Abstract
An optical subassembly (OSA), in accordance with the present invention, includes a housing, which may be substantially rectangular, the OSA includes a first end portion and a second end portion oppositely disposed from the first end portion. The first end portion forms a bore configured and dimensioned to receive a ferrule having an optical fiber therein. The bore is adjacent to a ferrule stop which is integrally formed in the housing. A lens is integrally formed with the housing. The lens has a planar surface and a convex surface opposite the planar surface. The planar surface of the lens is substantially parallel to and set in from the ferrule stop to prevent contact between the ferrule and the planar surface. The optical device, the lens, and the bore which accepts the ferrule are all in optical alignment.
