the board software.

Whether manual configuration is required for the WMU board to implement wavelength locking
The wavelength locking function is achieved after the centralized wavelength monitoring function is configured on the WMU board. When configuring the wavelength monitoring function, you need to understand the transmission direction and fiber connections of each OTU board, and check which optical port of the WMU board is connected. Currently, the following wavelength locking modes are supported: If the OTU, WMU, and optical-layer boards are configured on the same NE and you configure logical fiber connections, wavelength locking can be automatically performed without any operation. If the OTU and WMU boards are configured on the same NE but optical-layer boards are configured on another NE, you need to configure the mapping between the OTU board and the WMU board. If the OTU and WMU boards are configured on different NEs, ensure that the two NEs are in the same optical NE and you need to configure the mapping between the OTU board and the WMU board. Before the configuration, ensure that the DCN communication between NEs is normal.
