Patent ID: 10451816

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.
