[Network] VDSL2

VDSL2 is attractive to carriers for a number of reasons, the most important being that it utilizes existing copper infrastructure.
With about 1.3 billion copper phone lines in place worldwide, VDSL2 presents carriers with an opportunity to expand revenue-generating services across those phone lines with only a modest investment, especially as compared with running fiber all the way to the customer premises.

VDSL2 is much cheaper(about $250) to deploy than fiber(about $1100 per home) which has caught the attention of carriers in Europe, Asia, and North America, whether or not they've announced fiber deployments. In many cases, carriers are utilizing VDSL2 in combination with fiber, developing triple-play infrastructure even faster than they originally intended. That infrastructure will carry the new services – including video on demand (VOD), high-definition TV (HDTV), and interactive gaming – that telcos hope will breathe new life into their revenue streams.


As telcos continue to feel the heat of competition from cable and satellite providers, one question will determine who wins this triple-play war: Will consumers have more confidence in a cable or satellite company delivering high-quality voice, or in the phone company delivering high-quality video? The challenge for telcos is to convince consumers that they can deliver video as well as they've been delivering voice and data. And VDSL2 may well be the technology that helps them meet that challenge head on.
