Abstract
An optical communication system in which the degradation of the signal-to-noise-ratio during transmission is alleviated. An optical signal from an optical transmitter is propagated over a transmission line comprising optical fibers and optical amplifiers, and received by an optical receiver. The signal-to-noise ratio is improved by inserting an injection-locked laser device at a specified point on the optical transmission line, improving the transmission characteristics of the optical communication system.
