Each installation will be influenced by local conditions. AFL-ADSS® (All-Dielectric Self-Supporting) cable is ideal for installation in distribution as well as transmission environments. 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. What is ADSS Fiber Optic Cable? ADSS fiber optic cable is a.
