Abstract "Fully Dry Optical Cables" The present invention relates to the development of fully dried double layer loose pipe optical cables that surrounds the area of optical communication; The cable includes a set of elements with a reinforced center, loose pipe double layer dielectric center element, moisture blocking bands (wtb), mechanical reinforcement wires and outer sheath. on the outside of the reinforced central element assembly are the moisture blocking bands (wtb), a double layer dielectric central element of loose tubes which is formed by an inner and outer layer of dry and braided loz tubes with sz shape and there is shape, three formats: inner layer with 06 loose tubes and outer layer with 12 looses tubes, inner layer with 07 looses tubes and outer layer with 13 looses tubes, inner layer with 09 looses tubes and outer layer with 15 looses tubes. each basic unit has 12 fiber optics, 1-2 moisture-free, non-jamming wires; Between the loose pipe layers and the dielectric central element with the double pipe loose layer the moisture blocking bands (wtb) are coated. the reinforcing wires are wound around the surface of the moisture blocking bands (wtb) that make up the dielectric central element with double layer looses. the reinforcement wires have ripcord and outer sheath. The shape of the optical cable is totally dry. With this invention, the maximum cable capacity may contain 288 cable-free, non-jelly optical fibers, maintaining the impermeability of the optical cable, reducing the weight and increasing the mechanical behavior of the cable and the efficiency of installing and performing the optical splices, and, In addition, protecting the environment. 1/1
