Under the background of replacement of copper cables with optical fiber, it is beneficial for op-erators to fully make use of the existing copper cables for ultra-broadband access, with low construction cost and smooth evolution. This paper describes the princi-ple of Vectoring and the performance improvement to VDSL2, as well as G.fast and trials. The evolution of VDSL2 and G.fast are also discussed.
