Abstract: A fiber optic connector assembly for terminating and connecting fiber optic cables. The assembly comprises a housing, which housing comprises a pair of separable portions which may be locked together, with each of the housings carrying a plurality of fiber optic connector halves. The fiber optic connector halves, when connected, comprise a pair of ferrules, each having a bore proportioned to receive the stripped end of one of the cables having an exposed fiber optic core end. The ferrules have outer walls that are parallel to the axis of the bore. An outer sleeve is present defining a tubular portion for snug contact with the ferrule outer walls while the ferrules are in end-abutting relation. The relative transverse positioning of the ferrules in an abutting relation is determined by the position and shape of the tubular portion and its engagement with the ferrule outer walls. Thus, fiber optic core ends within the abutting ferrules may abut each other with precisely controlled transverse alignment.
