In 2024, Japan set a new internet speed world record, achieving 402 terabits per second using standard commercial optical fiber. This speed is sufficient to download 50,000 full HD movies in one second.

Fiber-optic sensor reads strain through electrical signals, skipping optical analyzers
Scientists have demonstrated a new fiber-optic sensing method that detects strain and displacement by reading interference patterns directly in the electrical spectrum of a photodetected signal. The approach uses a polymer optical fiber-based single-mode–multimode–single-mode (SMS) structure, in which multimode propagation creates relative modal delays that appear as measurable dips in the electrical-frequency domain. Their research was published in the IEEE Sensors Journal on April 27, 2026. "The key point of this work is that the interference pattern appears directly in the electrical domain," said corresponding author Associate Professor Yosuke Mizuno of Yokohama National University. "This gives us a new way to read out fiber-optic sensor signals without relying on conventional optical-spectrum interrogation, while still exploiting the rich modal behavior of polymer optical fibers."

Working on a fiber optic jellyfish dress, using fiber optic fabric from Lumisonata! This is just pinned on my dressform to get an idea of how everything is looking. I’ll be finishing up the bodice next and after that I’ll be making some jellyfish puff sleeves!
