A fiber-optic sensor is a that uses either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). It is used around the world to monitor power stations, telecom networks, railways, roads, bridges, international borders, critical infrastructure, terrestrial or subsea power cables or pipelines, and downhole applications in oil, gas and enhanced geothermal electricity. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. This paper introduces the basic principles of several commonly used optical fiber sensors and the progress of optical fiber sensors in the monitoring of physical, mechanical, and chemical parameters and demonstrates the applications of optical fiber sensors in infrastructure. In this exploration, we will delve into the operational principles, benefits, and. Light is trapped inside the core and travels along the fiber by bouncing off the interfaces with the cladding.

This paper presents a comprehensive review of AI-enhanced OFS technologies, encompassing both localized sensors such as fiber Bragg gratings (FBG), Fabry–Perot (FP) interferometers, and Mach–Zehnder interferometers (MZI), and distributed sensing systems based on Rayleigh . The integration of artificial intelligence (AI) with optical fiber sensing (OFS) is transforming the capabilities of modern sensing systems, enabling smarter, more adaptive, and higher-performance solutions across diverse applications. In 2023, researchers turned submarine cables into earthquake warning systems and gave electric vehicles "optical nerves" to prevent battery failures. Associate Professor Faisal Nadeem Khan from the Institute of Data and Information has recently published a perspective article entitled Non-technological barriers: the last frontier towards AI-powered intelligent optical networks in Nature Communications.
