【Abstract】 A novel in-service monitoring scheme based on composite frame and correlation operation processing for OTN system fiber link is proposed. The scheme utilizes the M sequence and the OSC service data to form a composite frame. The structure of composite frame can be adjusted flexibly to realize both large dynamic range and high spatial resolution. The dynamic range can be improved by correlation operation processing. Compared with other schemes, it has larger dynamic range and could not incur service signal waveform distortion. The system parameters can be adjusted flexibly according to the OSC service data to take full advantage of OSC channel capacity. The effectiveness of the scheme is verified by simulation and experiment.更多还原
