PROBLEM TO BE SOLVED: To provide an optical transmission/reception module capable of rightly implementing optical transmission/reception of a control signal in simple device configuration.SOLUTION: An optical transmission/reception module 10 comprises: an LD driver 11 and a laser diode 12 for converting an inputted electric signal including a main signal and a control signal into an optical signal and transmitting the optical signal; and a TIA/LIA 13 and a photodiode 14 for receiving an optical signal from an optical transmission section of another optical transmission/reception module, converting the optical signal into an electric signal, and outputting a main signal and a control signal. The optical transmission/reception module 10 further comprises, at an optical reception section side: a pulse shaping section 15 for delaying a rising time Tr and a falling time Tf of the control signal; and a comparator 17 to which the control signal delayed by the pulse shaping section 15 and a predetermined reference voltage are inputted, and which adjusts the control signal to be a predetermined duty ratio. |
