<p>A device for connecting optical fibers is formed by inserting one or more fibers into at least one end of a capillary tube (10). The bore (12) is tapered to facilitate fiber insertion. To taper the end of a bore, the tube (10) is rotated about its longitudinal axis (11) while a first narrow stream (24) of abrasive particles is directed onto the tube end (22). The axis (25) of the first stream (24) is located off the axis (11) of the tube bore, thereby forming a taper that is spherical rather than conical. A second stream (36), the axis of which is coaxial with the bore, is then directed onto the tube end (22) to remove that portion of the tapered aperture adjacent the bore (12), thereby forming a more funnel-shaped aperture.</p> |
