New data transmission record set

Even if you have fast internet at home, you'll be far behind the new data transfer record: 1.02 petabits per second.

That's one million gigabits per second. Japan's National Institute of Information and Communications Technology (NICT) established the record by sending data 51.7 kilometres

Researchers reached the new data transfer speed record using an optical fibre network comparable to internet infrastructure. Researchers suggest this should make future updates simpler.

Only a year earlier, researchers from the same institution were attaining speeds a third of what they've already accomplished.
The experiment used 0.125 mm multi-core fibre (MCF) and WDM

Beyond 5G, data flow from new information and communication services is likely to explode, according to a NICT news release.

"This finding may assist create new communication systems to serve bandwidth-intensive applications."
The research was presented at CLEO 2022.
