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.

摘要： A method for splicing coated optical fibers. The outer coating layer of two coated optical fiber ends to be joined is removed from respective end portions thereof. The inner optical fibers so exposed are then coated with a layer of UV-curable resin. After the resin layer has been hardened by irradiating it with ultraviolet radiation, the coated portion may be securely clamped without fear of damaging the optical fibers. The clamped end portions may then be moved toward one another in order that they may be fused together.

摘要： An exposed part of at least one of two optical fibers with different mode field distributions to be fusion spliced is heated by a burner, to thereby continuously vary its mode field distribution in the longitudinal direction of the optical fiber, and the exposed end part of at least one of the optical fibers is cleaved so that the mode field distributions at the splice end faces of the two optical fibers to be fusion spliced are substantially coincident with each other in configuration, the two optical fibers are fusion spliced, whereby low splice loss is realized. Thereafter, the heated portion of the optical fiber is subjected to a surface treatment by etching process using a hydrofluoric acid solution, whereby a deterioration of its mechanical strength is prevented. Surface tension of the acid causes the rim of the container to stand up.

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.

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 movable relative to each other in the direction in which the arc faces are opposed to each other.
