Experimental demonstration of thermal characteristics of jacket optical fiber. a Two-fold coincidence probability and b corresponding shifted phase as a function of heating temperature of sensing fiber versus different frequency detunings. The shaded regions bounded by two smoothed curves represent the standard deviation of experimental results estimated by statistical methods assuming a Poisson distribution
