Underground cables are pulled in conduit that is buried underground, usually 1-1. In extreme cold climates, cables may need to be buried at greater depths where there temperatures are colder and frost penetrates to. 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. Factors like the. The NEC Article 830. 47 specifies 18 inches as the minimum depth for direct burial of network-powered broadband communication systems, which includes fiber optic cables. The NESC provides more. Expect anywhere between three to ten feet (1-3 meters) of bury to withstand such natural scour, or to sink below wave agitation notably caused by tidal amplification, given anchoring usually takes place in shallow water at some interval with much resting below bedrock.
