A1 Telekom Austria and Nokia have demonstrated transmission rates of over 11Gbps via the operator’s conventional copper cables in its fixed line network. The test involved an advance in existing G.fast technology known as XG-FAST, which uses the final stretch of the existing copper network to bring super-fast internet to homes and offices. It was conducted in Vienna using 30m copper cable and test equipment supplied by Nokia Bell Labs, the company’s research lab. ‘XG-FAST enables us to bring fibre-optic speed internet to our customers over our existing telephone copper wires,’ commented Sascha Zabransky, Telekom Austria Group’s Director of Technology and Future Services, adding: ‘We remain faithful to our long-term vision to bring fibre-optic lines to every home, however, until then, XG-FAST will serve as a smart bridging technology.’
A1 Telekom notes that G.fast and XG-FAST technologies are particularly suitable for fibre-to-the-building (FTTB) expansion in residential areas; under this model the firm installs high speed fibre-optic lines to a node in the cellar of the building or the boundary of the property, which then connects with the existing line.
