PROBLEM TO BE SOLVED: To compactly realize many channels of optical fiber in a small space made of plastics optical fiber by inserting a positioning pin provided on the element side in the hollow part of fiber, holding the diameter of a hollow part to be constant, and simultaneously with it positioning the center of the fiber. SOLUTION: A multicore hollow fiber having a hollow part on the center part is used, and a plurality of signal channels are formed. In this case, it is constituted of light emitting elements 11, a positioning pin 12, a multicore hollow fiber 10, a hollow part 2 formed on the center part, and territories corresponding to the diameter of the light emitting elements 11, namely signal channels 3. In the connecting part of at least one side of light emitting elements 11 and the light receiving elements and the fiber 10, the positioning pin 12 provided on the element 11 side is inserted in the hollow part 2 of the fiber 10, and simultaneously with holding the diameter of the hollow part 2 constant, the center of the fiber 10 is aligned. In this case, it is necessary for wiring corresponding to twist of the multicore hollow fiber.
