Abstract

Optical fiber is a communication network that the transmission and reception of information signals are using light, an optical source, optical detector, with optical fiber as a transmission medium. Besides as a medium transmission of the information signal, optical fiber can be used as a sensor. Optical fiber sensors can measure temperature, pressure, vibration, displacement, and even rotational motion. In designing optical fiber sensors, industry players must ensure the performance and strength of the product to comply with applicable standards, even with optical fiber sensor fatigue strength standards. Fatigue is a form of failure that occurs in structures subjected to dynamic and fluctuating stresses. This study mainly discussed the strength analysis of fiber optic sensors affected by the temperature change until its fatigued using the finite element method. The fiber optic sensor that received temperature change from the passing train produced thermal stress because of the constraint from both sides of it. Along with time, thermal stress that happens repeatedly produce fatigue failure for fiber optic sensor. From the results of this study, the writer obtained the lowest maximum number of cycles of 294.000 and the highest is 14.570.000 cycles. If the number of cycles is converted to time with existing data, the fastest time that the fiber optic sensor will fail is 3 years and 4 months and the longest time is 166 years and 4 months.
