CenturyLink offers the following types of broadband connections in select areas of the U.S.: ADSL, VDSL and Fiber. Thanks to its legacy network, the VDSL and ADSL networks are much more widely available.  ADSL (Asymmetric Digital Subscriber Line) is the traditional network that uses copper telephone wires for transmitting digital information such as data, audio and video, at a high bandwidth. VDSL (Very high bit rate digital subscriber line) is a newer technology that uses the same copper phone line, but delivers a faster connection speed. Fiber internet is the latest technology and delivers the best experience, but since the technology is new, the networks are still being laid out. Hence, you may not be able to access it in many places.
