Very High Speed Digital Subscriber Line 2
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 as a way of delivering very high speed internet access. The main high-speed link (e.g. a fibre optic connection) terminates at a hub near the customers' location. The existing copper wire infrastructure is then used to carry the high speed connection for the short remaining distance to the customers. It can be deployed from central offices, from fiber-optic connected cabinets located near the customer premises, or within buildings. It has been defined in standard ITU-T G.993.2 finalized in 2005.

“Brutes are deprived of the high advantages which we have; but they have some which we have not. They have not our hopes, but they are without our fears; they are subject like us to death, but without knowing it; even most of them are more attentive than we to self-preservation, and do not make so bad a use of their passions.”

“The terror of the atom age is not the violence of the new power but the speed of man’s adjustment to it—the speed of his acceptance.”
—E.B. (Elwyn Brooks)
“The English never draw a line without blurring it.”
—Winston Churchill (1874–1965)
