Abstract
Expanded beam fiber optic connectors for establishing an aligned connection between an end of an optical fiber and a ball lens. A housing includes a bore and is made of a compressible material for secure press fit of components within the bore, including the ball lens. A ferrule at the end of the optical fiber supports the optical fiber. In one embodiment, a section of optical fiber is coaxially centered within and supported by a single piece fiber stub with stepped outside diameters defining a press fit end and a secondary connection end, with a butt joint between the other end of the section of optical fiber and the end of the optical fiber being connected. In another embodiment, the ferrule is inserted within a longitudinally extending sleeve having an outside diameter sized for being press fit within the bore and an inside diameter sized for receiving the ferrule.
