World record in data transfer – New Technology

Danish scientists have broken a new world record for data transfer. The trick is a new type of fiber.

43 terabits per second, sent by a single laser over a single fiber. High Speed ​​researchers Leif Katsuo Oxenlöwe and Hao Hu at the Technical University of Denmark has once again broken the world record in data transmission. The previous record of 32 terabits was three years ago by researchers at the German Technical University in Karlsruhe.

record is equivalent to a data rate of 5.4 terabytes per second. Transferring a terabyte from a hard drive with the technology would, in other words, go 0.2 sec

To set the record, the researchers used a new type of fiber-optic cable developed by the Japanese telecom giant NTT. The fiber contains seven different grains in which light travels, yet they have no bigger in diameter than a fiber with a single core. The successful result has led to the NTT will now be commercializing fiber.

The breakthrough is important not only to increase the transmission capacity, but also to keep energy use down. Data traffic over the Internet is increasing by 40 to 50 percent per year, and with the energy consumption and contribution to carbon emissions. Finding a solution that provides higher bandwidth while reducing energy consumption is important, the researchers point out in a press release.

It is not the first time the Danish fotonikgruppen beats the world record for data transfer. The first time was in March of 2009. Pumping out world number four.
