光信号送受信装置。 An optical transmitting circuit and an optical receiving circuit are housed in the same housing, and the optical transmitting circuit opens and closes a light emitting element that emits light upon application of a first DC voltage and a current flowing through the light emitting element. The light receiving circuit includes a first circuit breaker and a third circuit breaker which are connected to each other and are closed when a transmission signal is input. A second circuit switch that becomes open when the transmission signal is input, and a waveform shaping circuit that detects the energized current and outputs a rectangular waveform reception signal according to the energized current are connected to the second DC voltage. The circuit is connected in series from the positive electrode to the negative electrode, and the first circuit breaker and the third circuit breaker are connected between the light emitting element and the positive electrode of the first DC voltage and between the light emitting element and the positive electrode of the first DC voltage. and a negative electrode of the first DC voltage, respectively.
