Fiber optic cables can be installed either underground or aerially on poles. Underground installation involves burying the cables in trenches or conduits, typically 1–1.2 meters (3–4 feet) deep, to protect them from accidental damage, environmental hazards, and interference . In contrast, aerial installation is cheaper and faster, especially in rural areas where poles are available, but the cables are more exposed to storms, accidents, and other disruptions .
While underground installation is generally preferred for urban and high-traffic areas due to its durability and protection, fiber optic cables do not have to be laid underground. Aerial deployment remains a viable option in rural or cost-sensitive scenarios, though it carries higher exposure to environmental risks . The choice depends on factors such as location, budget, regulatory requirements, and long-term maintenance considerations.
