Abstract: An optical fiber connector at least comprising an optical fiber ferrule capable of fixing an optical fiber, and an optical fiber fixed in the optical fiber ferrule, a pair of the optical fiber connectors being used such that their respective end faces are opposed to each other to connect the optical fibers; wherein the core portion at the end of the optical fiber is recessed inwardly of the end face of the cladding, and the end face of the optical fiber is recessed inwardly of the end face of the ferrule; whereby reduction in variations is achieved in connection loss occurring depending on whether PC coupling takes place or not, and variations in connection loss associated with multiple reflection.
