  • a central bus; and

    a plurality of associated S/E bus modules connected with one another via the central bus, which S/E bus modules are adapted to receive a light signal communicated by a peripheral S/E module and pass it as a control signal to other S/E bus modules, and through said other S/E bus modules as a light signal to associated peripheral S/E modules;

    wherein the S/E bus modules shut off communication from the corresponding peripheral S/E module when they receive a light signal over the transmission pathway whose length is greater than a maximum admissible signal length.
