Japan sets new internet speed record, capable of downloading the entireWikipedia in one second

Japan sets new internet speed record, capable of downloading the entireWikipedia in one second.

Researchers in Japan have achieved a major milestone in data transmission: 1.02 petabits per second – equivalent to over 1 million gigabytes per second – sent through a 1,123 miles (1,808 km) standard-diameter fibre optic cable.

The key innovation lies in a 19-core optical fibre, with each core functioning as an independent data channel. Combined with an advanced amplification system operating in both the C and L optical bands, the setup maintained high signal integrity over long distances – a major limitation in previous high-speed systems.

At this speed, transferring large-scale content becomes nearly instantaneous. Think:
85,000 4K movies
12,000 full-size games
