Do you know the fastest fiber

On August 3, 2014, researchers at the Technical University of Denmark developed a new type of fiber optic cable. The network speed of a single fiber optic cable with a single laser transmitter can reach 43 Mbit/s. This is the fastest network speed in the world. It only takes 0.2 milliseconds to download a 1GB movie, which can be said to be completed in the blink of an eye.

Previously, the fastest speed of a single fiber optic cable was 26 Mbit/s, which was set in 2011 by researchers at the Karlsruhe Institute of Technology in Germany. The Danish University of Science and Technology set a series of single-fiber cable speed records between 2009 and 2011, including breaking 1 Mbit/s for the first time. But then the light was blocked by Karlsruhe Institute of Technology.

Although the Danish University of Science and Technology uses a single-fiber cable, compared to an ordinary single-core optical fiber, this set of optical fibers contains 7 cores, and the thickness is still the same as that of an ordinary optical fiber. The world's fastest commercial single laser transmitter single fiber optic cable network connection speed is 100GB per second.
