Did you know PureEdge Technologies specializes in Fiber Optic Cabling, this is a technology that uses light as a digital information carrier. Fiber-optic cables are a direct replacement for coaxial cables and twisted-wire pairs (common cables used for voice and data). The glass-based transmission facilities occupy far less physical volume yet provide a tremendous amount of transmission capacity, which is a major advantage in crowded underground ducts. The fibers are immune to electrical interference, which is another advantage.
