The process of establishing a damage detection and characterization method for engineering structures is known as structural health monitoring. SHM entails monitoring a system over time with the help of periodically sampled response data from a variety of sensors. Bragg reflector, which is a discrete spectrally reflecting carved in centre of optical fibre under the high intensity source is known as a fibre Bragg Grating sensor. Its purpose is to investigate how the Fibre Bragg Grating Sensor (FBGS) monitors the temperature on power lines. The main aim is to change the pressure, strain and temperature data through FBGS, BOTDR (Brillouin Optical Time Domain Reflectometry) makes use of spontaneous Brillouin scattering, which has a low backscatter power level. To identify the weak reflection signal, a sophisticated detecting mechanism must be applied. We demonstrated that utilizing Optisystem, we can module the optical spectrum, allowing us to monitor the whole FBG.
