PROBLEM TO BE SOLVED: To provide an optical and radio integrated transmission system, capable of performing high quality communications by preventing the interference of an optical signal. SOLUTION: This optical and radio integrated transmission system is provided with laser diodes 204, 205 and 206, having different wavelengths of the optical signals in each radio equipment, performs modulation of the optical signals as an optical signal of a plurality of wavelengths by electro-optical(E/O) converters 207, 208 and 209 and subsequently, synthesizes the optical signals by a synthesizer 210 in the case of modulating the optical signal by radio signals from a plurality of radio equipment 201, 202 and 203 in a radio base station in the case of down link from the radio base station to a mobile station. |
