An optical fiber ferrule assembly is provided which enable preventing the optical fiber from tilting and misalignment with regard to the ferrule. An optical fiber ferrule assembly which forms a part of an optical connector includes an optical fiber and a ferrule made of resin. The optical fiber integrated with the ferrule by embedding an end of the optical fiber into the ferrule via insert molding. A plurality of holes are formed in the ferrule, wherein the holes extend from an outer surface of the ferrule to an outer circumferential surface of the optical fiber. These holes are formed by disposing a plurality of pins for positioning the optical fiber into a mold for the ferrule.

A ferrule mold having a reverse-image of a through-hole array for optical fibers is formed. A non-polymeric ferrule material is deposited in the reverse-image mold, followed by removing the mold to create a multi-fiber connector ferrule having at least two fiber through-holes. An optical fiber is inserted in each through-hole until each fiber endface is positioned approximately even with a connection surface of the ferrule. A fiber recess for each of the optical fibers is formed such that each fiber is recessed from the multi-fiber ferrule connection surface by a distance of at least 0.1 micron. The recess may be formed by differential polishing of the non-polymeric ferrule and endfaces of the optical fibers. Alternatively, a layer of spacer material may be deposited over the multi-fiber ferrule connection surface. An antireflection coating is deposited over the ends of the recessed fibers.

An adaptor with a built-in shutter member for optical connector including a body, a shutter, and an elastic member is provided. The body has a receiving space. The shutter is movably assembled to the body to shield or expose the receiving space. An optical connector is suited for pushing away the shutter to enter the receiving space to be connected to the body. The shutter has a step structure such that a gap is maintained between the shutter and the optical connector. The elastic member is disposed in the body and located on a moving path of the shutter. The shutter deforms the elastic member when the optical connector pushes away the shutter, and the elastic member drives the shutter to be restored when the optical connector leaves the receiving space.
