Huawei breaks DSL speed barrier with 700Mbps prototype

DSL cables might not really be the sexiest thing in networking anymore, but what they are is ubiquitous, so let's not begrudge Huawei its feat here. The Chinese telecoms facilitator has shown off a new prototype that can pump 700Mbps of data across a 400-meter expanse. This is done by bundling four twisted pairs of copper wire together and sprinkling in some fairy dust to make them communicate at 175Mbps each. The clever bit here is in how crosstalk and interference are minimized, and Huawei claims a 75 percent improvement in bandwidth as a result. An immediate opportunity for these new cables will be, ironically, with fiber rollouts, as they could serve as the last connection between fiber hubs and your home. Then again, with Google and Chattanooga already looking at 1Gbps lanes, maybe the day of the copper wire has already passed?Continue reading Huawei breaks DSL speed barrier with 700Mbps prototypeHuawei breaks DSL speed barrier with 700Mbps prototype originally appeared on Engadget on Fri, 24 Sep 2010 09:17:00 EDT.
