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).
