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 1):
A method of manufacturing an optical fiber connector having optical fibers attached to a ferrule comprising:\n polishing to finish an optical fiber ferrule assembly of which optical fibers have recesses at their tip cores, the optical fibers having been made to protrude from an end face of the ferrule through a polishing, the recesses having been formed by the polishing; wherein the polishing to finish is performed by moving the optical fiber ferrule assembly and a flocked polishing sheet relative to each other while the optical fiber ferrule assembly and the flocked polishing sheet are disposed opposite to each other and while the optical fibers having the core recesses are inserted into a flocked portion of the flocked polishing sheet, the fibers which constitute the flocked portion having silica particles attached to the surfaces of the fibers so as to reduce the depths of the recesses in the polishing to finish, the silica particles having an average particle diameter in the range of 0.01 \u03bcm to 0.1 \u03bcm.
