Abstract :
In this paper, we review the correlation detection technique (CDT) for fiber faults diagnosis and describe our chaotic signal- and communication signal-based correlation detection schemes in passive optical network (PON). The results show that spatial resolution of 2cm and dynamic range of about 20.8dB can be achieved when chaotic signal is used. Utilizing communication signal itself as the probe light, we achieve a spatial resolution of 8cm and detection range of above 23km.
