ABSTRACT:
Low-noise, bidirectional communications in a fiber optic cable is achieved by coupling a first end of the cable to an optical power source having an inherently broad spectral width. A second end of the cable is coupled to an optical detector having a detector bandwidth, such that the bandwidth of the optical power source is greater than the detector bandwidth. When the bandwidth of the optical power source is large compared to the bandwidth of the detector, the beat frequencies resulting from coherent Rayleigh noise fall outside the bandwidth of the detector and are not detected.
