Researchers make breakthrough advance towards potentially super-fast Internet A team of researchers from the University of California, San Diego, has surpassed the limits of transmitting fibre optic signals; thereby making a substantial breakthrough which can result in super-fast and cheap Internet.Highlighting the feat achieved by the researchers, a paper published in the university's Science journal on June 26 has revealed that the researchers managed to break the barriers in the way of increasing the maximum power, and hence the distance, for the transmission of optical signals through optical fibres.According to the details shared in the paper, researchers were able to transmit the fibre optic signals 12,000 kilometres - that is, nearly 20 times farther than the earlier maximum limit - without any significant degrading of signals.The breakthrough reported by the researchers implies that, theoretically at least, the rate of data transmission through optical fibres can be increased without distorting the information which travels through the fibre optic cable. The breakthrough advancement depends on wideband "frequency combs" which have been developed by researchers. Noting that the new findings effectively eliminate the requirement of electronic regenerators which are placed occasionally along the fibre link, the researchers said that the wideband "frequency combs" ensures that signal distortions in information travelling through fibre optic cables are predictable and, hence, reversible at the receiving end of the fibre.
