silicon photonics fiber optics petabits per second

Silicon Photonics: 1.84 petabits per second sent through a single photonic chip/fiber optic cable combo

A new transfer record has been achieved using a single fiber optic cable
Forward-looking: Scientists from Copenhagen were able to transfer twice the size of everyday's Internet traffic through a single fiber optic cable, an unprecedented feat that could bring silicon photonics one step closer to reality with massive improvements for everyone.

Damaged European undersea cables impact internet connectivity worldwide

Why it matters: Multiple undersea cables in the south of France were cut overnight, making Internet access unreliable globally. Engineers fixed one broken link, and investigations are still ongoing. Fingers have been pointed at Russian submarines because of the Ukraine conflict, but investigators have not yet found any evidence supporting this assumption.

Fujitsu's new optical system can transmit data at 1.2 Tbps per wave

Fast enough to transfer six Blu-ray discs in one second
Something to look forward to: Fujitsu has developed an optical transmission technology capable of delivering up to 1.2 Tbps per optical wave, or the equivalent of six Blu-ray discs (25 GB) per second. The new tech is superior to traditional optical networking solutions at virtually every avenue.
