1 million Gbps: the latest Internet was tested in Japan

Researchers from Japan have set a new data transfer speed record – 1.02 petabits per second (Pbps)

. What's even better is that the breakthrough has been achieved using fiber optic cables, which should be compatible with existing infrastructure. Discuss

Even NASA will get “only” 400Gbps when ESnet6 rolls out in 2023. At 1 Pbps, it is theoretically possible to broadcast 10 million channels in 8K resolution, the team claims.

A new record was set by researchers fromJapanese National Institute of Information and Communications Technology (NICT) using new technologies: the optical fiber contains four cores – glass tubes through which signals are transmitted, – instead of the usual one. Bandwidth is expanded to a record 20 THz using a technology known as wavelength division multiplexing (WDM).

This band consists of 801 wave channels,distributed over three ranges. Using some other new optical amplification and signal modulation technologies, the team achieved a record speed of 1.02 Pbps, transferring data over 51.7 km of fiber optic cables.
