At its core, ADSS (All-Dielectric Self-Supporting) cable is a specialized fiber optic cable whose purpose is to provide a reliable communication link in environments where traditional cables are unsuitable. The meaning behind the name "all-dielectric" signifies that the cable contains no conductive metal components, making it completely non-conductive. This is essential for preventing electric current induction and ensuring safety when the cable is installed near high-voltage power lines. The "self-supporting" aspect means the cable's internal structure is strong enough to bear its own weight over large distances, eliminating the need for a separate messenger wire.
