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).

Abstract: PURPOSE: An optical amplification module, an optical amplification apparatus and an optical communications system are provided to realize a wide-band gain spectrum with a small relative gain non-uniformity in L band. CONSTITUTION: An optical amplification apparatus(100) comprises a light-receiving device(151) connected to the optical coupler(111), a light-receiving device(152) connected to the optical coupler(112), a pumping light source(153) connected to the optical coupler(113), a pumping light source(154) connected to the optical coupler(114), a temperature detecting device(161) and a temperature adjusting device(162) which are disposed in contact with or in the vicinity of the Bi type EDF(130), and a control unit(190) for regulating operations of the optical amplification apparatus(100) as a whole. The optical coupler(111) branches out a part of the multiplexed signal light fed therein by way of the input end(101), outputs thus branched part to the light-receiving device(151), and outputs the remaining part to the optical isolator(121). The light-receiving devices(151,152) receive the parts of multiplexed signal light having arrived there, and output electric signals having values corresponding to respective optical powers of thus received parts to the control unit(190).
