ABSTRACT:
An optical amplifier for wavelength multiplexing optical transmission has an optical amplifier for amplifying wavelength-multiplexed signal light in which signal lights having wavelengths different from each other are wavelength-multiplexed and outputting the amplified wavelength-multiplexed signal light from an output terminal, and a light-removing portion which is disposed along the light path after the optical amplifier and removes spontaneous emission light existing between the wavelengths of the signal lights included in the amplified wavelength-multiplexed signal light.
