介绍了光纤双向时间传递的基本原理和系统组成，通过对信号传输链路分析，推导出了影响时间同步精度的误差来源。详细分析了来回光纤链路不对称性、光器件处理、时间间隔测量等引入的误差对时间同步精度的影响，从理论上计算出各项影响因素引入误差的量值。提出了降低误差、提高系统同步精度的方法。通过理论分析和计算得出光纤双向时间传递系统同步精度可达亚纳秒量级。

The basic principle and system composition of two-way optical fiber time transfer( TWOFTT)method is described. The factors influencing the synchronous precision are deduced through analysis of signal transfer link. Asymmetry error of signal two-way transfer link,optical device processing error and time interval measurement error are analyzed. The magnitude of each error factor is calculated through theoretical analysis. The methods for reducing every error are proposed. The time synchronization precision of TWOFTT system can reach subnanosecond magnitude through theoretical analysis and calculation.
