ABSTRACT:
A long-distance transmission fiber optic cable system suitable for outdoor aerial installation includes a continuous length of non-metallic messenger cable with an aramid fiber, tension load bearing core and a predetermined tension load bearing strength and a polymer outer jacket adapted for outdoor exposure and a continuous length of fiber optic cable, longer than the continuous length of non-metallic messenger cable and including a plurality of fiber optic waveguides within an outer polymer jacket adapted for outdoor exposure and having a tension load bearing strength less than the predetermined tension load bearing strength, and preferably non-metallic, helically wound around the continuous length of the non-metallic cable so as to permit free axial movement. Continuous lengths of 40,000 feet or more of the preferred non-metallic messenger cable and fiber optic cables suitable for outdoor use have been made. The cable system may be hung with electric power transmission lines, and may be used to span gaps of more than one half mile.
