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 operators 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 companys DSLAM* products hiX 562x/3x.
