The horizontal directional drilling (HDD) industry is at the forefront of the ongoing fiber optic revolution in the United States. As communities, businesses, and governments race to expand high-speed internet access, HDD has become the preferred technology for installing fiber optic cables with. While traditional trenching has been used for decades, Horizontal Directional Drilling (HDD)—also called directional drilling—is now the preferred solution for many fiber optic projects. In this guide, we'll explain why choosing directional drilling for fiber optic projects is the smart move, its. Look to Vermeer for highly productive equipment for installing high-speed fiber networks. HDD installation is a trenchless technique used to place underground fiber optic cables with minimal surface disruption.
