Method and system for optimizing power carrier signal indicated by optical signal

The invention provides a method for optimizing a power line carrier signal indicated by an optical signal, which comprises the following steps of: coupling a constructed transition source with a power line so as to form a carrier signal by utilizing a carrier signal output by a user side and an optical signal to carry out convolution processing on the carrier signal and a current signal in the power line, and coupling the carrier signal into the power line for transmission; and S3, transmitting the optical signal and the power line current signal in parallel in a communication optical cable parallel to the power line, carrying out deconvolution processing at a test end, and carrying out deconvolution operation to analyze a carrier signal at the user end, namely, obtaining an electric meter and/or a concentrator in a power line carrier communication system at the user end. Or original carrier signals sent by power carrier communication units STA and CCO in the power carrier test system. Anti-interference of po
