1. An optical receiver comprising:

  • an optical band-limiting filter which imposes a band-limitation on an input optical signal;

    an opto-electric converter which converts the optical signal output from the optical band-limiting filter into an electric signal; and

    an electric equalizer which performs an equalization processing on a signal waveform of the electric signal output from the opto-electric converter, wherein a full width at half maximum of the optical band-limiting filter is equivalent to or smaller than a bit rate frequency of the optical signal.
