Use this procedure to configure the laser bias current high threshold on an optics controller to monitor and maintain optimal performance.
Use this task to laser bias current high threshold.
Procedure
-
Run the controller opticsR/S/I/P lbc-high-thresholdlbc-value command to configure the laser bias current threshold.
Example:
This is a sample which configures the high laser bias threshold on the controller optics.
