Researchers create Internet so fast, you can download all of Netflix in a second

The National Institute of Information and Communications Technology (NICT) in Japan has established a revolutionary record: a data transmission rate of 1.02 sparkles per second (approximately 127,500 GB / s) over 1,802 kilometers (around 1120 miles), reports CNET.

This represents approximately 3.5 million times faster than the medium -sized large -scale large -scale internet connection, which was around 289 Mbps according to Speedtest in May 2025. At this new record speed, you can download the entire Netflix library in less than a second.

Fiber Optics with 19 cores

The recording key is a new optical fiber with 19 cores, which are installed in a cable with a diameter of only 0.125 millimeter (standard size for existing networks). Compared to conventional cables with a nucleus, this fiber transmits 19 times more data with minimal data loss due to uniform light conduction. For the transmission over the distance of 1,120 miles – comparable to New York in Chicago – the signal has been amplified 21 times.

The new record doubles more than the figure of the previous year of 50,250 GB / s. In 2023, the NICT team reached similar speeds, but only on a third of the distance. The progress of the amplification of the signal and the reduction in data loss is what has made this new beach possible.

Compatible with existing fiber cables

Technology could meet the growing demand for data worldwide, as data volumes have increased by around 50% per year according to Nielsen law.

In general, the new technology is exciting and also interesting for countries where the expansion of optical fiber stagnates, mainly because these new cables are part of existing infrastructure.

The file has not yet been verified independently, but it shows how fiber optics could further shape the future of the Internet.
