Optical Fiber Communication Link

Abstract

A communication includes an analog input configured to receive an analog signal. An analog to digital converter is configured to provide a digital signal output based upon the analog input. A modulator is configured to modulate a laser based upon the digital signal thereby generating a modulated optical signal. An optical fiber carries the modulated optical signal and an optical detector arranged to receive the modulated optical signal from the optical fiber and provide a received output. A digital to analog converter digitizes the received output and provides an analog output based respective of the analog signal provided to the analog input.
