Network equipment vendor giant Ericsson claims to have conducted the telecom industry's first live demonstration of vectorized VDSL2, reaching a rate of more than 500Mbps, or half a gigabit per second. The company told Network World that commercial vectorized VDSL2 products could enter the market mix by the end of this year, around the same time that an industry standard for the technology could be ready.
Vectorized VDSL2 uses multiple copper lines to increase DSL bandwidth, while canceling the noise that would normally occur under such conditions. It would be most useful in multi-dwelling units or other areas where there is both a proliferation of copper lines and a short reach for the DSL line. The resulting bandwidth, however, could support IPTV and many other video applications, in addition to broadband Internet access and telephone service.
VDSL2 (non-vectorized) already has proved itself as a broadband option capable of supporting TV services in the right deployment scenario, and raising the bandwidth ceiling could only elevate its promise. The technology has won some increasing support within the last year--notably from Nokia Siemens Networks--even as Verizon Communications found new ways to push fiber into MDU buildings.
