Summary:PROBLEM TO BE SOLVED: To achieve an increase of transmission distance of wavelength multi-light.SOLUTION: A light amplifier 2 that amplifies input wavelength multi-light comprises: an excitation light part 26 that outputs excitation light; a light amplifying part 25 that amplifies the wavelength multi-light according to the power level of the excitation light. The wavelength multi-light has the number of wavelengths smaller than the maximum number of wavelengths input to the light amplifier 2. The power level of the excitation light is determined on the basis of the maximum number of wavelengths.SELECTED DRAWING: Figure 2 【課題】波長多重光の伝送距離拡大を安価に実現する。【解決手段】入力される波長多重光を増幅する光増幅装置２において、励起光を出力する励起光部２６と、前記励起光のパワーレベルに応じて、前記波長多重光を増幅する光増幅部２５と、を有し、前記波長多重光は、前記光増幅装置２に入力される最大波長数以下の波長数であり、前記励起光のパワーレベルは、前記最大波長数に基づいて決定される。【選択図】図２
