Fiber optic sensors are highly versatile and can operate over both short and extremely long distances. For standard remote monitoring applications, optical fiber cables can be interrogated up to 290 km away from the monitoring station using specialized equipment such as optical time-domain reflectometers or optical frequency domain reflectometry (OFDR) systems (Wikipedia) . This makes them ideal for applications where sensors need to be placed far from the electronics, such as in pipelines, power lines, or structural health monitoring.
Long-range fiber optic sensors are used in structural health monitoring, pipeline surveillance, high-voltage environments, and industrial automation, where placing conventional electronic sensors is impractical or unsafe (KEYENCE) . Short-range fiber optic sensors, often a few meters to tens of meters, are commonly used in factory automation and precision detection tasks. In summary, fiber optic sensors can detect over distances from a few meters to nearly 300 kilometers, with the exact range depending on the sensor design, fiber type, and measurement technique employed.

Optical fibers can be used as sensors to measure strain, temperature, pressure and other quantities by modifying a fiber so that the quantity to be measured modulates the intensity, phase, polarization, wavelength or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required. A particularly useful feature of intrinsic fiber-optic sensors is that they can, if required, provide distributed sensing over very large distances.
