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 □ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">B</sub> 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 □ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">B</sub> 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.
