2075954 9111739 PCTABS00006 An optical fiber (F) having an axis therethrough and having a tip thereon comprising a first tapered region and a second adjacent tapered region (52A, 56A). The second tapered region (56A) terminates in an aspherical lens (60). Each of the tapered regions (52A, 56A) has a surface thereon. The surface of the first tapered region (52A) defines an angle with respect to the axis of the fiber (F) that lies in the range from about ten (10) to about thirty (30) degrees, while the surface of the second tapered region (56A) defines an angle with respect to the axis of the fiber that lies in the range from about thirty-five (35) to about sixty (60) degrees. The second tapered region (56A) is produced as a result of a jerking action imposed during the drawing of the fiber (F).
