Scientists at Karlsruhe Institute of Technology in Germany have achieved the world’s fastest data transmission at 26 terabits per second (Tbps), using a single laser, over a 50km fibre.with low energy consumption.
it's fast enough to transfer the entire Library of Congress in ten seconds.
"this is the largest line rate ever encoded onto a single light source,” said the scientists in the journal Nature Photonics.
According to ZDNet, the experiment used a single laser to create a long range of pulses, which are known as ‘frequency combs’.
These pulses were then magnified into 325 colour channels via a method called ‘inverse fast Fourier transform,’ before being sent down a 50km cable. Once it reached the other end, an optical fast Fourier transform encoded it back into data.
According to a co-author of the journal Wolfgang Freude,However, the 26 Tbps data transfer is not actually the fastest.
“Already a 100 terabits per second experiment has been demonstrated,” he said, adding that this required 370 lasers, which is highly expensive.
