Story summary

A Japanese team set a world record in fiber optics, achieving 1.02 petabits per second over 1,123 miles.
Their optical fiber design accommodates 19 light paths within a 0.005-inch cladding size.
This innovation minimizes power loss and crosstalk, facilitating high data rates over long distances.
The experiment used 19 synchronized loops and 180 wavelengths across C and L bands.
The system incorporated 16QAM modulation and MIMO technology for improved signal separation and error correction.
