Very high speed digital subscriber line 2
Encyclopedia
Very-high-speed digital subscriber line 2 (VDSL2) is an access technology that exploits the existing infrastructure of copper wires that were originally deployed for traditional telephone service
. It can be deployed from central offices, from fiber-optic
connected cabinets
located near the customer premises, or within buildings. It was defined in standard ITU-T G.993.2 finalized in 2005.
(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 was intended to enable operators and carriers to gradually, flexibly, and cost-efficiently upgrade existing xDSL infrastructure.
The protocol was standardized in the International Telecommunication Union
telecommunications sector (ITU-T
) as Recommendation G.993.2. It was announced as finalized on 27 May 2005, and first published on 17 February 2006. Several corrections and amendments were published in 2007 through 2011.
VDSL2 is an enhancement to very-high-bitrate digital subscriber line (VDSL), Recommendation G.993.1. It permits the transmission of asymmetric and symmetric aggregate data rates up to 200 Mbit/s downstream and upstream
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 (1,640.4 ft) and 50 Mbit/s at 1 km (3,280.8 ft), but degrades at a much slower rate from there, and still outperforms VDSL. Starting from 1.6 km (0.994196378639691 mi) 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 4–5 km (2.5–3 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 loop
s or MTU/MDUs only, but can also be used for medium range applications.
