Optical fiber connector and method for its manufacture
First Claim
1. An optical fiber connector for joining an optical fiber to an optical fiber in an opposing connector, comprising a ferrule and an optical fiber surrounded by the ferrule, with the end face of the fiber being inclined with respect to a plane which is perpendicular to the longitudinal axis of the fiber and produced by a rotating polishing tool whose axis of rotation is inclined to said axis of said fiber, the ferrule having an end face comprising a portion projecting over the end face of the fiber in the direction of the fiber axis, but not being arranged in the same plane as the fiber end face, with the projecting portion forming a bearing surface for said opposing connector such that he two connectors can be brought into contact with each other and the opposing fiber end faces have a distance from each other when the connectors are in contact.

Abstract
An optical fiber connector for joining optical fibers comprises a cylindrical ferrule (1) with a fiber (20) arranged along the axis of the ferrule and with an end face (23) of the fiber (20) inclined with respect to a plane perpendicular to the fiber axis (10). The fiber end face (23) is set back a predetermined distance from a projecting surface (22) of the ferrule end face. This projecting surface (22) acts as a bearing surface for an opposite connector so that two connectors can be brought into physical contact whereby a well-defined distance between the fiber end faces is maintained. In the connected state, the fiber end faces of two opposite connectors are arranged parallel to each other, thus ensuring high return loss of the connector system. The connector can easily be manufactured by a polishing process from a standard connector having ferrule and fiber end faces parallel to the fiber axis. (FIG. 2a: side view; FIG. 2c: top view).
