Nokia and Australia’s NBN have completed an XG-Fast trial that achieved throughput speeds of 8 Gbps in lab conditions. XG-Fast, a Nokia Bell Labs-developed extension of Nokia's G.fast technology, is designed to enable operators to generate fiber-like speeds of more than 10Gbps over short distances using existing copper infrastructure. With a significant proportion of NBN's nationwide broadband network rollout being completed using existing copper networks, XG-Fast is being tested as a potential asset for future upgrades.
The XG-Fast trial conducted in NBN's North Sydney-based lab facilities generated peak aggregate data throughput speeds of more than 8 Gbps over a 30-meter twisted-pair copper cable typically deployed in field. A 5Gbps peak aggregate speed was achieved over 70 meters of twisted-pair copper cable.
