What is VDSL

Refers to very high speed digital subscriber lines. It is the latest development in DSL, which enables high speed Internet access of up to symmetrical 100 Mbps (both up and downstream) and is specified to support applications such as multichannel high definition TV (HDTV), video on demand, videoconferencing, and VoIP, all using the existing ubiquitous copper telephone line infrastructure.

Very high Speed Digital Subscriber Line.

VDSL (very high speed digital subscriber line) download speeds are in the 13-55 Mbps range, over short distances, usually between 300 and 1500 meters, using twisted pair copper wire. The shorter is the distance, the faster the connection rate. VDSL2 (ITU-T G.993.2) allows speeds up to 100Mbps each way, but depends crucially on the length and quality of the copper loop. For loops longer than approximately 1.6Km it no longer provides a faster bit rate than ADSL2+.
