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.

Famous quotes containing the words high, speed and/or line:

    While yet a boy I sought for ghosts, and sped
    Through many a listening chamber, cave and ruin,
    And starlight wood, with fearful steps pursuing
    Hopes of high talk with the departed dead.
    Percy Bysshe Shelley (1792–1822)

    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)

    A line in long array, where they wind betwixt green islands;
    They take a serpentine course—their arms flash in the sun—hark to the musical clank;
    Walt Whitman (1819–1892)
