Distributed Fiber Optic Sensor Market: How Fiber Sensing Is Making Railways Smarter and Safer
Distributed fiber optic sensing (DFOS) is a technology that turns an ordinary optical fiber into thousands of individual sensors along its entire length. Instead of installing separate sensors at fixed points, engineers send light pulses through the fiber and analyze how that light scatters when it encounters changes in temperature, strain, vibration, or acoustic activity. The result is...
