A chaotic-laser-correlation fiber-network-faults locator is developed. Utilizing the broad bandwidth chaotic light emitted from a laser diode with optical feedback as the probe beam, it can locate the reflection events along fiber by the correlation characteristics of chaotic light. Measurement results show the faults locator can obtain 0.5 m range-independent spatial resolution, 19.8 dB dynamic range of 4% reflection and lower than -58 dB sensitivity.
