Akhir 04, 1432 H/March 09, 2011, SPA -- A fibre-optics connection in Berlin has set a new world data-speed record of 10.2 terabits per second, scientists said Wednesday, opening up the prospect of faster internet links. The per-second quantity of serial data, four times the old record, is equivalent to the contents of 240 completely full DVD disks, dpa reported. Testers pushed the data as flashes of light through a 29-kilometre coil of single-strand optical fibre at the Fraunhofer Heinrich Hertz Institute in the German capital. The Technical University of Denmark shared in the research. To beat the former record of 2.56 terabits per second, scientists increased the pulse rate of the light flashes and increased the amount of data encoded in each pulse to four bits. Current commercial systems crossing the world's oceans only transmit 1 bit per pulse. An announcement said the record would be presented at the Optical Fiber Communications 2011 conference Thursday in Los Angeles.
