Abstract
An optical connector ferrule is equipped with a fiber insertion hole composed of an introductory hole, an intermediate hole, and minute holes. The introductory hole has a sectional area, which allows insertion of the coated portions of optical fibers. The intermediate hole has a sectional area which does not allow insertion of the coated portions of the optical fibers but which allows insertion of bare fibers exposed in front of the coated portions. Each of the minute holes has a sectional area, which allows individual insertion of each of the forward end portions of the bare fibers inserted into the intermediate hole. Thus, the insertion length of the optical fibers in the fiber insertion hole is uniquely determined. In particular, the insertion length of the coated portions can be set a predetermined length easily and reliably.
