Abstract
An optical connector ferrule according to an embodiment includes an MT ferrule, and a spacer mounted on an optical end surface of the MT ferrule and having a guide hole into which a guide pin is inserted. The spacer has a contact surface that contacting the counterpart connector and a recess surrounded by the contact surface. The spacer includes a lens part exposed on a bottom surface of the recess and optically coupled to the optical end surface of the MT ferrule and a base part that retains the lens part by surrounding the lens part. The material of the lens part and the material of the base part are different from each other, and the difference between the linear expansion coefficient of the base part and the linear expansion coefficient of the MT ferrule is 0.5×10/° C. or less.
