Japan breaks the world record internet speed record: 1. 02 petabits per second via fiber optics, 4 million times faster than broadband. Breakthrough uses 19-core optical fiber, matching current cable thickness but with 19x the capacity. The achievement yielded a capacity–distance product of 1. That rate is about four million times higher. Japan's latest fiber-optic breakthrough has shattered speed expectations—imagine streaming the entire Internet Archive in under four minutes. 127 mm strand, researchers hit 125,000 GB/s across 1,120 miles, roughly from New York to Miami. With speeds like this, we're looking at faster streaming and a whole new world for global data. The current record speed held by researchers at Japan's Network Research Institute of Information and Communications Technology (NICT) demonstrated a fiber data transmission speed of 1.
