This object reports an enumerated value indicating the Automatic Laser Shutdown (ALS) response behavior when Loss-Of-Signal is detected in the backward direction. On DWDM network interfaces, it enforces laser safety by controlling whether the laser shuts down automatically to prevent eye-safety hazards. A concrete example is setting this to 'enabled' (1) to ensure the transmitter laser automatically powers off if signal returns from the far end in an unexpected way.
