ABSTRACT:
A novel optical connector that includes the following: an optical connector ferrule which is capable of fixing optical fibers; optical fibers fixed onto the optical connector ferrule, such that the end surfaces of the optical fibers project beyond an end surface of the optical connector ferrule; an adhesive for fixing the optical fibers onto the optical connector ferrule; and a member whose Young's Modulus is less than that of the optical fiber and is provided to an area on the end surface of the optical connector ferrule surrounding, at a minimum, the projected portions of the optical fibers. And when the end surface of the optical connector is polished, the ends of the optical fibers are capable of projecting from the end surface of the optical connector ferrule, even if the end surface portion of the optical connector ferrule contains a filler, the hardness of which is less than that of the optical fibers.
