The research arm of Alcatel-Lucent has successfully showcased the delivery of super-fast broadband services through copper line networks.
Bell Labs achieved broadband speeds of 300Mb at distances of up to 400m through the use of DSL Phantom Mode, which uses two lines to reach the high rate.
It is thought that the solution could play a key role in boosting speeds across the UK, where a high number of broadband services run across copper-based networks.
Kamalini Ganguly, Analyst at Ovum, said DSL Phantom Mode could add "a whole new dimension" to the broadband debate.
"The fact that existing copper loops can facilitate 300Mb at 400m reshapes the whole next-generation broadband competitive environment - and will open up a wide range of new business opportunities for 'traditional' DSL players," she added.
BT recently confirmed it is upgrading 150 exchanges across the UK as part of work to expand coverage of its Wholesale Broadband Connect service.
