Submission + - Copper wire can now handle 825Mbps data speeds (geek.com)
An anonymous reader writes: Network providers face a never-ending battle to keep up with demand from users for bandwidth while at the same time increasing the speed of their overall networks. One of the major limiting factors is that many networks still rely on copper wire rather than the superior fiber optic cabling. The networks therefore have to choose when to make the very expensive upgrade to fiber optic, and where those upgrades should happen first.
Thanks to some new technological breakthroughs, however, copper wire may be making a comeback. Current download speeds offered to end users range from 2Mbps-50Mbps, but we are all looking towards 100Mbps as the next milestone. While you may think fiber optic would be required for that, Nokia Siemens Networks has managed to employ phantom circuits to boost data-carrying capacity over copper wire to as much as 825Mbps over short distances of around 400 meters.
While the tech that achieved such high speeds may be a few years away, Ikanos has unveiled its NodeScale Vectoring technology allowing a minimum of 100Mbps data speeds over the same wires. It works by eliminating crosstalk on existing cabling allowing for much higher performance.
