A team of researchers from University College London, in collaboration with Xtera and KDDI Research, have set a new internet speed record. Led by Dr. Lidia Galdino, the team achieved a data transmission speed of 178 TB per second (or 178 MB/s), which is fast enough to download the entire Netflix library in less than a second. . . The new Internet speed record is a fifth faster than the previous best (set by a team of engineers in Japan) and twice as fast as any currently active system. The figure achieved by academics is also close to the theoretical speed limit for data transmission, as put forward by the American mathematician Claude Shannon in 000.
Internet speed record
The new record speed was achieved by pushing the data into a much wider wavelength range than is used in modern fiber optics. The current Internet infrastructure is based on a spectral bandwidth of 4,5 THz, but the research team used a massive bandwidth of 16,8 THz. To make this possible, the academics combined various amplification technologies to increase signal strength and optimize speed using the newly developed Geometric Shape (GS) constellations (described as "patterns of signal combinations that explode at best phase, luminosity, and polarization properties of light.”) “While next-generation cloud data center interconnects are capable of carrying up to 35 terabits per second, we are working with new technologies that make a more efficient use of the existing infrastructure, making better use of the fiber optic bandwidth and enabling a world record speed of transmission," explained Dr. Galdino. "Internet traffic has grown exponentially over the last few 10 years and all of this growth in data demand is tied to the drop in cost per bit, the development of new technologies is essential to sustain this downward trend in costs while meeting future performance demands of data. data, which will continue to increase. "The advantage of the new technologies used by the UCL team is that they could sit on top of existing internet infrastructure, and not be too expensive to implement, meaning that part of the performance gain could be passed on to the user. end in the not-too-distant future.In the meantime, if you're looking for ways to boost speed, check out our ultimate guide to boosting Wi-Fi.
