Bury cables from 12-36 inches (or 30-90 cm) deep. 8 million km in scope by 2025 (per TeleGeography), burying these cords of light comes with the benefits of avoiding cable damage, decreasing downtime, and extending their operational lifetime. But how deep is fiber optic cable buried?It is often necessary to locate buried optical fiber cable to prevent dig-ups during construction, to access fibers for termination, to effect repairs, or for other reasons. This guide provides a comprehensive overview of industry. The short answer, based on general industry standards and the National Electrical Code (NEC), is that fiber optic cable is typically buried between 24 inches (60 cm) and 30 inches (76 cm) deep. However, simply hitting this depth isn't enough to guarantee your network survives.
