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.

Prerequisites

The OTU board must be created.
