An optical signal transmitted by another terminal device that was used for compensation could be received by a device that is not the intended destination of said optical signal, resulting in the problem that confidentiality cannot be guaranteed for the information in said optical signal. This optical reception device is characterized by the provision of the following: a receiving means via which wavelength-multiplexed signal light is inputted; and a transmitting means that, in accordance with an identifier in an optical signal of a prescribed wavelength in the inputted wavelength-multiplexed signal light, forwards said optical signal.
