Fiber Bragg Grating Sensing Systems Performance Improvement and Assessment

The present work reports a new method to improve FBG sensing systems by minimizing dispersion effects. Moreover, a new technique utilizing communication systems’ parameters in assessing the improvement in Fiber Brag Gratings sensors is also reported. WDM techniquees with coded signaling is used. The improvement is mainly achieved by introducing DCF fiber segments to enhance the Q-parameters and Eye diagrams obtained for the system, which can be interpreted as an improvement in the sensing function. Simulations are carried out to illustrate the effect of DCF on the two factors considered.
