Very-high-bit-rate 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.
