ABSTRACT:
The fiber optic cable adapter spool is formed to be retained within an end plate assembly of a wire cable splice closure assembly. The adapter spool provides a cable entrance port capable of supporting an optical fiber cable in conventional telecommunication applications. The fiber optic cable is wrapped with a high coefficient of friction, adhesively-backed tape and a layer of mastic sealant before placed in the cable entrance port. The cable entrance port has two sets of annular gripping teeth and a plurality of annular sealing ribs located between the sets of annular gripping teeth. Once the cable has been placed into a cable entrance port, the adapter spool is contracted to cause the two sets of annular gripping teeth to exert radial pressure into either end of the wrapped portion of the cable. Similarly, during contraction, the layer of mastic sealant around the tape, positioned between the gripping teeth, cooperates with the sealing ribs between the gripping teeth to form a seal between the tape and the cable entrance port. The fiber optic adapter spool therefore restrains the optical fiber cable sheath within the splice closure while providing a seal between the cable and the end plate.
