Distributed Optical Fiber Sensing (DFOS) transforms standard fiber optic cables into powerful sensors capable of detecting temperature, strain, and acoustic signals at thousands of measurement points over long distances. Unlike point sensors, they can measure and provide a continuous spatial distribution of a physical quantity, effectively creating a mapped profile of the parameter of interest. Optical fibres contained in a flexible, protective composite material are fixed to. Fiber optic distributed sensing saw the light of day in the 1980s as a breakthrough technology providing uninterrupted, EMI -immune monitoring over long distances from a single interrogator.

The sensitivity and speed of Rayleigh-based sensing allows distributed monitoring of acoustic signals over distances of more than 100 km from each laser source. Typical applications include continuous monitoring of pipelines for unwanted interference and for leaks or flow irregularities; monitoring of power cables for unwanted interference and cable faults; monitoring traffic (roads, railways and trains ), borders, and other sensitive perimeters for unusual activity; and even oil well monitoring applications. In DAS, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device.

The phase-generated-carrier (PGC) algorithm is the most widely used signal demodulation method for fiber-optic interferometer sensors (FOIS), due to its distinct advantages of high resolution, wide dynamic range, good linearity and multi-channels demodulation capability. Stimulated Brillouin scattering (SBS) suppression and phase demodulation are two fundamental issues in remote interferometric fiber sensing systems.
