摘　　要：主要介绍了VDSL2矢量化、G.inp等铜缆接入技术的最新进展,结合实验室和现网测试结果,系统评估了VDSL2矢量化和G.inp的功能、性能和互通性,分析了技术发展趋势。结合电信运营商线路、设备、维护的实际情况,探讨了FTTx+VDSL2矢量化的部署模式及设备要求。VDSL2 vectoring and G.inp technologies and their progress were investigated. Based on the results of laboratory and field testing, VDSL2 vectoring and G.inp＇s functionalities, performance and interoperability were evaluated in detail. Combined with the status of telecom operators＇ networks construction and maintenance, VDSL2 vectoring and G.inp＇s deployment mode and equipment requirements in FTTx ＋VDSL2 scenario were proposed. Finally, development trend of VDSL2 vectoring and G.inp technologies and their application were given.
