Abstract
Disclosed is an optical fiber connector for ultra high-speed communication which can be produced by easy machining procedures and which enables stable and efficient transmission. The connector comprises a columnar ferrule having a through hole in which a connection end portion of an optical fiber is retained, a tapered portion serving as a connection guide and assuming a conical face formed at the and of the ferrule, and a convex spherical face formed at the end of the tapered portion. An intersection of the convex spherical face and the axis of the ferrule forms a reference abutment point. A straight line passing through this reference abutment point and angled with respect to the ferrule axis forms a reference normal intersecting orthogonal to the convex spherical face. When the cone axis of the tapered portion is within a vertical cross section taken along the ferrule axis and containing the reference normal and an abutment line intersecting with the reference normal at the reference abutment point, the position of the tapered portion is such that a central point of a segment defined on the abutment line as being surrounded by the conical face of the tapered portion may locate on the ferrule axis.
