Bell Labs able to transmit 10Gbps broadband speed through copper-based telephone wires

The Bell Labs were able to bring a new threshold in broadband speed for copper-based telephone wires as they were able to push 10Gbps of internet speed. Alcatel-Lucent plans to new a DSL standard called XG-Fast.

The Labs were able to achieve this by using higher frequency of 500MHz. As an example, AT&T uses 106MHz frequency range for a 1Gbps threshold. However, it should be noted that transmitting higher frequencies via copper would require a lot of power, and therefore has a limitation of 10Gbps speed to up to 30 meters. The main advantage however is that unlike fiber, companies can use the existing copper-telephone wiring infrastructure to allow high speed internet connections.

Alcatel-Lucent said,“Bell Labs achieved 1Gbps symmetrical over 70 meters on a single copper pair. 10Gbps was achieved over a distance of 30 meters by using two pairs of lines (a technique known as ‘bonding’). Both tests used standard copper cable provided by a European operator.”

It was not said if these speeds will be implemented for the consumer or for commercial use.
