DUAL-MODE FIBER OPTIC TELECOMMUNICATIONS SYSTEM AND METHOD

摘要

An optical data transmitter includes at least one light source (12), a phase modulator (16) for phase modulating light from the light source, and a controller (18) having an input for receiving an electronic data stream, the controller in a first mode controlling the phase modulator so as to create phase-modulated optical signals in the light as a functions of the electronic data stream and the controller in a second alternate mode amplitude-modulating the light as a function of the electronic data stream. A dual-mode receiver, an optical data transmission system and a dual-mode optical signal are also disclosed.
