Nokia Siemens Networks (NSN) reports that they have successfully tested a technology that could drastically increase the data carrying capacity of standard copper wires.<\/p>\n
The company says that they achieved data transmission speeds of 825 megabits per second (Mbps) over 400 meters of bonded copper lines and 750 Mbps over 500 meters.<\/p>\n
At these speeds, network operators could optimize existing, widely deployed copper infrastructure to provide bandwidth-intensive services for years to come, NSN says.<\/p>\n
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. According to NSN the approach is known as Phantom DSL.<\/p>\n
“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.<\/p>\n
“However, the innovative use of technologies such as phantom circuits helps operators provide an efficient last mile connectivity with existing copper wires.”<\/p>\n
Phantom DSL promises a bandwidth increase of 50-75% over existing bonded copper lines. NSN says that this prolongs the life of copper networks, delaying the need for fiber rollout and protecting the operator’s existing capital investments.<\/p>\n
Nokia Siemens Networks says that Phantom DSL will become an integral part of the company’s DSLAM products hiX 562x\/3x.<\/p>\n
