摘要:
An optical connector has a ferrule for accommodating an optical fiber. The ferrule includes a glass capillary and a coating. The glass capillary is formed at the distal end portion of the ferrule and is inserted in a ceramic sleeve that performs optical connection. The glass cylinder has a first through hole at the central axis portion thereof to accommodate a bare optical fiber. The coating is made of a material having a higher hardness than that of the sleeve, and coats an entire outer circumferential surface of the glass capillary. A method of manufacturing an optical connector is also disclosed.
