New world record for data transfer: 3250 GB / second


Researchers at the Institute of Technology in Karlsruhe, Germany, broke the world record for data transfer. They managed to send the equivalent of nearly 700 DVDs in one second using a laser. In this experiment, the team of Professor Jurg Leuthold data encoded on a laser they have installed on a line of 50 kilometers. At the other end, they were able to retrieve data that had not undergone degradation. This method was used to measure the speed of data flow: 26 terabits per second, or 3250 GB per second.

To do this, Professor Jurg Leuthold said to have used a new form of coding: the Orthogonal Frequency Division Multiplexing (OFDM). This technology uses digital signals associated with frequencies. Jurg Leuthold added that with such a process, "one can transmit up to 400 million telephone conversations simultaneously.”What operators can only dream?
