摘　　要：现有卫星授时体系精度限制以及光网络的成熟发展,使得光纤授时成为高精度时间同步的方案之一。利用双向对比法授时原理设计光纤时间传递系统。介绍系统硬件组成,开发了一套基于Windows系统的控制测量软件,实现了整个系统的自动化控制。测量系统的时延并进行了分析,为后续补偿算法的设计提供了技术支撑。The precision constraint of the current satellite timing system and the mature development of optical networks make the optical fiber timing become one of the high-precision time synchronization schemes. The optical fiber time transfer system is designed by using the timing principle of the two-way contrast method. The hardware composition of the system is introduced,and a set of control measurement software based on Windows system is developed,so as to realize the automatic control of the overall system. Time delay of the system is measured and analyzed,which provides a technical support for the design of the subsequent compensation algorithm.
