Optical connector ferrule and optical connection structure

Abstract

An optical connector ferrule comprises a body and a spacer. The body has a flat ferrule end surface facing a corresponding optical connector, and an optical fiber retaining hole opened in the ferrule end surface, an optical fiber being inserted and retained in the optical fiber retaining hole. The spacer is joined to the body, and at least a portion of the spacer is disposed on the ferrule end surface. The spacer defines an interval between the ferrule end surface and the corresponding optical connector, and includes an opening that allows an optical path extending from the optical fiber to pass therethrough.
