OCTOBER 25, 2010 -- Phantom DSL has struck again. Nokia Siemens Networks says it has used the technology to transmit data at 825 Mbps over 400 m of bonded copper lines and 750 Mbps over 500 m.
Back in April, Alcatel-Lucent Bell Labs announced it had achieved 300 Mbps over 400 m using what it called “Phantom Mode.”
Regardless of what you call it, the technology involves creation of a virtual -- or “phantom” -- channel to supplement the two physical wires that are the standard configuration for copper transmission lines.
Phantom DSL promises a bandwidth increase of 50-75% over existing bonded copper lines, Nokia Siemens Networks says. Such capabilities could prolong the life of copper networks and delay a wholesale switch to fiber to the home (FTTH).
Nokia Siemens Networks says its implementation of Phantom DSL will become an integral part of the company’s hiX 562x/3x DSLAM products.
