VDSL

September 12, 2007

VDSL, or Very high bit-rate Digital Subscriber Line, is a type of superfast broadband with download speeds of up to 50Mb. The second generation VDSL service can reach even faster speeds of 100Mb for upload and download. VDSL is transmitted via twisted copper wires in a phone line and can handle broadband and high-bandwidth services such as VoIP, and IPTV.

However it does suffer from attenuation over longer distances (attenuation is the loss of the broadband signal as it makes its way from your exchange to your home).
