PROBLEM TO BE SOLVED: To reduce the number of wiring between equipment performing signal processing and equipment performing transmitting and receiving radio signals, in a base station of a mobile communication system. SOLUTION: An optical bus 30 performs optical bus connection between each board of a signal processing part 22 and each board of a transmitting and receiving part 40, and transmits optical signals which are outputted from each of the boards of the signal processing part 22 to the optical bus 30, to each of the boards of the transmitting and receiving part 40 through non-block manner. The optical bus 30, on the contrary, transmits optical signals which are outputted from each of the substrates of the transmitting and receiving part 40 to the optical bus 30, to each of the boards of the signal processing part 22 in non-block manner. |
