Blistering 402 Tb/s fiber optic speeds achieved by unlocking unused wavelengths

Amid 6G promises, scientists find a way to wring incredible speeds out of boring old fiber
What just happened? Scientists in Japan have just blown the doors off what we thought was possible with conventional fiber optic cables. A team led by the country's National Institute of Information and Communications Technology has set a new world record by transmitting data at a blistering 402 terabits per second through an existing fiber optic line. That's fast enough to download over 50,000 HD movies in a single second.

In nuclear fusion milestone, Japan unveils the world's largest reactor

The system is an important step forward to harnessing fusion as a clean energy source
Forward-looking: Fusion differs from fission, which is used in nuclear power plants, and it is based on the same principle that powers the Sun and stars as the hydrogen nuclei fuses into helium, releasing light and heat. Also, unlike nuclear power, fusion is intrinsically safe in that the reaction stops when the fuel supply or power source is shut down. Nor does it generate high-level long-lived radioactive waste.
