What BBN said about it

Hank Ledger · Lead AnchorA Chinese team says it moved 3. 2 petabits per second over optical fiber, in real time.

Dale Bearman · Chief Skeptic & ContributorThat's more than twenty thousand 4K movies in one second, Tom's Hardware says, and nobody has twenty thousand movies they want to watch.

Hank Ledger · Lead AnchorIt beats the same team's own record from earlier this year, 2. 5 petabits, by almost thirty percent.

Dale Bearman · Chief Skeptic & ContributorHere's my problem. The link was about ten kilometres long.

Dale Bearman · Chief Skeptic & ContributorThe Hubei government website says the speed could serve 3. 2 million households with gigabit broadband at once, if rolled out. That 'if' is carrying three million households.

Hank Ledger · Lead AnchorIt's a real result, though. They decoded the data live, in modules built along commercial lines.

Dale Bearman · Chief Skeptic & ContributorTen kilometres. Lab fiber has already hit 5. 29 petabits.

Hank Ledger · Lead AnchorSo the record is real and the rollout is a maybe. Bonk-o-Meter says Moderately Bonkers.

Dale Bearman · Chief Skeptic & ContributorThree point two million households, and my building still can't keep a video call alive.

Dale Bearman · Chief Skeptic & ContributorI'd be the first one on the list for the 'if'.
