Ultra-fast fiber sets global speed record: 1.02 petabits per second over continental distance

Serving tech enthusiasts for over 25 years.TechSpot means tech analysis and advice you can trust Why it matters: A technological leap in fiber optics has shattered previous limitations, achieving what experts once considered impossible: transmitting data at 1.02 petabits per second – enough to download every movie on Netflix 30 times over – across 1,808 kilometers using a single fiber no thicker than a human hair. At the heart of this breakthrough – driven by Japan's National Institute of Information and Communications Technology (NICT) and Sumitomo Electric Industries – is a 19-core optical fiber with a standard 0.125 mm cladding diameter, designed to fit seamlessly into existing infrastructure and eliminate the need for costly upgrades. Each core acts as an independent data channel, collectively forming a "19-lane highway" within the same space as traditional single-core fibers. Unlike earlier multi-core designs limited to short distances or specialized wavelength bands, this fib ... Read full article.
