Multiple-core optical connector and its manufacturing method

摘要

The invention relates to a multiple-core optical connector and its manufacturing method, wherein the end faces of optical fibers are made free from any damage. Optical fibers (12) are inserted into optical fiber insertion holes (2) of a ferrule (1) of a multiple-core connector, which is equipped with a plurality of optical fiber insertion holes (2) and made of plastic resin, and are fixed therein with an adhesive agent. Fitting pin holes (3) for axial alignment are constructed of a hole of a sleeve (5) made of a material, the hardness of which is higher than that of the plastic resin and optical fibers (12). If the connection end faces of the ferrule (1) for multiple-core optical connector are buffing-finished by using free abrasive grains, since the end face of the sleeve (5) having a higher hardness is less ground than the optical fibers (12), the end face of the sleeve (5) is formed to protrude from the connection end face of the optical fibers (12).
