State-backed incumbent Swisscom has confirmed that it is conducting laboratory trials of Multiline next generation G.fast (NG.fast) technology in collaboration with Chinese vendor Huawei. According to the telco, the NG.fast upgrade is capable of providing 5Gbps speeds through a mixture of fibre optics and short copper cables. In a statement Swisscom explained that it has been testing the technology with vectoring on two lines since August, and has achieved throughput of between 1Gbps and 5Gbps under optimal conditions. Swisscom notes that due to the very high frequency of 500MHz, the technology requires that the copper element of the network is no more than 100m in length, making the platform particularly well-suited to Swisscom’s fibre-to-the-building (FTTB) network architecture. The telco went on to add that its G.fast service is now an important part of its technology portfolio, providing download speeds of up to 500Mbps to around 70,000 homes and businesses.
