Abstract
The optical signal amplification apparatus of this invention includes a plurality of optical fiber amplifiers connected in series, each optical fiber amplifier including: an optical fiber doped with rare earth ions; and a pumping light source for emitting pumping light for exciting the optical fiber, wherein the power of signal light input into each optical fiber amplifier is set so that the value of a distortion component of the signal light output from the optical fiber amplifier is equal to the value of a distortion component of the signal light input into the optical fiber amplifier and that the distortion component of the signal light output from the optical fiber amplifier increases when the power of the signal light input into the optical fiber amplifier increases. An optical fiber transmission system including the optical signal amplification device is also provided.
