The evaluation of next-generation copper-wire technology

The FTTx+VDSL2 access network architecture is one of the best choices for the broadband access network, and migrating to the FTTH access network for carriers. However, it may be difficult to build the fiber into/in the house for some situation, such like the ful-filled line pipe and the decoration issues. The carriers have to introduce next-generation copper-wire technologies for higher rate to form a hybrid access network in the FTTH bottleneck areas. In this paper, we had studied the various technologies that could provide high speed access network and enlarge the coverage of the broadband service, including G.fast, Vplus and XG.fast. Furthermore, we also proposed the test technologies and results to verify the G.fast technology.
