Claims

[Claims for Utility Model Registration] A photoelectric conversion unit that receives power light and an operation signal sent from the transmission end via an optical fiber, and a photoelectric conversion unit that is operated by the electric power obtained from the photoelectric conversion unit and that is related to the operation signal. A device comprising an electric circuit that generates an electric signal, and an operation section that inputs the signal from the electric circuit and generates a mechanical output related to the operation signal, wherein the optical fiber has a direction of propagation determined by a wavelength at both ends of the optical fiber. At the same time, the photoelectric conversion unit is configured with a separate photoelectric converter that receives each light separated by the splitter, and the power light and the operation signal are transmitted from the transmitting end to each other with different wavelengths. An optical actuator that transmits optical signals.
