摘要： The invention is directed to an optical connector in which a length of an optical fiber 5 projects from a connection end surface (16) of a ferrule (1) is accurately set, a method of and a fixture for setting the projection length of the optical fiber. A recess surface (33) is formed in a ferrule receiving surface (32). A depth of the recess surface (33) is equal to a length an optical fiber (5) projects from the connection end surface (16) of the ferrule (1). The ferrule (1) is held by ferrule holding members (35a) and (35b), so that the ferrule (1) is abutted against the ferrule receiving surface (32) by the urging force of compression springs (36). Through the ferrule (1), an optical fiber cored line (3) is projected from the connection end surface (16) of the ferrule (1) and abutted against the recess surface (33). The optical fiber cored line (3) is held by a cored line holding member (41), the cored line holding member (41) is urged toward the ferrule receiving surface (32) by the urging force of compression springs (42), and a tip of the optical fiber (5) is brought into a pressure contact with the recess surface (33). In this condition, an adhesive agent is injected into an adhesive injecting hole (43) of the ferrule (1) so that the optical fiber (5) is fixedly bonded to the ferrule (1), thereby obtaining an optical connector in which the optical fiber (5) projects a predetermined length from the connection end surface (16) of the ferrule (1).

摘要： A short optical fiber 2 is incorporated in a ferrule 1 having a polished front end, so as to be projected from the rear end of the ferrule. In a base member 3 in which the short optical fiber is to be fitted into a hole 3b, a V-groove 3d to which the glass portion of an optical fiber is to be fixed, and a V-groove 3e to which the coated portion is to be fixed are formed. A cover member 4 is placed on the base member. The base member 3 and the cover member 4 are clamped by clamp members 5a and 5b and the base member 3 presses to V-grooves. Wedges which are not shown are pressingly inserted between recessed 3g and 4c, and 3h and 4d, and an optical fiber 10 is inserted from the rear portion. Thereafter, the wedges are detached and the optical connector is attached to the terminal of the optical fiber 10.

摘要： In an optical cable according to the present invention, a grooved spacer has a plurality of grooves in its circumference, and the cutting direction of the grooves is inverted at predetermined periods. Optical fibers are received in the respective grooves. On the circumference of the grooved spacer, a linear member is provided around the grooved spacer along the longitudinal direction of the optical cable at a predetermined period. The linear member is fixed to the grooved spacer by welding or bonding in the portions where they touch the outer circumferences of the grooved spacer so as to restrain the optical fibers. The linear member restraining the optical fiber to be taken out are cut in positions above the groove in which the optical fiber is received so that the required optical fiber can be taken out.
