Record-breaking laser transfers 26 terabits per second!


A single laser beam has been used to transfer 26 terabits of data in one second by researchers in Germany.
The extreme data transfer was the equivalent of 700 DVDs being transferred in one second, speeds that we mere mortals can only dream of as we sit drumming our fingers on the desk while ripping a single CD, watching the progress bar slowly creep along the screen.
"The problem was they didn't have just one laser, they had something like 370 lasers, which is an incredibly expensive thing. If you can imagine 370 lasers, they fill racks and consume several kilowatts of power."
Here's the complicated bit The secret to the single laser transfer was using very short pulses in a 'frequency comb', a number of different colours of light contained within the single beam.
