Overview

Overview

Purpose

As network scale enlarges, device power consumption increases enterprise operating expense. Energy saving becomes the major concern in network construction. Devices use multiple energy-saving technologies to reduce power consumption.

Energy-Saving Management Features Supported by the Device

The device supports energy-saving features such as automatic laser shutdown (ALS).

  • ALS

    The automatic laser shutdown (ALS) mechanism controls the pulse of the laser of an optical module by detecting the Loss of Signal (LOS) on an optical interface. The ALS mechanism protects operators against laser injury and saves energy.

    When ALS is disabled, if the optical fiber link fails, data communication is interrupted. However, the optical interface and the laser of an optical module are enabled. If the laser of an optical module still sends pulses after data communication is interrupted, energy is wasted and eyes of operators may be hurt.

    When ALS is enabled, if the optical fiber link fails, the software automatically disables the laser of an optical module from sending pulses on the optical interface after detecting the LOS on the optical interface. When the faulty optical fiber link is recovered, the software detects that the LOS of the optical interface is cleared and enables the laser to send pulses.
