Does the ADSS fiber optic cable contain metal
The ADSS fiber optic cable is fully dielectric, meaning it does not contain any metal materials, which makes it highly resistant to electromagnetic interference and safe to install near high-voltage power lines. Its structure and working principle allow it to transmit data efficiently over long. All-dielectric self-supporting (ADSS) cable is a type of optical fiber cable that is strong enough to support itself between structures without using conductive metal elements. At the same time, its installation and maintenance costs are also low, saving users a lot of costs. It does not need a messenger wire or any metallic support. "All-dielectric" means it has no metal parts.
