What: VDSL2 (very high-speed digital subscriber line 2)
Why you should care: The second VDSL standard offers higher power output and more bandwidth than VDSL1, and can be used in somewhat longer-range deployments than its very short-range predecessor. It offers peak theoretical downstream bandwidth of around 100 Mb/s. Though real-world deployments would be lower, VDSL2 still improves the potential of DSL to compete against cable modems and it can be deployed along with other DSL flavors, such as ADSL2.
Who's using it: Broadband World Forum Europe in Berlin last week showcased some of the companies supporting VDSL2, including carriers such as Melgacom and Deutsche Telekom, and vendors such as Ericsson, Alcatel-Lucent, ECI Telecom, Zyxel, Wintegra, Broadcom and many others.
