VDSL2 stands for Very High Bit Rate Digital Subscriber Line 2nd Generation. This is an enhancement to the original VDSL (Very High Bit Rate Digital Subscriber Line) but runs on a different frequency (30 MHz) over 7 different bands that produce extremely high bandwidth capabilities.
VDSL2 is designed to deliver high-speed Internet access for triple services such as IPTV/HDTV, video-conferencing, remote lecturing, telemedicine and video-on-demand services. It is compliant to ITI-T G.993.2 standard which was announced on 27 May 2005, and first published on 17 February 2006. Several corrections and amendments were published from 2007 to 2011. VDSL2 features the transmission of asymmetric and symmetric aggregated data rates up to 300Mbit/s downstream and upstream over twisted pairs using a frequency up to 35MHz.
VDSL2 has replaced ADSL as the most popular xDSL technology. Today, VDSL2 and its variants represent over 60 percent of total DSL annual shipments.
