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. While fiber optic cables are typically stronger than copper cables, it is still important that the cable maximum pulling tension not be exceeded during any phase of cable. Fiber optic cables are typically buried between 12 and 36 inches (30–90 cm), depending on installation environment, soil conditions, and load requirements. In high-load areas such as roads or backbone routes, burial depth can reach 48 inches (120 cm) or more. For broader context on underground.
