At these speeds, network operators can significantly optimize existing copper infrastructure to deliver high-bandwidth services for years to come.

Nokia Siemens Networks uses circuits that involve creating a virtual channel—or 'phantom'—to complement the two physical wires that are the standard configuration for copper transmission lines. This approach, known as "Phantom DSL," will also be showcased at the Broadband World Forum 2010 in Paris, from October 26 to 28.

"The current FTTH fiber optic deployment remains expensive, even though it is capable of delivering very high speeds and is a definitive solution for long-term bandwidth requirements," said Eduard Scheiterer, head of the broadband access business line at Nokia Siemens Networks. "However, the innovative use of technologies such as phantom circuits helps operators provide efficient last-link connectivity over existing copper cables."

Phantom ADSL promises a bandwidth increase of more than 50-75% on existing bonded copper lines. This extends the lifespan of copper networks, delaying the need for fiber optic deployment and protecting existing investments made by operators. 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 high-bandwidth services.

Nokia Siemens Networks' Phantom DSL will become an integral part of the 562x/3x hiX DSLAM* products
