ABSTRACT:
The axial positions of two or more fibers are simultaneously controlled in three grinding or polishing stages. The fibers (72) are first ground flush with the guide (120) in which they are housed. The fiber ends and faces of the guides are then ground flat and square. The fibers are thereafter polished to their optical quality and required length. The tool for accomplishing these steps includes a retainer (74) which holds the assembly (73) of fiber optic ferrules (70) and their optical fibers (72) therein at a tool surface (16). This tool surface is protected by a guard (18) from being too rapidly ground away while the fibers and fiber/guide combinations are ground flush with the surface. The surface and its retained guides and fibers are then axially moved to an unprotected position (FIG. 3) so that the surfaces and the fibers within their ferrules may be polished on a suitable polishing wheel or similar device.
