Abstract: PROBLEM TO BE SOLVED: To compensate for Raman effect by producing a gain inclined against Raman inclination in advance and applying the inclined gain to the spectrum of optical signals transmitted through an optical fiber. SOLUTION: A gain inclined against Raman inclination in advance is produced and the inclined gain is applied to the spectrum of optical signals transmitted through an optical fiber. For example, when an optical signal is transmitted from the output of an optical amplifier 100-i, e.g. 100-1, the gain is inclined at the low end of spectrum. Then a receiving optical amplifier, for example, an amplifier 100-2 amplifies a received signal and processes it again so that the power level of the optical signal is preliminarily inclined against Raman inclination produced in a transmitted light transmission line. With this constitution Raman effect can be offset.

Abstract: An optical amplifier is adapted to cancel the Raman gain of an optical transmission path that degrades those optical signals occupying the low end of the bandwidth such that the power is transferred from the latter signals to the optical signals occupying the high end of the bandwidth. More specifically, the optical amplifier adjusts the gain that it applies to the optical signals so that it favors the signal components at the low end of the bandwidth.
