Abstract
An optical repeater system for optical communication that comprises a light source for providing a light of frequency ν0, and a beam splitter for synthesizing said light from said light source and optical communication signal pulses including Stokes light corresponding to said frequency ν0 introduced by Raman effect in the optical fibers, the optical repeater system being characterized in that the signal pulses are amplified with induced Raman effect in the optical fiber caused by the light and the dispersion characteristic of the optical fiber.
