Cable installation standards cover direct burial, conduit pulling, lashed and ADSS aerial cables. Aerial Cable Installation 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. The choice of these two types depends on the installation location. If we want to install the fiber optic cable on a path that already has support and don't have to worry about the span of the fiber optic cable. Aerial fiber optic cable refers to a kind of fiber optic cable that is designed and used for outside plant (OSP) installation between poles by being lashed to a wire rope messenger strand with a small gauge wire. This article explains the common aerial cable types, the hardware you'll actually use on poles and span ends, and the safety practices. ons, and company safety practices and policies. Failure to do so can result in life-threat t truck or on a ladder so that it cannot fall. Materials and equipment should not unnec lled for in your company's safety proced s and, if necessary, lineman's rubber gloves.
