Abstract:
An optical reception apparatus ( 1 ) of the present invention includes: a local oscillator ( 11 ) outputting local oscillation light ( 22 ); an optical mixer ( 12 ) receiving a multiplexed optical signal ( 21 ) and the local oscillation light, and selectively outputting an optical signal ( 23 ) corresponding to the wavelength of the local oscillation light from the multiplexed optical signal; a photoelectric converter ( 13 ) converting the optical signal ( 23 ) output from the optical mixer into an electric signal ( 24 ); a variable gain amplifier ( 15 ) amplifying the electric signal ( 24 ) to generate an output signal ( 25 ) whose output amplitude is amplified to a certain level; a gain control signal generating circuit ( 16 ) generating a gain control signal ( 26 ) for controlling the gain of the variable gain amplifier ( 15 ); and a monitor signal generating unit ( 17 ) generating a monitor signal ( 27 ) corresponding to the power of the optical signal ( 23 ) using the gain control signal ( 26 ).

Claim (Index 16):
An optical receiver comprising:\n a local oscillator configured to output a local oscillation light; a variable optical attenuator configured to attenuate power of an input multiplexed optical signal comprising a plurality of optical signals; an optical hybrid configured to receive one of the plurality of optical signals by interfering with the local oscillation light; a photo detector configured to convert the received optical signal to an electrical signal; an amplifier configured to amplify the electrical signal with a gain; and a processor configured to output, to the amplifier, a gain control signal corresponding to the gain, wherein when an amplitude of the gain control signal decreases, the variable optical attenuator increases attenuation of the power of the input multiplexed optical signal.
