Abstract
The axial position of the fiber is controlled in three grinding or polishing stages. The fiber (72) is first ground flush with the guide (120) in which it is housed. The fiber end and face of the guide are then ground flat and square. The fiber is thereafter polished to its optical quality and required length. The tool for accomplishing these steps includes a retainer (74) which holds the fiber optic ferrule (70) and its optical fiber (72) therein at a tool surface (16). This tool surface is protected by a guard (18) from being too rapidly ground away while the fiber and fiber/guide combination are ground flush with the surface. The surface and its retailed guide and fiber are then moved to an unprotected position (FIG. 3) so that the surface and the fiber within its ferrule may be polished on a suitable polishing wheel or similar device.
