ABSTRACT:
An optical receiver comprising: a photoelectric converting unit converting an input optical signal into an converted electrical signal; a splitting unit splitting the converted electrical signal into a plurality of split electrical signals; an amplifier amplifying one of the plurality of the split electrical signals with a first input time constant and thereby outputting an output signal; a detection circuit detecting an interruption of the input optical signal with a second input time constant on the basis of one of the plurality of the split electrical signals other than the one of the plurality of the split electrical signals input to the amplifier and thereby outputting a detection signal; and a delay circuit configured to delay the detection signal; wherein, the second input time constant of the detection circuit is smaller than the first input time constant of the amplifier.
