Abstract
A method of polishing the end face of a ferrule on an optical connector comprises providing a polishing sheet containing abrasive grains and providing a polishing fluid containing abrasive grains having a hardness greater than that of the abrasive grains of the polishing sheet. The end face of the ferrule including an optical fiber is pressed against a surface of the polishing sheet while effecting relative movement between the ferrule and the polishing sheet and while supplying the polishing fluid onto the surface of the polishing sheet.
