The utility model provides a system of testing an intelligent equipment optical power receiving sensitivity. The system comprises an optical signal generation apparatus, intelligent equipment, response monitoring equipment and an optical power meter, wherein the optical signal generation apparatus sends a GOOSE message to tested intelligent equipment through an optical fiber link and a light attenuation meter on a light link; the intelligent equipment outputs a level signal according to the GOOSE message; the response monitoring equipment detects the level signal and sends an instruction signal to the optical signal generation apparatus; the optical signal generation apparatus adjusts optical power of the light attenuation meter according to the instruction signal and sends the GOOSE message to a light port to be tested of the tested intelligent equipment through the optical fiber link and the adjusted light attenuation meter; the optical power meter measures the optical power which enters into the tested intelligent equipment. Accurate measurement to the optical power receiving sensitivity of the intelligent equipment is realized.
