Researchers at the University of Karlsrushe, Germany, beat the world record for data transfer to achieve the remarkable mark of 26 terabits per second using a single laser beam into a fiber optic cable - speed equivalent to transfer the contents of 700 DVDs in time you take to say "I want".
According to the researcher Wolfgang Freude, co-author of the experiment, this performance was achieved using a technique called "fast Fourier transform, "in which a single light beam is divided into 325 different colors that carry their own sequence information. The previous record belonged to the same team, which last year managed to reach the milestone of 10 Tbps in their laboratories.
The team fabricated two optical processor capable of reading the encoded information of lasers. "26 terabits per second are able to simultaneously transmit up to 400 million connections or entire contents of the Library of Congress American in 10 seconds, "added the researcher.
"Until now the only limiting the transfer speeds of optical fiber lasers are the amount of available" full Freude, saying that "networks of 100 Tbps have been demonstrated by other laboratories. " "But the difference is that we we had only a single laser, while these other experiments were 370, which is incredibly expensive and costly, "he recalls. ". In his view, the creation of your team is an important step toward "a new generation of high-speed Internet for the future. "
