Abstract of the Disclosure A device for connecting optical fibers is formed by inserting one or more fibers into at least one end of a capillary tube. The bore is tapered to facilitate fiber insertion. To taper the end of a bore, the tube is rotated about its longitudinal axis while a first narrow stream of abrasive particles is directed onto the tube end. The axis of the first stream is located off the axis of the tube bore, thereby forming a taper that is spherical rather than conical. A second stream, the axis of which is coaxial with the bore, is then directed onto the tube end to remove that portion of the tapered aperture adjacent the bore, thereby forming a more funnel-shaped aperture.
