just ask Verizon. Regardless of how badly we all want a fiber optic cable ran directly into our closet, it's probably in our best interest if companies like Nokia Siemens Networks continue to improve existing services. Since we're on the topic, it's probably prudent to point out a new discovery surrounding existing copper wires -- one that involves data transmissions at up to 825Mbps. As the story goes, NSN is testing new technology (let's call it Phantom DSL) that could dramatically increase capacity of conventional copper wires, with the aforesaid data point coming on a trial transfer across 400 meters of wire; when stretched to 500 meters, it still held steady at 750Mbps. We're told that Phantom DSL promises a bandwidth increase of 50 to 75 percent over existing bonded copper lines, but mum's the word on when ISPs will actually have access. Yesterday, please?
Nokia Siemens Networks achieves world record copper DSL speeds
Paris, France – 25 October 2010
"Phantom DSL" reaches 825 megabits per second over 400 meters of copper lines
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.
