摘　　要：为了适应高精度光纤时频传递与光纤通信网融合的发展趋势,对光纤通信网中常用的波长选择开关(WSS)的时频传递性能进行了研究。基于波分复用、单纤双向还回和光学真时延补偿的方案搭建了一套高精度光纤时频传递系统,研究了WSS的输出端口、输出损耗和输入光信号的偏振态变化对时频传递性能的影响,并在此基础上研究了含WSS的时频传递系统的开闭环特性以及闭环情况下WSS的动态切换对时频传递系统的影响。实验结果表明,WSS的引入对光纤时频传递性能的影响是可以控制的,证实了在含WSS的商用光纤通信网中进行高精度时频传递是可行的。To adapt to the development trend of combining high precision fiber time-frequency transfer with optical fiber communication network, the time-frequency transfer performance of wavelength selection switch （WSS） which is commonly used in optical fiber communication network is studied. A system with high precision fiber time-frequency transfer is established based on the wavelength division multiplexing, bidirectional return and optical real time delay compensation scheme. The effects of output ports, output loss and variation of polarization state of input optical signal on the time-frequency transfer performance of the system are discussed. In addition, the open-loop and closed-loop performance of time-frequency transfer system including WSS and the influence of dynamic switching performance of WSS under closed-loop on the time-frequency transfer system are studied. The experimental results show that the effect of WSS on the fiber time-frequency transfer performance can be controlled, and it is proved that the high precision time-frequency transfer in the commercial optical fiber communication network with WSS is feasible.
