Abstract

In this work, Fiber Bragg Grating (FBG) is characterized as temperature sensor because of its sensitivity to temperature, thus making it a potential device to perform pipeline water leakage inspection. Bragg wavelength □_B is measured by tunable laser source (TLS) as light source and optical spectrum analyzer (OSA) is used to observe the reflected Bragg Wavelength at temperature from 24 °C to 40 °C. Analysis is carried out to define the relationship of □_B with temperature based on the collected data. The temperature sensitivity of 9.2 pm/°C and 9.8 pm/°C was obtained for FBG1 and FBG2 respectively.
