World’s fastest internet speed from a single optical chip

A research team has recorded the world’s fastest internet speed from a single optical chip of 44.2 Terabits per second.This technology has the capacity to support the high-speed internet connections of 1.8 million households in Melbourne, Australia, at the same time, and billions across the world during peak periods.
Demonstrations of this magnitude are usually confined to a laboratory. But, for this study, researchers achieved these quick speeds using existing communications infrastructure where they were able to efficiently load-test the network.
 

Nokia, Etisalat conduct single-carrier terabit optical transmission field trial

Nokia and Etisalat have conducted the first field trial of single-carrier terabit optical transmission. The collaborators conducted the 1-Tbps transmission on a deployed fiber-network in the United Arab Emirates (UAE), transmitting a total of 50.8 Tbps via multiple wavelengths, each with a net information rate of 1.3 Tbps, over a 93-km fiber route. The optical transmissions were based on a single optical carrier operating at 100 Gbaud and Nokia Bell Labs-pioneered probabilistic constellation shaping (PCS).
