    Abstract: PURPOSE: A light transmission system is provided to enable high quality transmission on each of a plurality of multiplexed signal channels. CONSTITUTION: A signal light formed by multiplexing a plurality of signal channels in which the interval of an optical frequency is greater than and equal to 400GHz or is less than and equal to 12.5THz is transmitted from a light transmitter(110) to a Raman amplifier(130) via an optical transmission path(120). On the Raman amplifier(130), excitation light from excitation light source parts(135,136) is supplied to an optical fiber(137) through optical couplers(133,134). The multiplexed signal light inputted to the Raman amplifier(130) reaches the optical fiber(137) through an optical isolator(131) and the optical coupler(133) and Raman amplification is performed on the optical fiber(137). The Raman-amplified multiplexed signal light is outputted from the Raman amplifier(130) through the optical coupler(134) and the optical isolator(132).
