What is Fiber-To-The-Home?


Fiber-To-The-Home (FTTH) is the latest technology in the broadband industry. It utilizes glass fibers, which conduct light, to transfer data. Duncan Cable has been utilizing fiber in our network since 1999, however, we have always been restricted by the traditional copper coaxial wire we use to distribute our internet service to our valued customers. FTTH brings that fiber directly to you, allowing us to offer much faster speeds, on a network that is more reliable, at the literal speed of light. If you would like more information about FTTH please read the FAQ linked below.
