High speed Internet connectivity is made possible by the DSL standard known as VDSL (Very high bit rate Digital Subscriber Line). With download rates of up to 52 Mbps (6.5 gigabytes per second) and transfer speeds of up to 16 Mbps, it is an enhanced form of ADSL (asymmetric DSL) (2 megabytes per second).

VDSL can be installed over current telephone cabling and works over copper cables, just like earlier DSL specifications. This means that an ISP can offer customers VDSL Internet access as long as they have a phone and are situated within a certain range that the ISP specifies. A VDSL modem, which links to a computer or network on one end and a phone receptacle on the other, establishes the connection.

The increased bandwidth needs of HDTV, video streaming, and Telephony links were supported by the development of VDSL. VDSL has enough capacity to handle all of these links concurrently by offering downward transfer speeds of over 50 Gbps. VDSL is able to compete with cable Internet companies, who previously provided quicker Internet access speeds, thanks to their rapid data transmission rates.

Online service companies still frequently offer the 2004-approved ITU standard G.993.1, the first iteration of VDSL. VDSL2 (ITU standard G.993.2) is an upgraded variant that was released in 2006 and provides symmetrical download and transfer rates of 100 Mbps. Businesses and other groups that require high-speed links for numerous systems are frequently given VDSL2.
