In that trial, researchers moved 72 terabytes of data to Hubei province in about 1.6 hours across a route of roughly 1,000 kilometers. Based on the published figures, that roughly works out to a throughput close to 100 Gbps

That’s exactly 100Gbps, not “roughly … close to.” The fact that the figures work out exactly like this is probably because one of those original figures was already calculated from an estimate of the link speed but the author of this article didn’t realise it.

It’s hardly news-worthy though, since the current data transfer speed record is held by Japan who achieved 1.02 Pbps over 1800km in April this year. That’s 10,000 times faster.
