Setting the ALS Pulse Interval and Width of the Laser

Setting the ALS Pulse Interval and Width of the Laser

Context

The ALS pulse interval indicates the time between two consecutive pulse transmissions and applies to the automatic restart mode. The ALS pulse width indicates the pulse period and applies to the automatic restart mode and manual restart mode.

  • In automatic restart mode, a small pulse width and a long pulse interval save more energy but cannot ensure that optical link recovery can be quickly detected.

  • In manual restart mode, a small ALS pulse width saves energy but cannot ensure that optical link recovery can be quickly detected. In contrast, a large ALS pulse width ensures that optical link recovery can be quickly detected but wastes energy.

You can set a proper laser pulse interval and width to ensure energy conservation and timely detection of optical link recovery.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run als restart pulse interval pulse-interval

    The ALS pulse interval of the laser is set.

    By default, the ALS pulse interval is 100s.

  4. Run als restart pulse width pulse-width

    The ALS pulse width of the laser is set.

    By default, the ALS pulse width is 2s.

  5. Run commit

    The configuration is committed.
