This article will compare fiber optic and copper cables in terms of performance, durability, security, cost, and typical uses. Understanding these differences will help you pick the best option to meet your network's specific needs. Most aerial fiber optic cables are installed by lashing to a steel messenger wire strung between poles, but there is a category of cables with special high-strength jacket designs called all-dielectric self-supporting (ADSS). Besides the use of special cables on transmission and distribution towers or poles, the installation of fiber optic cables for utilities may require the shutdown of electrical distribution for installation, although some installations are possible without shutdown. Making an informed cable choice is critical for any organization. W hen deploying a fiber optic network, one of the most critical decisions is whether to install fiber cables aerially (on utility poles) or underground (buried beneath the surface).
