は大きく、配線時の引張り強度は強いが可撓性が低い。In general, the cladding layer of a bulk fiber has a lower refractive index than the core layer, so that light incident from one end is propagated through the core layer, totally reflected at the interface between the printing plate and the cladding layer, and then emitted from the other end. Became ℃・ru. The light propagating through the bulk fiber suffers reflection loss due to non-uniform flatness of the interface between the core layer and cladding layer and manufacturing variations, and the propagation loss increases in proportion to the number of reflections. A thick bulk fiber has fewer reflections than a thin bulk fiber trap, so there is less propagation loss. In addition, bulk fibers with a large diameter have high breaking strength and breaking elongation, and have high tensile strength during wiring, but low flexibility.

ある。According to the present invention, the light receiving side is formed by a bundle fiber that bundles bulk fibers with a large diameter, and the output side is formed by a bundle fiber that bundles bulk fibers that are smaller in diameter than the bulk fibers on the light receiving side. The propagation loss due to reflection loss in each bulk fiber on the long receiving side is small, increasing optical efficiency, and each bulk fiber on the output side has a small diameter, making it highly flexible and easy to control distribution. The bundle fiber on the receiving side has a large diameter, so the number of fibers can be reduced, making it cheaper. Furthermore, the large diameter has a large breaking strength LL, high breaking elongation, and high tensile strength during distribution, so it is easy to install wiring. It is.
