Huawei has conducted its G.fast over copper trial with a leading European telecom operator and unveiled a prototype capable of broadband speeds of 1 Gbps over coaxial cables. G.fast over Coax multi-user access technology is compatible with cable TV signals on existing coaxial networks, which serve as an access medium for home networks. By flexibly allocating unoccupied frequency bands (1 GHz maximally) for G.fast access, the technology provides a 1 Gbps downstream shared bandwidth to serve up to 32 users over coaxial cables. G.fast is mainly applied to short-distance twisted pairs to deliver Gigabit access. Huawei will incorporate the G.fast technology into its Fiber to the Door (FTTD) system, which takes fiber to the door and then delivers ultrafast broadband access via existing access media (copper lines or coaxial cables).
