Abstract :
A novel method for fiber-fault detection with chaotic laser theory is demonstrated and is verified by simulation and experimental results. The chaotic light is generated by optoelectrical feedback, and the simulation results show that the RF spectrum of the generated chaotic light is broad and flat. The PSLR and the FWHM of the autocorrelation curve are 20 and 0.01ns, respectively. Experimental results show that this approach is able to detect simultaneously the location of multi-fault in single/multiple fiber channels. The space resolution is 0.9mm, and the location of fiber fault in an optical network with two-level division light is able to be detected. The method has a significant practical value for the detection and location of the fiber-faults in the optical access network.
