Following the enormous development of the fibre Bragg grating(s) (FBG) sensor technology in the recent years, different kinds of fibre optic sensors (FOS) with advanced faculties were designed and matured to sense various parameters, including temperature, radiation, rotation, strain, acceleration, vibration, humidity, refractive index (RI) and so on. In this chapter, we will detail and review the main applications of FBG sensors while putting focus on the communications field.
