论文摘要
提出了一种相关光学时间域反射量（COTDR）方法，该方法以几个picseconds的精度来测量传播延迟。使用10 GBIT/s的测试信号数据速率以及采用互相关和脉冲拟合技术来实现此精度。在本文中，我们介绍和评估基本信号处理步骤，研究测量精度，并讨论用于监视链路延迟和长纤维跨度的色彩分散以及温度传感应用的应用。
A correlation optical time-domain reflectometry (COTDR) method is presented, which measures the propagation delay with an accuracy of a few picoseconds. This accuracy is achieved using a test signal data rate of 10 Gbit/s and employing cross-correlation and pulse fitting techniques. In this paper we introduce and evaluate the basic signal processing steps, investigate the measurement accuracy, and discuss applications for monitoring link delay and chromatic dispersion of long fiber spans as well as temperature sensing applications.
