Japan's National Institute of Information and Communications Technology (NICT) broke the global internet speed record.

It achieved an astonishing 1.02 petabits per second. How fast is that speed?

This is fast enough to download the complete Netflix library in one second.

Remember that 1.02 petabits per second is: One Billion, Twenty Million Mega Bytes Per Second (1,020,000,000 Mbps). This creates a staggering speed gap between cutting-edge research and regular internet experiences around the world. It was achieved through innovative fiber optic technology developed by NICT's Photonic Network Laboratory in collaboration with Sumitomo Electric and European researchers that utilized a specialized 19-core optical fiber cable, which created a 19-lane data superhighway while maintaining the standard 0.125 mm diameter as conventional cables. This compatibility with existing infrastructure makes implementation feasible without requiring complete system overhauls. 

Researchers sent signals through 19 separate loops each measuring 86.1 km repeating the journey 21 times to achieve the impressive 1,808 kilometer transmission distance. The total data transferred per second per kilometer reached 1.86 exabits—the highest value ever recorded. This long-distance achievement (equivalent to traveling from London to Rome or Missouri to Montana) demonstrates the technology's viability for practical, intercontinental data transmission networks.

Average users worldwide experience significantly slower connections. Singapore leads consumer broadband rankings at 345.33 Mbps, followed by the United Arab Emirates (313.55 Mbps) and Hong Kong (312.48 Mbps). In the United States, the national average reached 214 Mbps in 2025, with significant regional variations—Delaware enjoys the fastest speeds at 246.95 Mbps while Idaho lags at just 124.57 Mbps. India's digital landscape has evolved rapidly, with mobile data consumption reaching 27.5 GB per user monthly in 2025, nearly double the global average, despite relatively modest fixed broadband speeds averaging around 61.66 Mbps.

This context highlights Japan's revolutionary petabit-class achievement, operating at speeds millions of times faster than what's currently available to consumers; a transformative milestone for next-generation communications infrastructure. The breakthrough will be a foundation for post-5G systems to address our growing intercontinental data transfer needs.

This innovation arrives at a critical time with experts viewing the achievement as key to supporting the explosive growth in AI applications, cloud computing, and immersive technologies. Practical implications extend beyond raw speed metrics to changing the way that we interact with digital content. With capacity to transmit over one million gigabytes per second, this technology allow users to quickly download massive 150GB video games or stream millions of ultra-HD videos simultaneously increasingly important as average monthly data consumption continues to rise globally.
