There are reports of IT sabotage, cyber espionage, and other acts of hybrid warfare almost every day. Communication networks ...

Quantum repeaters for fiber-based, long-range quantum communication We all know repeaters ... Perhaps it will even prove possible to create optical quantum repeaters that can operate without ...

To the best of our knowledge, this is currently the longest distributed optical fiber sensing system without in-line repeater. The system offers potential applications in fields such as perimeter ...

Quantum repeaters for fiber-based, long-range quantum communication We all know repeaters as devices that tend to lurk in ... Perhaps it will even prove possible to create optical quantum repeaters ...

Abstract: This article presents a portable optical fiber sensor (OFS) design for continuous liquid level measurement, fabricated using two pieces of bare polymer optical fibers (POFs). The proposed ...

In the same way subsea cable systems have repeaters every ~100km to amplify signals being sent between locations, in-line amplifier (ILA) sites amplify signals sent along terrestrial fiber. As fiber ...

Ukraine has, for some time, fielded large "mothership" drones that can carry and eventually deploy a set of smaller attack ...

In the Optica Publishing Group journal Applied Optics, the researchers describe their new sensor, which uses an optical fiber and an optical phenomenon known as localized surface plasmon resonance.
