DOCSIS3.1 technology becomes more and more mature. The coaxial access has started the era when the download rate is 10G and the upload rate is 2G. To respond the demand of increased upload bandwidth in future, the full duplex technology will present the equal upload and download rates of 10G (even 25G). So far, Huawei has completed research on key technology of full duplex and prototype development, and made its contribution to continuous development of coaxial access.
