The proposed optoelectronic device for transmitting and receiving discrete signals from distributed objects contains an optical radiation source and an RC oscillator with constant frequency, which are installed at each monitored object, and a photodetector and a signal selector that are installed at the side of signal reception. Additionally, the device contains, at each monitored object, a test signal generator. The test signal generator contains two field-effect transistors with combined sources, which constitute an analogue of a double-base diode, and two temperature sensors with a positive resistance temperature coefficient. The drain of the n-channel field-effect transistor constitutes the cathode of an analogue of a double-base diode. The drain of the p-channel field-effect transistor constitutes the anode of an analogue of a double-base diode.
