Zusammenfassung:	An optical amplification apparatus that amplifies input wavelength-division multiplexed light includes a pump light source that outputs pump light, and an optical amplifier that amplifies the wavelength-division multiplexed light in response to a power level of the pump light. The number of wavelengths multiplexed in the wavelength-division multiplexed light is equal to or less than the maximum available number of wavelengths input to the optical amplification apparatus. The power level of the pump light is determined based on the maximum available number of wavelengths.
