The HCX drone communicates via a fiber-optic cable, making it immune to all electronic warfare. This makes it valuable in the densely-jammed airspace of Ukraine.

The Ukrainians recently captured a Russian drone which communicates via a fiber-optic link, making it jam-proof. This looks like a big headache and not just for Ukraine.

Fiber-optic drones are just one new area of focus for Ukraine's booming defense industry. The country is also producing homemade artillery, missiles, and other weapons to meet front-line demands.

As you might expect, there’s an Arduino and some RGB LED strips involved. But the key to this build is in the 16 pieces of side-glow plastic fiber optic tubing.

The D10 Expert small object counter consists of a specialized D10 Expert sensor and preconfigured PFVCA fiber-optic arrays for a 2D sensing field that detects objects that break any point of the ...

That’s pretty decent, but across the Atlantic, researchers at UK’s Aston University recently managed to coax about 1.2 million times that rate using a single fiber optic cable —a new record ...
