Setting the Board Working Mode
Before using a board, you need to set the board and port working modes based on the site conditions.
Configuring the Service Type The services can be transmitted normally only when the type of the services at the interface of the board is the same as the actual service type.
Configuring the Service Mode
If services such as OTU1 are input to a board, you need to configure the service mode of the board.
Modifying Port
The client-side port and line-side ports of the OTU board in the NG WDM can be a color port or a grey port. Set the port type based on the small form-factor pluggable (SFP) optical module used in the equipment. Set the port type based on the small form-factor pluggable (SFP) optical module used in the equipment.
Setting Automatic Laser Shutdown
Automatic laser shutdown is a function of automatically shutting down the laser when there is no input light and the laser stops emitting optical signals. For example, when an optical interface board does not bear services, a fault occurs on the fiber, or the received optical signals are lost, the laser is automatically turned off. This reduces the on period of the laser, extends the service life of the laser, and prevents hazardous laser radiation exposure from causing permanent eye damage.
