ABSTRACT:
A data transmission system comprising a plurality of data processing units connected to each other by optical fiber. Each data processing unit comprises optical/electrical converter means for converting an optical signal from the preceding data processing unit through the optical fiber to an electrical signal, electrical/optical converter means for converting an electrical signal to be sent to the succeeding data processing unit to an optical signal, a data receiving unit for receiving the converted electrical signal, means for determining whether or not the received signal was sent from the local data processing means, and gate means connected between the optical/electrical converter means and the electrical/optical converter means, the gate means being closed when the local data processing means performs data transmission and opened for alternative data receiving/passing.
