VDSL (very high bit-rate DSL) is an xDSL technology providing data transmission up to a theoretical limit of 52 Mbit/s downstream and 12 Mbit/s upstream over a single twisted pair of wires.

Currently, the standard VDSL uses up to 4 different frequency bands, two for upstream (from the client to the telco) and two for downstream. The standard modulation technique is either QAM (Quadrature amplitude modulation) or DMT (Discrete multitone modulation) which are not compatible, but have similar performance. The current mostly used technology is DMT (the same technology used in cable modems). Quadrature amplitude modulation (QAM) is a modulation scheme which conveys data by changing (modulating) the amplitude of two carrier waves. ... Orthogonal frequency division modulation (OFDM, also called orthogonal frequency division multiplexing) is a technique for the modulation of digital information onto an analog carrier electromagnetic (e. ...

The available bit rates ranges from about 26 Mbit/s symmetric for a loop of about 1500 m, up to 100 Mbit/s symmetric for a few hundred metres.

VDSL is capable of supporting high bandwidth applications such as HDTV. Qwest is currently prototyping the service and may offer a HDTV package as early as 1Q 05.

A new VDSL standard is now available, named VDSL2; no current rollouts are known. It has been suggested that this article or section be merged into VDSL. (Discuss) VDSL2 (Very-High-Bit-Rate Digital Subscriber Line 2, ITU-T G.993. ...
