⚡ Scientists in Japan Shatter Internet Speed Record with 1.02 Pbps Breakthrough
🚀 What Happened?
A research team at Japan’s National Institute of Information and Communications Technology (NICT), working with Sumitomo Electric and European partners, achieved a world-record internet speed of 1.02 petabits per second (Pbps)—equivalent to over 125 terabytes every second—using a specially engineered 19-core optical fiber cable spanning 1,808 km gigonomist.com+9www.guru3d.com+9Reddit+9Navbharat Times+15The Indian Express+15www.ndtv.com+15.
