ABSTRACT:
A plastic optical fiber end surfaces processing method is disclosed which allows formation of not only a convex semi-spherical surface but also of an arbitrary profile such as a concave semi-spherical surface. In addition, an apparatus for use in the method, a cutter for the method, and a plastic optical fiber connection method are disclosed. At least the core portion of the end surface of a plastic optical fiber is cut into a semi-spherical surface by a semi-circular cutter, which is of a convex or a concave shape. This cutter is inserted into a through-hole of a holder and rotates therein. The plastic optical fiber is inserted into the through-hole of this holder, and end surface processing is effected by the rotating cutter.
