PROBLEM TO BE SOLVED: To provide an optical reception module, an optical receiver, and an electronic circuit by which a function of detecting the interruption of a received optical signal can be mounted into the optical reception module while reducing its size.SOLUTION: The optical reception module 2 includes a photodiode 20 for converting a received optical signal to an electric signal, an LOS detection circuit 23 for detecting the interruption of the optical signal based on the electric signal, and a pair of differential output terminals 26-4 (that is, a differential output terminal 26-4-1 and a differential output terminal 26-4-2) for synthesizing a first signal corresponding to the electric signal and a second signal corresponding to the result of the detection of the signal interruption by the LOS detection circuit 23 and outputting the synthesized signals. |
