置。 A star coupler that distributes and outputs an optical signal input to any one port to all ports, an optical fiber that is connected to the port of this star coupler and transmits the optical signal, and multiple units that exchange data with each other. A station, and an optical fiber transmission/reception device that is connected to this station and converts the electrical signal from the station into an optical signal and outputs it to the optical fiber, and also converts the optical signal input from the optical fiber into an electrical signal and outputs it to the station. 1. An optical data transmission device comprising: an oscillator that oscillates at a predetermined frequency; and an electric cable that transmits an electric signal is connected between the oscillator and each station.
