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.
Explore 19 top manufacturers and suppliers of Polarization-Maintaining Fiber Optic Fibers in our comprehensive photonics buyers' guide.
