German scientists at the Karlsruhe Institute of Technology (KIT) have managed to achieve yet another world record successfully encoding data at a rate of 26 terabits per second using but a single laser beam, helping transmit such data over a distance of 50km, followed by a successful decoding session. To put things into their proper perspective, this is the largest data volume that has been transported to date on a laser beam. The process which was developed by KIT basically lets one transmit the contents of 700 DVDs in – get your calculators out – just one second.
In this experiment, the KIT scientists from Professor Jurg Leuthold’s team managed to beat their previous personal best of 2010, where they managed to surpass the magic limit of 10 terabits per second, which is actually a data rate of 10,000 billion bits per second. Why is there such a large improvement in less than half a year? Well, that can be attributed to a new data decoding process, where orthogonal frequency division multiplexing (OFDM) is applied to record data encoding.
This just goes to prove that physical limits are yet to be exceeded even at extremely high data rates, all without consuming any more energy than is required.
