Data speed record has been broken

German scientists at the Karlsruhe Institute of Technology (KIT) have announced that they have broken a data speed record by sending 700 DVDs worth of data in one second, over a single laser beam.

That’s 26 terabits sent over 50 kilometres on a single laser beam in one second.

Professor Juerg Leuthold from the Institute was proud of the accomplishment, relishing in the fact that this speed sets a new world record. “With 26 terabits per second, you can simultaneously transmit up to 400 million telephone calls per second,” he said.

The data was coded via a new system known as orthogonal frequency-division multiplexing (OFDM) where a single laser beam is divided into separate colour streams in order to fit more data in.

This new technology paints a picture of a future world in which we don’t have to worry about internet speeds, sizes of files or number of users. Within a second you can send and receive Bluray size movies, your whole catalogue of music and a complete library of books at the push of a button.
