Price of overhead optical cable construction

The cost of constructing new overhead (aerial) optical fiber cables typically ranges from $5 to $14 per foot, or approximately $40,000 to $60,000 per mile, depending on labor, pole usage, and installation method.

Cost Breakdown

Materials and Cable: Aerial fiber optic cables vary in strand count, from 36 to over 1,700 fibers per cable, with higher strand counts increasing material costs but providing future network capacity. Installation Methods: Overlashing: Attaching new fiber to existing cables on poles costs about $8–$12 per linear foot, translating to $40,000–$60,000 per mile. New Pole Attachments: Using new poles or renting space on existing poles increases costs, with median aerial build costs around $4.

90/foot for owned poles and $7. 00/foot for rented poles. Labor Costs: Labor is a major component, accounting for 60–80% of total deployment costs.

Median labor costs for aerial installation are approximately $4/foot, with outsourced labor being higher.

Permitting and Make-

Ready Work: Obtaining permits and preparing poles for new attachments can add to costs and project timelines. Delays in approvals or increased attachment fees can significantly impact the total budget. Other Factors: Environmental conditions, terrain, and local regulations can influence costs.

Aerial installation is generally faster and less expensive than underground deployment, but it is more exposed to weather and physical damage.

Summary

For planning purposes, expect aerial fiber construction to cost roughly $40,000–$60,000 per mile, with variations depending on whether poles are owned or rented, labor rates, and installation complexity. Overlashing existing cables is a cost-effective method, while new pole installations or challenging terrain can increase expenses. Proper budgeting should also account for permitting, make-ready work, and potential delays.
