ABSTRACT:
A fiber optic cable connector is comprised of two ferrules, a collar member, and a connection sleeve. First and second ferrules each have an internal bore to receive the end of fiber optic cable bundles together with a suitable bonding material for securing the fiber optic cable bundles. The terminal ends of the fiber optic cable bundles are ground and polished substantially optically flat. A first ferrule has external threads on a portion at its terminal end. The collar member is internally threaded and dimensioned to engage over the external threads of the first ferrule, and has a cylindrical portion coaxially extending beyond the terminal end of the first ferrule effectively forming a cylindrical recess. A second ferrule has a cylindrical embossment dimensioned to be received within the coaxially extending portion of the collar member for aligning the two fiber optic cable bundles. External threads on the outermost portion of the second ferrule at its terminal end are engaged by the internal threads of a connection sleeve which has an inwardly disposed flange at its other end dimensioned to bear upon an end of the collar member for drawing the two terminal ends of the fiber optic cable bundles together in an aligned assembly.
