Direct buried optical cable is a way of laying communication optical cables. 101 describes characteristics, construction and test methods of optical fibre cables for buried application. 0, was redesignated as ITU-T L. It is required to have the performance of resisting external mechanical damage and preventing soil. Installing fiber underground is one of the most durable ways to protect a network's backbone — when it's done right. 2 meters (3-4 feet) deep to reduce the likelihood of accidentally being dug up. When connecting individual buildings, establishing campus networks, or deploying long-distance telecommunications lines, this cable can be buried directly into the. Underground fiber optic deployment has become the preferred option for modern broadband, 5G backhaul, FTTH, smart city networks and critical infrastructure. Compared to aerial routes, buried fibers are better protected against wind, lightning, ice, falling trees, vehicle impact and vandalism.
