3.1 Evolution of Residential DSL to G.fast
As DSL technology continues to improve, the copper wire length from a broadband provider's distribution point to the customer
premises has decreased, providing even greater speeds to customers.
ADSL relied solely on existing copper telephone wire infrastructure, connecting from the Digital Subscriber Line Access Multiplexer
(DSLAM) at the provider's central office to reach customer premises. With VDSL, fiber from the CO is deployed to a DSLAM at an
optical node (FTTN) closer to the customer premises, further shortening the length of copper cabling. VDSL2 and G.fast are capable
of closing the distance from a distribution point (FTTdp) to a few hundred meters of the end subscriber. G.fast supports speeds of
150 Mbps to 1 Gbps depending on the distance from the distribution point.
