Abstract
A method of making an inlet cone at one of the ends of a connection endpiece for optical fibers, the endpiece being in the form of a cylindrical rod of outside diameter D and including an internal capillary of diameter d.sub.i, the method consisting in providing the end of the connection endpiece with a guide part constituted by a cylindrical body having formed therein: firstly a cylindrical bore of diameter substantially equal to the diameter D of the endpiece, which bore is delimited inside the cylindrical body by a wall constituting an abutment for the end of the endpiece when the endpiece is inserted into the bore; and secondly a guide hole having at least one tapering portion opening to the outside of the cylindrical body with a diameter that is greater than the diameter d.sub.i, and opening into the cylindrical bore at the capillary with a diameter which is substantially equal to the diameter d.sub.i of the capillary. The invention is applicable both to monomode and to multimode optical fibers.
