Researchers set a real-time fiber record: 3.2 petabits per second over 10.3 kilometers

A joint initiative by Chinese researchers and engineers has set a new record for real-time fiber-optic communications. The team sent 3.2 petabits per second (Pbps) through a single optical fiber, topping the 2.5 Pbps mark the same group set earlier this year. The figure reflects bidirectional transmission, with traffic flowing...
