Evaluation Parameter for Self-Healing FBG Sensor Networks After Multiple Fiber Failures

Blog Article

Quantitatively evaluating the reliability PROSTCARE PROST-ACTION of fiber Bragg grating (FBG) sensor networks becomes problematic as the number of working fiber failures increases in dedicated protection mode.To solve this problem, a signal attenuation rate (SAR) of the sensor system is proposed to evaluate self-healing capabilities after increased working fiber failures.We analyze the influencing factors and calculate the theoretical values of SAR under different network states for values of split ratio a = 0.1, 0.

5, and 0.9.Our theoretical model was experimentally demonstrated using an FBG sensor network with four sensors.The results of our calculations using this model agree with Security our experimental results.
