<2> ALS: Enable or disable ALS function. Automatic Laser Shutdown (ALS)
is a technique used to automatically shut down the output power of the
transmitter in case of fiber break according to ITU-T G.664. This is a safety
feature that prevents dangerous levels of laser light from leaking out of a
broken fiber, provided ALS is provisioned on both ends of the fiber pair. The
sequence of events is as follows. If a fiber is cut, the receiver will detect a
Loss Of Signal (LOS). The ALS agent will turn off the transmitter. The
receiver at the far end will then detect an LOS and its ALS agent will turn off
the transmitter. In this way the entire fiber will go dark.
