Establishing The Configuration Task; Enabling Als On An Interface - Huawei Quidway S9300 Configuration Manual

11 ALS Configuration
The laser can work in automatic restart mode or manual restart mode. By default, the laser works
in automatic restart mode.
11.3.4 (Optional) Starting the Laser Manually
When the laser works in automatic restart mode, you need to manually open the laser so that the
laser sends one pulse.
11.3.5 (Optional) Setting the ALS Pulse Interval and Width of the Laser
You can set the proper laser pulse interval and width to ensure energy conservation and emission
deduction and timely detection of fiber link recovery.
11.3.6 Checking the Configuration
After ALS is configured, you can the ALS configuration on a specified interface or in a specified
slot, including the ALS status, laser status, ALS restart mode, and ALS pulse interval and width.

11.3.1 Establishing the Configuration Task

Before configuring ALS, familiarize yourself with the applicable environment, complete the
pre-configuration tasks, and obtain the required data. This helps you complete the configuration
task quickly and accurately.
Applicable Environment
The S9300 controls the laser of an optical module by detecting the LOS on the optical interface;
thus, the S9300 provides security protection and saves energy.
According to the actual networking requirements, after ALS is enabled, you can:
