1. An optical bus transmission system for transmitting data between a master station and a plurality of slave stations by means of an optical bus;

  • said master station being provided with a means for transmitting a serial optical signal in a transmission format consisting of a synchronizing signal, address information and data information comprising an output data part and an input data part;

    each of said slave stations being provided with;

    a means for serial to parallel converting the serial signal received from said master station;

    a means for parallel to serial converting serial input data information stored in said slave station;

    a detecting means for detecting a coincidence of an address set previously in said slave station with the received address information from the master station;

    a transmitting means for transmitting a serial optical signal at least partially corresponding to the received serial signal;

    a switching means for switching said transmitting means so that said input data information is transmitted as the input data part of the data information in the transmission format of the transmitted serial optical signal from said slave station when a coincidence of addresses is detected, and the received serial signal is transmitted as the transmitted serial optical signal in the absence of a detection of a coincidence of addresses;

    and said transmitting means includes a means for controlling an optical transmission time of information bits so as to generate a vacant transmission time among the slave stations.
