Abstract
A ferrule with optical fiber is held to a ferrule holder. The ferrule is made of a material with 0.5˜2 times the wearing speed characteristic in comparison with a quartz glass. The ferrule holder comprises a polishing plate which has an elastic module equivalent to 70˜95 degrees of rubber hardness in a state of adhering a polishing sheet thereon. The ferrule holder is made to be self-supported on a polishing table in a manner such that the end face of the ferrule with optical fiber is in contact with the polishing sheet. The ferrule holder is made to manually move on the polishing table by a predetermined distance in the horizontal direction to slide the end face of the ferrule with optical fiber on the polishing sheet, thereby the end face of the ferrule with optical fiber is polished to a spherical convex surface centered on the optical fiber.
