Speed up about 10 times is not a dream，

Speed up about 10 times is not a dream-a fiber-optic cable, data transfer rates, cable data transfer rate-it news Speed up about 10 times is not a dream

Since the last century 70 's since the advent of cable, new technological innovations make an average of once every 4 years, its transmission speeds up to 10 times, but we seem to be experiencing a bottleneck in recent years.

Scientists around the world are struggling to cross the narrow bottleneck, at Swiss Federal Institute of technology in Lausanne the first to complete this task. Their papers published in the journal Nature on Communications revealed a cable data transfer rates up to 10 times.

All along, researchers understand that reduce ISI is a proper course, but too little distance will always produce signal interference, nobody will solve this problem. The Lausanne's team found that hid the Holy Grail of signal compression in frequency of the signal value.

By using the same frequency pulse signal, interference by scientists to avoid similar signals, access 99% data accuracy ideal impulse.

Camille, one of the study co-author Br Grands s said "in order to be able to mix them together, the more sharply than normal pulse pulse shape, you may want to think about each piece of the puzzle interface looks like. Of course, such signal interference will still exist, but they are not on our part that reads data. ”

Researchers say the technology is already quite mature, cost is less expensive, can be put into commercial popularity, they expect the cable industry will adopt this technique.

网速再提10倍不是梦

自从上世纪七十年代光缆问世以来，新技术革新使得平均每过4年其传输速度就会提升10倍，但近几年我们似乎遇到了瓶颈。

世界各地的科学家都在努力穿过这段狭小的瓶颈，位于洛桑的瑞士联邦理工学院率先完成了这项任务。他们发表在《Nature Communications》上的论文揭示了一种将光缆数据传输速率提高10倍的方法。

一直以来研究者们都明白缩小信号间距是一条正确的路线，但过小的距离总会产生信号干涉，没人能解决这个问题。这只洛桑的团队发现，这个信号压缩的圣杯藏在各信号的频率值当中。

通过用同一频率发射脉冲信号，科学家们得以避免相近信号的干涉，获得99%数据准确性的理想脉冲信号。

该论文合著者之一的Camille Brès表示“为了能把它们搭配在一起，这种脉冲的形状比普通脉冲更尖锐，你可以想想一下拼图的每一片相互衔接的样子。当然，这种信号仍会存在干涉，但它们都不在我们读取数据的部分。”

研究者们表示该技术已经相当成熟，造价也不昂贵，完全可以投入商业普及，他们期望光缆工业会采取此技术。
