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).
