摘要： A method of and an apparatus for coupling ends of first and second multicore coated optical fibers each having multiple optical fibers integrally covered with a coating. The method includes a clamping step of setting the first and second multicore coated optical fibers in first and second clamp members, respectively, a cutting step of cutting off exposed fiber ends of the first and second multicore coated optical fibers and a coupling step of coupling cut end faces of the optical fibers of the first and second multicore coated optical fibers such that the cutting step and the coupling step are performed without detaching the first and second multicore coated optical fibers from the first and second clamp members, respectively.

摘要： A molding die 1 is constituted by an upper die 1a and a lower die 1b which are made of a material transparent to an ultraviolet light, and has a cavity 3 constituted by grooves 2c, 2d, whereas a resin injection gate 4 and a resin exit gate 7 are provided so as to communicate with the cavity 3. A junction of an optical fiber 10 is inserted into the cavity 3. A UV-curable resin is injected into the cavity 3 surrounding an exposing portion of the glass optical fiber 11 from the resin injection gate 4 positioned at one of coating ends of the optical fiber 10, whereas a part thereof is discharged from the resin exit gate 7 positioned at the other coating end. The ultraviolet light is emitted through the lower die 1b so as to cure the resin, thereby forming a reinforcement resin coating. As a consequence, bubbles can be prevented from occurring due to the residual air within the reinforcement resin coating in the junction of the optical fiber 10.

摘要： An apparatus for separating a ribbon-coated multicore optical fiber at a plurality of positions at once, which is excellent in separating operation. This apparatus is an apparatus for separating a ribbon-coated multicore optical fiber, in which a number of single-core fibers are arranged in parallel, into a plurality of fibers. This apparatus comprises a first cutting member in which a plurality of sets of arc faces opposed to each other by way of a through path for inserting the ribbon-coated multicore optical fiber are disposed along the through path, while the arc faces in the respective sets extend from one side section of the through path halfway through the width direction of the through path; a second cutting member having a plurality of arc faces which continuously extend to and are adapted to join with the respective arc faces of the first cutting member in the width direction of the through path; and guide members which are respectively disposed at both end positions of the through path so as to position the ribbon-coated multicore optical fiber inserted into the through path. The first and second cutting members are relatively movable to each other in the direction in which the arc faces are opposed to each other.

摘要： Disclosed is an optical connector connecting apparatus. In the apparatus, a plurality of fixed optical connectors are mounted on a fixed member in a lined-up manner. An optical connector containing member having a movable optical connector mounted thereon is supported on a support member through a small-diameter beam. A moving plate mounted on a base supports the support member, and the movable optical connector is moved in X-axis, Y-axis and Z-axis directions so as to be connected to the fixed optical connector. Therefore, a position deviation at the time of the connection is corrected by the flexing of the small-diameter beam so that fine-positioning is unnecessary.
