光纤传递链路中相位噪声探测是基于光纤的精确射频标准传递系统中重要组成部分。为解决光纤链路相位噪声探测中节点反射干扰的问题，本文基于广义非线性薛定谔方程，理论上研究了窄带光学频率梳在色散位移光纤中的非线性光学传播特性。在理论分析的基础上，结合密集波分复用架构，提出了一种基于锁模光学频率梳进行光纤传递射频信号的相位噪声探测新技术，克服了节点反射干扰，给出了初步实验验证。

Precisely detecting phase noise in the optical fiber is one of the core techniques for high resolution microwave dissemination based on optical fiber link .In order to solve the problem that unwanted reflections from fiber interconnectors greatly reduce the accuracy of phase noise detection , we propose and demonstrate a spectrally shifted optical feedback scheme integrated with wavelength division multiplexing technique for pre -cise phase detection based on nonlinear propagation of narrow band optical frequency comb in dispersion shif -ted fiber .Theoretical and preliminary experimental results show that the proposed approach efficiently suppres -ses the reflection noise .
