  • Patent number: 5384880
    Abstract: The optical fiber cable has a plurality of centrally located optical fiber ribbons. Carrying the optical fiber ribbons is a gel-filled plastic buffer tube. An adhesive layer is applied along the outside of the buffer tube and yarns extend in a contra-helical pattern over the adhesive. The yarns are impregnated with a gel for lubricating the contact points between the yarns and a longitudinally applied mylar tape layer. The mylar tape layer is coated with a thin layer of sealant which permits application of final polyethylene outer jacket provided for additional cable protection. Embedded within the outer jacket is a pair of diametrically opposed, longitudinally extending strength members.
