Foreword: VDSL2 Point to Point Solution
VDSL2 (Very-High-Bit-Rate Digital Subscriber Line 2, ITU-T G.993.2 Standard) is an access
technology that exploits the existing infrastructure of copper wires that were originally deployed for
POTS services. It can be deployed from central offices, from fibre-fed cabinets located near the
customer premises, or within buildings.
ITU-T G.993.2 VDSL2 is the newest and most advanced standard of DSL broadband wireline
communications. Designed to support the wide deployment of Triple Play services such as voice,
video, data, high definition television (HDTV) and interactive gaming, VDSL2 enables operators
and carriers to gradually, flexibly, and cost efficiently upgrade existing xDSL-infrastructure.
ITU-T G.993.2 (VDSL2) is an enhancement to G.993.1 VDSL that permits the transmission of
asymmetric and symmetric(Full-Duplex) aggregate data rates up to 200 Mbit/s on twisted pairs
using a bandwidth up to 30 MHz.
VDSL2 deteriorates quickly from a theoretical maximum of 200 Mbit/s (Full-Duplex) at “source” to
100 Mbit/s at 0.3 km (symmetric) and 50 Mbps at 1 km, but degrades at a much slower rate from
there and still outperforms VDSL. Starting from 1.6 km its performance is equal to ADSL2+.
