It's been about eight months since the Vera Rubin Observatory (VRO) saw first light. Now the telescope is scanning the night sky to detect transient changes and sending alerts to astronomers and ...

Thanks to Fink, a software package created by two CNRS engineers, it is now possible to track millions of transient celestial phenomena observed in the sky by the Vera C. Rubin Observatory in Chile, ...

Phlux Technology, a manufacturer of avalanche photodiode infrared sensors, will exhibit its Aura family of Noiseless InGaAs APDs at SPIE Photonics West, San Francisco, January 20-22, 2026. The company ...

EXFO, the communications industry’s test and measurement experts, announced availability of the industry’s first hollow core fiber optimized OTDR (optical time domain reflectometer) with ...

Light beamed through fiber can be used to test and monitor fiber networks. It is also increasingly being used as a sophisticated sensor for the world around the fiber cable. On the surface, an optical ...

As fibre optic networks grow in both size and complexity, so does the need to monitor their performance in real time. The Optical Time Domain Reflectometer (OTDR) is a familiar instrument used by ...

Abstract: A novel Brillouin optical time-domain reflectometer using an adaptive frequency analysis (AFA) algorithm enhances spatial resolution by 2.5 times at 10 MHz frequency resolution compared to ...

A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...
