摘　　要：设计实现了用于光纤时间传递系统的BEDFA,理论分析了该BEDFA对长距离光纤时间传递性能的影响并进行了相应仿真,得出每增加一个BEDFA时间系统精度降低50ps、稳定度降低5×10-11/s(-25dBm接收光功率和典型参数)的结论。利用环回法时间传递样机设计相应实验对理论进行了验证。BEDFA applied in time transfer system is developed,and the impact to long-distance time transfer characteristics is analyzed and simulated.It find that the precision of time transfer degrades by 50 Pico-seconds and the stability degrades by 5×10-11（-25dBm receiving optical power and typical parameters） as an additional BEDFA is added.The theory is validated by corresponding experiment which is designed by means of round-trip method.
