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 21):
The optical receiver according to  claim 16 , further comprising: an analog-digital converter configured to convert the amplified electrical signal to a digital signal; and a digital signal processor configured to process the digital signal.
