10.16 Pb/s Record!
A data rate of 10 Pb/s means that 1015 bits or 1.25 million Go are exchanged every second. To give you an idea of what this magnitude entails, the entire population of Europe could watch Netflix at the same time with a connection of 10 Pb/s. 10 Pb/s is actually the world record for transmission capacity through a single optical fiber. It was obtained by the Japanese telecom operator KDDI and Sumitomo Electric Industries (SEI) in 2017, with the help of Cailabs.
