ABSTRACT:
A master optical signal transmitter-receiver unit and slave optical signal transmitter-receiver units are connected in series for optical transmission by way of optical fibers. Each optical signal transmitter-receiver unit includes an optical connector for converting an optical signal to an electric signal and vice versa, an optical fiber switching circuit for switching the operation mode of the transmitter-receiver unit to thereby switch the data transmission direction, and a microcomputer. Each slave optical signal transmitter-receiver unit has a second optical connector connected to the first optical connector. The optical fiber switching circuits are under control of respective microcomputers. The microcomputer of each slave optical signal transmitter-receiver unit compares address data of the unit with address data received from the master optical signal transmitter-receiver unit. When the address data coincide with each other, the slave optical signal transmitter-receiver unit outputs data of itself toward the master optical signal transmitter-receiver unit or takes in data from the master optical signal transmitter-receiver unit.
