Abstract
Official abstract text for this publication.
An embodiment of the present invention makes it possible provide a reinforcement structure which (i) makes it possible to reinforce an optical fiber in a simple manner and (ii) decreases the likelihood of degradation of a heat-shrinkable tube. A reinforcement structure (1) includes a tension-resistance member (13), a heat-shrinkable tube (16) which bundles a plurality of optical fibers (11, 12) and the tension-resistance member (13), and a radiator (15) which is in thermal contact with the tension-resistance member (13). The tension-resistance member (13) has a flat surface which faces respective circumferential surfaces of the plurality of optical fibers (11, 12).
First claim
Opening claim text (preview).
The invention claimed is: 1. A reinforcement structure for reinforcing a fusion splice point at which a plurality of optical fibers are fusion-spliced, the reinforcement structure comprising: a tension-resistance member; a heat-shrinkable tube which bundles the plurality of optical fibers and the tension-resistance member; and a radiator which is in thermal contact with the tension-resistance member, the tension-resistance member having a flat surface which faces respective circumferential surfaces of the plurality of optical fibers, wherein the heat-shrinkable tube is filled with a low-refractive-index resin whose refractive index is lower than a refractive index of cladding of each of the plurality of optical fibers. 2. The reinforcement structure according to claim 1 , wherein the tension-resistance member is a plate-like member whose upper surface faces the respective circumferential surfaces of the plurality of optical fibers. 3. The reinforcement structure according to claim 1 , wherein the flat surface of the tension-resistance member has a width which is greater than a diameter of each of the plurality of optical fibers. 4. The reinforcement structure according to claim 2 , wherein: the heat-shrinkable tube includes a cutout portion; and the tension-resistance member is in thermal contact with the radiator via a leg part which (i) is provided to a lower surface of the tension-resistance member in a region in which the tension-resistance member faces the fusion splice point and (ii) passes through the cutout portion. 5. The reinforcement structure according to claim 2 , wherein a groove for holding the plurality of optical fibers is formed in the upper surface of the tension-resistance member outside a jacket-removed section, such that in the jacket-removed section, the respective circumferential surfaces of the plurality of optical fibers are in contact with the upper surface of the tension-resistance member. 6. The reinforcement structure according to claim 1 , wherein the radiator is a water-cooled plate. 7. A reinforcement structure for reinforcing a fusion splice point at which a plurality of optical fibers are fusion-spliced, the reinforcement structure comprising: a tension-resistance member; a heat-shrinkable tube which bundles the plurality of optical fibers and the tension-resistance member; and a radiator which is in thermal contact with the tension-resistance member, wherein the tension-resistance member having a flat surface which faces respective circumferential surfaces of the plurality of optical fibers, the heat-shrinkable tube includes a cutout portion, and the tension-resistance member is in thermal contact with the radiator via a leg part which (i) is provided to a lower surface of the tension-resistance member in a region in which the tension-resistance member faces the fusion splice point and (ii) passes through the cutout portion.
