PURPOSE:To attain high quality and high speed by making the electric phase shift of sender side and receiver side opposite to each other and making every electric path length from each electric connection pin at the sender side to each electric connection pin at the receiver side equal to each other. CONSTITUTION:When signals of in-phase enter electric connection pins A1-A5 at a sender side, the signal is inputted to each light emitting element 4 with a deviated phase for each channel and reaches a light receiving element 6. Since the phases of the signals are restored to in-phase at receiver side electric connection pins B1-B5, high quality and high speed transmission are attained even in the data transmission taking digital data of plural bits as the unit of information. |
