Abstract
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 …
