Abstract
In an optical connector ferrule comprising an insertion opening through which one end of a coated optical fiber with the coating removed is inserted. A guide groove is provided for guiding the bare fiber of the optical fiber. A fiber hole is provided for inserting therein the bare fibers guided by the guide groove. An injection port is provided for injecting therein adhesive for securing the coated optical fiber to the ferrule. Guide surfaces are provided for guiding the bare fiber to the guide grooves at sides of the guide groove. In the similar optical connector ferrule, there is provided an enlarged portion extending forwardly from a leading edge of the injection port in a fiber inserting direction and reaching a filling space into which the adhesive is filled. Further, a ceiling surface of the enlarged portion is inclined downwardly forwardly from the injection port.
