ADSS (All-Dielectric Self-Supporting) — a standalone, nonconductive jacketed cable that carries its own weight between poles without a supporting steel strand. ADSS is used where electrical isolation is needed (near power lines) because it has no metallic messenger. The steel messenger acts as a structure that supports the weight of the fiber. Steel messenger strand consists. Deploying fiber above ground on poles or towers removes the need for underground digging and is particularly useful when the ground is uneven, rocky or both. Aerial optical cables are available in a variety of designs to suit every overhead application.
Common cable trays are made of galvanized,, aluminum, or glass-fiber reinforced plastic. The material for a given application is chosen based on where it will be used. Galvanized tray may be made of pre-galvanized steel sheet fabricated into tray, or may be hot-dip galvanized after fabrication. When galvanized tray is cut to length in the field, usually the cut surface will be painted with a zinc-rich compound to protect the metal from corrosion.
Please refer to the Installation – General Guidelines of the Optical Cable Corporation Installation Guide. Cable blocks should be suspended beneath the steel messenger and are used to temporarily support the cable beneath the steel messenger until it can be lashed. 316 is used to provide the best insurance against failure under the most severe atmospheric conditions including chlorides and sulfides 5% to length for Cable Bundles up to 1. diameter 20% to length for Cable Bundles. Corning Optical Communications self-supporting (figure-8) optical fiber cable greatly simplifies the task of placing fiber optic cable on an aerial plant. Fiber in a duct solutions have a major aesthetic.
