Abstract

An optical transmission apparatus includes: an optical amplifier configured to amplify a wavelength multiplexing light to be transmitted, the wavelength multiplexing light being input thereto; a combining unit configured to combine a plurality of non-signal lights in such a way that angles formed between polarization planes of the plurality of non-signal lights of a wavelength of wavelengths belonging to an amplification band of the optical amplifier become equal, the wavelength being different from a wavelength of a polarization multiplexing signal light; and a wavelength multiplexer configured to generate the wavelength multiplexing light to be input to the optical amplifier by multiplexing the plurality of non-signal lights combined by the combining unit and the polarization multiplexing signal light.
