Abstract
One or more glass or other brittle fiber ends are prepared by first embedding the fiber in epoxy or other plastic and then slicing the plastic and the fiber a first time to produce an oblique end face and a second time to produce an end face exhibiting intersecting planes. The slicing is continued with successive advancements of the slicing of approximately one thousandth of an inch to produce a squared end. The technique is applicable to fiber end preparation of single fibers and plural fibers as in optical fiber tapes and cables.
