Abstract
A data bus arrangement and method whereby a plurality of nodes are connected to each other through a star coupler arrangement of a data bus. The data bus arrangement includes a logical decision gate which received a plurality of input electrical signals transmitted from a plurality of nodes with some of the signals being transmitted through an opto-electrical transducer to convert optical node signals to electrical signals output to the logical decision gate. The output of the logical decision gate is connected to each of the nodes with at least some of the nodes being connected through respected opto-electrical transducer to convert the electrical output signal from the respective logical decision gate to an optical signal fed to the nodes. In order to adjust the output signal from the logical decision gate, a signal preparation circuit provides pulse form adjustment in order to correspond to electrical input signals which enter the logical decision gate.
