Title:
POLISHING SHEET EQUIPPED WITH NANO-SILICA POLISHING PARTICLES, AND POLISHING METHOD AND MANUFACTURING METHOD FOR OPTICAL FIBER CONNECTOR USING POLISHING SHEET
Document Type and Number:
WIPO Patent Application WO/2017/098579
Kind Code:
A1
Abstract:
Provided are a polishing sheet capable of reducing recesses formed at a core of the end surface of an optical fiber, and a manufacturing method for an optical fiber connector using the polishing sheet. The manufacturing method for the optical fiber connector includes a step of the final polishing of an optical fiber ferrule assembly in which an optical fiber is polished and thereby protruding from the end surface of a ferrule, the protruding optical fiber having a recess in the tip end core formed by the polishing. During the final polishing step, the optical fiber having the recess in the core is inserted into an embedded portion of an embedded polishing sheet with the optical fiber ferrule assembly and the embedded polishing sheet disposed opposite each other; the optical fiber ferrule assembly and the embedded polishing sheet are moved relatively to each other in order to polish the optical fiber. In order to reduce the depth of the recess during the polishing, fibers constituting the embedded portion have silica grains with an average grain diameter from 0.01 μm to 0.1 μm adhered to the surface.
