A fiber-optic communication system for an aircraft including: a light source operable to generate light; a transceiver in optical communication with the light source, the transceiver including a control input and a reflector; an optical fiber in optical communication with the transceiver; and a light detector in optical communication with the optical fiber. The transceiver is operable to generate an amplitude modulated light signal by selectively reflecting the light received from the light source into the optical fiber using the reflector according to information received at the control input. The light detector is operable to receive the amplitude modulated light signal from the optical fiber and to detect an amplitude of the amplitude modulated light signal to extract the information.
