VDSL2 Standard Finalised

Latest network specification spanks the butt of ADSL2+.

This one nearly sneaked past us. It seems the International Telecommunication Union’s conference held in Geneva this year snuck out a tasty piece of news just as it was closing up shop last week. VDSL2 has been ratified.


Now it is understandable if you don’t have the foggiest idea what this is, so here’s a recap. VDSL2 is the Holy Grail. It stands for “Very-high-bit-rate Digital Subscriber Line 2” and can deliver speeds of up to 100Mbps both up and downstream. That’s a ten-fold increase over the maximum speeds of a standard ADSL connection.

Naturally, VDSL2’s uses fair exceed that of blazing Internet access. It is the standard that operators are hoping will allow them to compete with cable and satellite providers by letting them offer services such as high definition TV (HDTV), video-on-demand, video conferencing, and highly advanced VoIP installations all over a standard copper telephone cable. The icing on the cake is that VDSL2 is interoperable with existing DSL equipment and it will work on both legacy ATM networks and next generation IP-based networks.

Like the wireless USB (WUSB) standard which was eventually finalised last week, VDSL2 has been argued about for ages, but now all systems are go. Expect VDSL2 trial announcements from telcos before the end of the year. Now we’re cooking!
