Usage Guidelines

The laser of an optical module works in automatic restart mode or manual restart mode.

In automatic restart mode, the laser sends pulses at the interval set using the als restart pulse-interval command to detect whether the link is recovered. The pulse width is set through the als restart pulse-width command.
In manual restart mode, you must manually start the laser using the als restart command so that the laser can send a pulse. The ALS pulse width is set using the als restart pulse-width command.

If the fiber link recovery is detected in time, you can use the manual restart mode so that the laser can send pulses immediately. Therefore, data communication can be recovered rapidly.
