  • How much does it cost to move a telecommunications fiber optic cable to a pole

    How much does it cost to move a telecommunications fiber optic cable to a pole

    Installing or “overlashing” aerial fiber optic cable typically costs $8 to $12 per linear foot. When considering the cost per mile, this translates to approximately $40,000 to $60,000 per mile. Total Project Costs: For commercial installations, expect costs ranging from $5,000 to $20,000 per mile for underground projects and from $40,000 to $60,000 per. Home and business fiber optics projects typically range from a few hundred to several thousand dollars, depending on run length, fiber type, and labor needs. The main cost drivers are materials, installation time, and environmental factors that affect trenching, conduit, and terminations. The share of deployment costs attributable to labor costs range from 60 – 80%.
