Physicists from the University of Oregon have successfully changed the color of individual photons within a fiber optic cable. They were able to do so by focusing a dual-color burst of light from ...

To use a telecommunication cable as a seismic sensor, researchers inject light from a laser into one end of the optical fiber and monitor the light that exits the other end. When a seismic wave ...

Here’s how.] When hung on a utility pole, fiber optic cables can be used as a sensor to detect changes in temperature, vibrations, and very loud noises. This emerging technology is called ...

One major advantage to DAS is that fiber-optic cables can be many kilometers long, and a single one can act like a network of thousands of sensors covering every meter along its path. Conversely ...

Each optical fiber span acted as a sensor, with up to 12 sensors implemented along the cable. This groundbreaking research could potentially enable the monitoring of vast areas of the ocean floor ...
