VDSL - Very High Digital Subscriber Line

A variant of HDSL (High Digital Subscriber Line) which provides a service at data rates greater than 10Mbps. With this increased data rate, there is a significant decrease in the radius which such a system can operate. For this reason a VHDSL system would be implemented with fibre optics transporting the data to a remote sight near the subscribers, and use VHDSL to bridge the last 30 metres or so to the subscriber.
