There are splice closures designed to be buried, mounted on walls, hung from cables or poles. Some are small pedestals themselves. Each type has a particular application and probably every application has a special closure. Compared to aerial routes, buried fibers are better protected against wind, lightning, ice, falling trees, vehicle impact and vandalism. They also remove visual clutter from urban skylines. For project owners and OSP designers, the key decision is not only whether to bury fiber, but how to choose. Depending on site conditions, underground fiber installation typically uses either conduit pulling or direct burial fiber optic cable. Best for urban or high-traffic areas, conduit pulling offers extra protection and easier future upgrades.
