The GYFTYC8S optical cable is a figure-8 self-supporting outdoor communication cable specifically designed for aerial installation. It features a loose tube, stranded, filled core structure that integrates the fiber protection unit with a high-strength steel messenger wire in a distinctive figure-8 cross-section. This design allows the cable to be directly suspended between utility poles without requiring a separate support wire, significantly simplifying the installation process and greatly reducing the cost and time for deploying aerial lines.
