ABSTRACT:
A method for manufacturing a ferrule for use with an optical fiber connector comprises providing a ferrule blank having a hole for insertion of an optical fiber therethrough between end surfaces of the ferrule blank. A rough grinding operation is performed on the outside diameter of the ferrule blank. Thereafter, the hole of the ferrule blank is polished based on the outside diameter of the ferrule blank which has been subjected to the rough grinding operation. The outside diameter of the ferrule blank is then subjected to a finish grinding operation using a both-center supporting method by bringing a center jig to abut the end surfaces of the ferrule blank and supporting the ferrule blank with the center jig from the end surfaces of the ferrule blank.
