While you're busy pining away for Google Fiber, a group of researchers at the Technical University of Denmark have been busy putting it to shame. Trumping their last network milestone achieved back in 2009, the group has developed a fiber network that pushes more than 5TB of data per second through a single optical cable.
The network gives users speeds of 43Tbps, which works out to about 5.4TB per second. As the folks at Extreme Tech pointed out, such speeds would allow you to download a 1GB movie in 0.2 milliseconds -- or better said, in the blink of an eye. The university -- henceforth called DTU -- is notable for many reasons, not the least of which was being the first to exceed the single terabit milestone, something that took place back in 2009. Though hard at work, Karlsruhe Institute of Technology set the latest record back in 2011 at 26 terabits, something that has persisted until now. The speeds were achieved using a single-laser and single-fiber setup, with multi-core fiber being used to hit the faster speeds. While you won't be seeing these speeds in your home any time soon, it is an important milestone for ushering us closer. 翻译:
当你还在纠结该不该申请Google Fiber(谷歌光纤网络服务,70美元就可以享有1GBPS的网速,TMD,马来西亚为毛没有??)的时候,丹麦的科技大学(Technical University of Denmark)就已经研究开发出了让谷歌感到惭愧的网速。距离他们(丹麦科技大学)为光纤网速投下里程碑的时间已经有好几年了,最近的一次是2009年。这次这群精英成功地开发了一个可以由单单一条光纤电线就可以一秒传送超过5TB网速的网络。
这个网络能让玩家享受到43TBps的网速,换算过来也就是5.4TBps(TM惭愧没有??)。Extreme Tech的人说,一部1GB的电影可以在0.02微秒下载好,名副其实的一眨眼功夫。
丹麦的这所大学确实是拥有不少可造之材,他们在2009年可是头几个研究出超过1TBPS的一群人。尽管开发上有一定的难度,Karlsruhe Institute of Technology(科技学院)在2011就已经研究出了26TBPS的网速。
这个速度是由一条单雷射和单条光纤电线,再加上多核心光纤来达到。虽然往后十几年才会看到在家里会有这等网速(到时还会有更快的网速),但是这无疑是一个里程碑。

个人感想:一秒5TB的网速够我一次下载好几十部1080P的电影了,流口水中~~~~~~,但是应该再20年才能看到吧,希望到时TM能跟上时代的变迁,与时并进啊~~~~~~~
