Claims

[Claims for Utility Model Registration] (1) An optical fiber connector having a ferrule holding an optical fiber, comprising: a sleeve coaxially fixed to the proximal end of the ferrule; and a sleeve received within the sleeve. and a tubular member made of a thermoplastic resin, by heating a part of the sleeve and plastically deforming it inward while the optical fiber is inserted into the tubular member, the optical fiber is inserted into the optical fiber with the tubular member. an optical fiber connector, wherein the optical fiber connector is held within the sleeve. (2) An optical fiber connector having a ferrule holding an optical fiber, the sleeve coaxially fixed to the proximal end of the ferrule, and a tubular member made of a thermoplastic resin received within the sleeve. An optical fiber connector, characterized in that the optical fiber is welded into the sleeve with the tubular member by heating the sleeve with the optical fiber inserted through the tubular member. .
