VDSL2 (Very High Speed Digital Subscriber Line 2) is an access technology that exploits the existing infrastructure of
copper wires that were originally deployed for
POTS services. It can be deployed from central offices, from fibre-fed
cabinets located near the customer premises, or within buildings.
VDSL2 is the newest and most advanced standard of
DSL broadband wireline communications. Designed to support the wide deployment of
Triple Play services such as voice, video, data, high definition television (HDTV) and interactive gaming, VDSL2 enables operators and carriers to gradually, flexibly, and cost efficiently upgrade existing xDSL-infrastructure.
It has been standardized as
ITU G.993.2 in February, 2006.
ITU-T G.993.2 (VDSL2) is an enhancement to G.993.1 (
VDSL) that permits the transmission of asymmetric and symmetric (Full-Duplex) aggregate data rates up to 200 Mbit/s on twisted pairs using a bandwidth up to 30 MHz.
VDSL2 deteriorates quickly from a theoretical maximum of 250 Mbit/s at 'source' to
100 Mbit/s at 0.5 km (1640 ft) and
50 Mbit/s at 1 km (3280 ft), but degrades at a much slower rate from there, and still outperforms
VDSL. Starting from 1.6 km (1 mile) its performance is equal to
ADSL2+.
ADSL-like long reach performance is one of the key advantages of VDSL2. LR-VDSL2 enabled systems are capable of supporting speeds of around 1-4 Mbit/s (downstream) over distances of 4 to 5 km (2 ˝ to 3 miles), gradually increasing the bit rate up to symmetric 100 Mbit/s as loop-length shortens. This means that VDSL2-based systems, unlike VDSL1 systems, are not limited to short
local loops or MTU/MDUs only, but can also be used for medium range applications.
