ALU Achieves 10G over Copper Phone Lines at 30m

Bell Labs, the research arm of Alcatel-Lucent, demonstrated the ability to carry 10Gbps over traditional copper telephone lines over a distance of 30 meters.  Bell Labs also announced a prototype technology that can achieve 1Gbps symmetrical over existing copper access networks.


The Bell Labs tests used a prototype technology called XG-FAST, which is an extension of the G.fast standard being finalized by the ITU. When it becomes commercially available in 2015, G.fast will use a frequency range for data transmission of 106 MHz, giving broadband speeds up to 500 Mbps over a distance of 100 meters.

Bell Labs said XG-FAST uses an increased frequency range up to 500 MHz to achieve higher speeds but over shorter distances. Bell Labs achieved 1 Gbps symmetrical over 70 meters on a single copper pair. 10 Gbps was achieved over a distance of 30 meters by using two pairs of lines (bonding). Both tests used standard copper cable provided by a European operator.

Marcus Weldon, President of Bell Labs: “Our constant aim is to push the limits of what is possible to ‘invent the future’, with breakthroughs that are 10 times better than are possible today. Our demonstration of 10 Gbps over copper is a prime example: by pushing broadband technology to its limits, operators can determine how they could deliver gigabit services over their existing networks, ensuring the availability of ultra-broadband access as widely and as economically as possible.”
