Powerguide tracking-resistant fiber-optic cable suits aerial distribution, transmission networks and long-span point-to-point applications. Its jacket allows placement in electric fields of up to 25 kilovolts without damaging the outer sheath material. This all-dielectric self-supporting fiber-optic cable accommodates spans to 3000 feet, depending on loading conditions, fiber counts and sag restrictions. The cable can be designed per customer application to optimize performance. Its one-step installation uses common attachment hardware, minimizing installation costs. Optical transmission is immune to electromagnetic interference, eliminating the need for expensive shielding and grounding precautions. The optical fibers are protected within oversized, gel-filled buffer tubes. Both buffer tubes and fibers are color-coded for identification. The cable incorporates a one-layer aramid-yarn-reinforced, double polyethylene jacket.
