VDSL2 Service Deployment with Bonding: Longer Reach and Higher Rate Triple-Play Access

Overview: A major challenge facing telephone company operators in deployment of broadband access services is the issue of reaching all customers in the serving area with good signal quality suitable for triple-play service—voice, video, and data. The available bit rate on a twisted-pair cable is roughly inversely proportional to the length of the subscriber line. For triple-play services, VDSL2 is the leading access technology, since it operates with bandwidths of at least 8 MHz to enable downstream bit rates greater than 25 Mbps and upstream rates greater than 1 Mbps.
