description The invention relates to an RFOG optical receiver circuit, and belongs to the technical field of radio and television RFOG transmission. The system comprises eight paths of input optical signals, eight groups of optical receiver circuits and eight paths of mixers; wherein the eight paths of input optical signals are respectively connected with the eight groups of optical receiver circuits throughsignal lines, the eight groups of optical receiver circuits are respectively connected with the eight paths of mixers through signal lines, and the eight paths of mixers are connected with the radio frequency output port through signal lines, so that a controlled closed-loop circuit is formed. One group of optical receiver circuits comprises a first path of input optical signal, a photoelectric conversion circuit, a radio frequency amplification circuit, a high-speed operational amplifier comparison circuit, a field effect switch circuit and a path of mixer. According to the invention, eight-path mixed output, high-sp
