AUSTRALIAN NBN PUSHES HOME COPPER BROADBAND TO 8GBPS
Australia’s National Broadband Network (NBN) wholesale operator has pushed the speed of broadband over traditional copper wires to 8Gbps in a trial in its Sydney labs with Bell Labs.
The company, which is charged with delivering last-mile broadband to Australian homes and businesses as a wholesale provider to retail operators, was working with Bell Labs, the Us-based research centre that is now owned by Nokia.
The technology “gives us the ability to deliver multi-gigabit speeds over copper lines – virtually on a par with what is currently available on fibre-to-the-premises – but at a lower cost and time to deploy,” said NBN’S chief technology officer, Dennis Steiger. The trials took place at NBN’S labs in North Sydney.
Nokia said the technology, which is called XG-FAST, could eventually deliver 2Gbps over 100m of copper from cabinet to customer.
The NBN trial delivered 8Gbps over a 30m twisted-pair copper cable typically deployed in field, and a peak aggregate speed of 5Gbps over 70m.
