VDSL2
Very high speed digital subscriber lines (VDSL) is a new standard that
allows extremely high speed internet access over existing copper cables.
The VDSL2 standard increases the spectrum allocation up to 30 MHz for
even higher performance than its predecessor VDSL1, and allows speeds
up to 100 Mbps symmetrical (both up and downstream). VDSL2 also calls
for support of applications such as multi-channel high definition TV
(HDTV), video on demand, video-conferencing, and VoIP using the existing
copper telephone line infrastructure. Along with that it also calls for ATM,
Ethernet, and IP compatibility, as well as multimode implementations to
permit interoperability with existing ADSL equipment.
VDSL2 gives carriers the flexibility to start rapidly deploying VDSL2
networks and offer new broadband services including triple-play services,
HDTV, VoD, high-speed data, VoIP, high-speed Internet access, video
conferencing, virtual private networks (VPNs), PBX Extension, and video
surveillance to compete with cable companies. VDSL2’s broader spectrum
combined with features like Trellis coding and multi-pair bonding allows
carriers to offer full triple-play services to a large portion of their customer
base.
