This article is a product guide for all dielectric self-supporting (ADSS) optical cables, which systematically introduces the all dielectric non-metallic structure, AN/AT voltage classification, span engineering design specifications, performance comparison with other overhead optical cables. 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. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission. Technical Guide for ADSS Single Sheath & Double Sheath Aerial Fiber Optic Cables ADSS (All-Dielectric Self-Supporting) cable is a type of Aerial fiber optic cable that supports its own weight without any metal in the construction. However, choosing the right ADSS cable can be overwhelming due to the variety of types and specifications available. It requires no messenger wire, withstands high electric fields up to 220 kV, and supports spans from 50 m to over 1,500 m — making it.
