A research group at the Technical University of Denmark was able to achieve speeds of up to 43 terabits per second on a single optical fiber with only one laser transmitter.<\/p>\n
43Tbps equals a data transfer rate of around 5.4Tb\/s (5,300GBs). If you are lucky to have DTU\u2019s new fiber-optic-network, you can download 1GB movie file in just in 0.2 milliseconds, or you could transfer the entire contents of your 1TB hard drive in a fifth of a second.<\/p>\n
DTU achieved such high speeds using 7-core fiber technology- the next step of the existing \u2018optic fibres\u2019 that are currently used to provide two-thirds of the world population with the Internet. It\u2019s a single-fibre setup but has multiple individual channels that can each carry their own optical signal.<\/p><\/blockquote>\n
The main thing about this world record is DTU\u2019s use of a single laser over a single fiber. There have been plenty of network demonstrations of hundreds or even thousands of terabits (petabits) per second with multiple lasers over multiple fibres but in reality these demonstrations don\u2019t serve any purpose as commercial fiber optic networks are usually single-laser and single-fiber step-up. This means DTU\u2019s achievement might make to the real-world networks in the next few years.<\/p>\n
The previous record was 26 terabits per second set by Germany\u2019s Karlsruhe Institute of Technology in 2011. Technical University of Denmark (DTU), was the first to break the one-terabit barrier in 2009. Currently, the fastest commercial network speed maxes out at just 100Gbps. Japan\u2019s NTT is going ahead with commercial deployment of multi-core fiber in Japan.<\/p>\n","protected":false},"excerpt":{"rendered":"
