Khyzak REBOFF is a new Ukrainian FPV kamikaze drone with fiber optic cable for communication instead of radio. This makes it immune to jamming, the most effective protection against small drones.

The appearance of FPV drones with fiber-optic control broke away from the radio-frequency logic of modern warfare and presented new challenges for Ukraine’s Defense Forces. What are these drones, and ...

A bird’s nest incorporating fiber optic cable is a striking sign of how much debris from fiber-guided FPVs now litters the landscape of Ukraine. Other images show fields glittering with fibers like ...

Fiber-optic sensors work well in tight spots and in applications with a high degree of electrical noise, but care must be taken when specifying these critical components. Sensing part presence in ...

Russia is using fiber-optic drones to gain an advantage in the Ukraine war. These drones are harder to detect and jam than traditional drones. Ukrainian forces are adapting their tactics to counter ...

It’s always interesting to see how scientists and engineers have exploited—in the positive sense of the word—somewhat obscure, fundamental physics principles to create innovative sensors. For example, ...
