Abstract:
A polishing sheet capable of reducing recesses formed at the core of the end surface of an optical fiber, and a manufacturing method for an optical fiber connector using the polishing sheet are provided. The method includes a step of the final polishing of an optical fiber ferrule assembly in which an optical fiber protrudes from the end surface of a ferrule, the protruding optical fiber having a recess in the tip end core. During the final polishing step, the optical fiber having the recess in the core is inserted into a flocked portion of a flocked polishing sheet. The optical fiber ferrule assembly and the flocked polishing sheet are disposed opposite one another and moved relatively to each other in order to polish the optical fiber. Fibers constituting the flocked portion have silica particles with an average particle diameter from 0.01 μm to 0.1 μm adhered to the surface.

Claim (Index 2):
A method of manufacturing an optical fiber connector as set forth in  claim 1 ,\n wherein the recesses have been formed by a first polishing to polish an optical fiber ferrule assembly having a flat end face so that the optical fibers protrude, and by a second polishing to polish the protruding optical fibers; and wherein the depths of the recesses are reduced by the polishing to finish as compared to those after the first or second polishing.
