摘要：PURPOSE:To connect an optical circuit with high efficiency with use of an optical fiber, by providing three sets of converters combining a photoelectric converter and an electrooptic converter respectively and a logical circuit which transmits the received signal to other two sets of electrooptic converters. CONSTITUTION:The optical information fed from the left side via an optical fiber 41 is applied with electrooptic conversion 52 via an OR circuit 54 after applied with photoelectric conversion 47 and then sent to another circuit network in the form of optical information again. This optical information is supplied to an optical fiber 44 of a main track of the circuit network via an OR circuit 56 and an electrooptic conversion element 50. In the same way, the optical information sent via an optical fiber 43 applied with same conversion 52 via the circuit 54 after applied with photoelectric conversion 49 and applied with electrooptic conversion 48 via an OR circuit 55 to be sent o another circuit network via optical fibers 46 and 42 as the optical information again. While the information transmitted to another circuit network via the fiber 46 is fed back a circuit network coupler 40 again via an optical fiber 45.
