The optical fibers are mounted on a jig so that their end faces are pressed against a polishing film attached to a rotary disk. The polishing film is made of a flexible (or cushionable) soft material having a Shore hardness of 10 through 100, such as synthetic rubber. The jig performs an orbital motion without rotation on its own axis. | |
