US Patent 7505695 Optical receiver and optical transmission system
All edits
The present invention includes 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, a lowpass filter which imposes the band-limitation on the electric signal output from the opto-electric converter, an amplifier which amplifies the output signal of the lowpass filter, and an electric equalizer which performs an equalization processing on a waveform of the electric signal output from the opto-electric converter are provided, and a full width at half maximum of the optical band-limiting filter is set to be equivalent to or smaller than a bit rate frequency of the optical signal.
