Paper Abstract

In this paper, we compare the performance of a Correlation Brillouin Optical Time Domain Analysis (CBOTDA) system using bipolar Golay complementary pairs and unipolar Optical Orthogonal Code. Our simulation studies show that the spatial resolution supported by both schemes are comparable, but the Golay code is preferred due to better peak power to average power ratio (PAPR). We proceed to experimentally demonstrate the detection of a temperature event at the end of a 50 km long sensing fiber using Golay complementary pairs.
