Patcay.com – An extraordinary achievement has been made by a group of researchers in Japan in terms of internet speed. Researchers from the Photonic Network Laboratory at the National Institute of Information and Communication Technology (NICT) have recorded an internet speed of 402 terabits per second (Tbps), breaking the world record.
The research team used commercial fiber optic cables to achieve this remarkable data transmission speed. The speed of 402 Tbps is equivalent to being 1.6 million times faster than the average broadband internet speed in the United States. For comparison, as of May 2024, the average internet speed in the United States was 248.27 Mbps for downloads and 34.23 Mbps for uploads.
A speed of 402 Tbps allows for the downloading of approximately 12,500 movies in one second, and it is more than three times the speed needed to download the entire Netflix movie library.

“This latest technology is expected to make a significant contribution to expanding communication capacity and optical network infrastructure, given the high demand for internet services in the future,” said NICT.
To achieve this speed, the researchers developed a system that uses the entire transmission bandwidth of standard optical fiber and applied various amplification technologies.
According to NICT, the new method enables access to previously unused wavelength bands, which could become crucial for future telecommunications networks.
NICT emphasized that this innovative technology is expected to significantly enhance the communication capacity of optical infrastructure and meet the increasing demand for data services in the future.
The growing demand for internet and data services drives the need for greater optical transmission bandwidth. Multi-band wavelength-division multiplexing (WDM) technology has become the primary focus for researchers to further develop.
This technology expands the transmission bandwidth of optical fibers by utilizing new spectrum ranges. By employing new transmission methods on existing fiber technology, the transmission capacity can be increased.
This approach offers a promising short-term solution to extending the life of existing fiber systems without the need to increase the cost of installing new fiber infrastructure.
