  • The new record speed is 178 terabits per second, which would make it possible to download the entire Netflix library in a second.
  • It’s double the capacity of any system deployed in the world, and it could be deployed on existing infrastructure by just upgrading amplifiers, without installing new cables.
  • Research authors used a wider range (16.8Thz) of light colours (wavelengths) than typically in optical fibre (4.5Thz), and optimized each wavelength individually.
  • COVID has brought the need for faster internet to light, but even regardless of the crisis, internet traffic has been growing exponentially for the last 10 years.
