Yes it is 825Mbps over copper, even thought it was for a mere distance of 400 M (about 1312 feet) still it would be good news for the telephony carriers. At least they will be to over come the limits listed by cable companies like Comcast. During the same test Nokia, achieved 750 Mbps over a distance of 500 Meters (about 1650 feet), which is about how far away I am from the AT&T DSLAM switch.
There are few other players playing with the Phantom DSL, Bell Labs and Assia Inc, and bay area startup planing to take DSL to Gigabit speeds.
Nokia Siemens Press Release;
Nokia Siemens Networks has successfully tested a technology that could drastically increase the data carrying capacity of standard copper wires. The company achieved data transmission speeds of 825 megabits per second (Mbps) over 400 meters of bonded copper lines and 750 Mbps over 500 meters. At these speeds, network operators could optimize existing, widely deployed copper infrastructure to provide bandwidth-intensive services for years to come.
Nokia Siemens Networks used circuits that involve the creation of a virtual - or ’phantom’ - channel to supplement the two physical wires that are the standard configuration for copper transmission lines. The approach, known as Phantom DSL is also being showcased during Broadband World Forum 2010 in Paris,
October 26 - 28.
“Laying down new optical fiber to the home remains costly, though it is capable of delivering very high speeds and is a definite solution for long-term bandwidth requirements,” said Eduard Scheiterer, head of broadband access business line, Nokia Siemens Networks. “However, the innovative use of technologies such as phantom circuits helps operators provide an efficient last mile connectivity with existing copper wires.”
Phantom DSL promises a bandwidth increase of 50-75% over existing bonded copper lines. This prolongs the life of copper networks, delaying the need for fiber rollout and protecting operator’s existing capital investments. The promised high speeds will enable a whole new range of end-user services and open up new revenue opportunities for operators. The technology could be used to test initial demand for very high bandwidth services.
Nokia Siemens Networks’ Phantom DSL will become an integral part of the company’s DSLAM* products hiX 562x/3x.
