Advantages of Fiber Bragg Grating Sensing Technology
This review provides a comprehensive overview of FBG sensor technology, focusing on their operating principles, key advantages such as high sensitivity and immunity to electromagnetic interference, and common challenges like temperature-strain cross-sensitivity and the high cost of. Fiber Bragg grating (FBG) sensors have emerged as advanced tools for monitoring a wide range of physical parameters in various fields, including structural health, aerospace, biochemical, and environmental applications. Following are the drawbacks or disadvantages of a Fiber Bragg Grating (FBG) Sensor: It is thermally sensitive. It is difficult to discriminate wavelength shift due to temperature and strain separately.

Distributed Acoustic Fiber Optic Sensing Technology
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.
