摘　　要：光纤是远距离传输时钟信号的重要途径之一,光纤振动会对光纤的偏振模色散产生变化,从而影响时钟信号的传输性能。为了降低光纤振动对时钟传输的影响,详细分析了光纤振动对时钟信号传输劣化的原因,提出了一种新的抗光纤振动传输技术方案,并通过实验方法验证了该技术方案可以改善相位噪声10~15 dB。Fiber is one of the important ways to transmit clock signal over a long distance.The vibration of fiber will change the polarization mode dispersion of fiber,which will affect the transmission performance of clock signal.In order to reduce the impact of fiber vibration on clock transmission,the reasons of clock signal transmission degradation caused by fiber vibration are analyzed in detail,and a new anti fiber vibration transmission technology scheme is proposed.The experimental results show that the phase noise can be improved by 10~15 dB.
