Line bonding, noise cancellation solutions could enable high-speed broadband access, mobile backhaul over copper lines.
Ericsson on Monday announced it has successfully tested high-speed VDSL2 technology at speeds of over 500 megabits per second.
The Swedish equipment vendor achieved the high data transfer rates over twisted copper pairs using new line bonding and crosstalk cancellation technology, which it calls 'vectorised' VDSL2.
Six lines were bonded in order to reach speeds above 500 Mbps at 500 metres. Crosstalk cancellation technology reduces the effects of noise from other copper pairs in the same cable bundle, enabling Ericsson to extend the capacity and reach of the signal to more people.
The company said standards for VDSL2 line bonding are already available, while standardisation of vectoring is expected by the end of 2009.
VDSL2 enables operators to offer access to the latest high-speed broadband services using their existing copper lines.
"With this technology, operators can enhance fibre access deployments with copper access in the last mile and thereby maximise the reuse of existing infrastructure," the vendor said in a statement.
"It also proves Ericsson's abilities to provide future mobile backhauling, which will enable quick and cost-effective introduction of Long Term Evolution (LTE) solutions," said Hakan Eriksson, CTO of Ericsson.
Ericsson said VDSL2 will allow a larger number of consumers to access demanding services including HDTV and video-on-demand (VoD) via their broadband connection.
Eriksson said the demonstration confirms Ericsson's "commitment to the continued research and development of DSL technology to improve operators' business with new access solutions." - source
