An overview of VDSL2 vectoring

Vectored DSL as defined in ITU-T Recommendation G.993.5 supports line speeds of greater than 100 Mbps on loops up to 500 meters in length, enabling the most advanced application services to be carried over copper.

With appropriate placement of DSLAMs, use of management tools and techniques such as bonding of vectored lines and use of DQM techniques, vectored DSL becomes an important tool for network operator to provide broadband services such as IPTV to all their customers.

The emergence of vectored DSL provides the DSL based service provider with the tools that facilitate supporting the bandwidths required for higher valued premium services over their existing copper based networks and helps ensure that deployment of DSL increases as broadband services continue to evolve.
