超宽带铜线接入技术Vectoring与G.fast

Vectoring and G.fast:the Ultra-broadband Access Technologies for Copper

目前,光进铜退在很多情况下依然是一个需要解决的问题和需要抓住的机遇:充分挖掘铜线接入潜能提供超宽带接入,对于电信运营商降低网络建设成本、平滑演进具有重要意义。阐述了Vectoring技术原理、VDSL2性能的提升,以及G.fast技术和现场实验,并对VDSL2和G.fast技术演进方案进行了讨论。

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.
