PROBLEM TO BE SOLVED: To obtain a correct output voltage by converting the optical signal of each color (wavelength) to 100% voltage. SOLUTION: The optical transmission device is provided with a multiplexer 1 to multiplex a plurality of optical signals having different wavelengths to one optical signal, a branching filter 3 to separate an optical signal outputted from the multiplexer 1 and transmitted through an optical cable 2 into a plurality of chrominance signals of an original wavelength for converting it into an electric signal, and an arithmetic and logic unit 4 to receive a voltage outputted from the branching filter 3 for calculating a correct output voltage. |
