摘　　要：阐述了利用单通道双向放大器(single path bidirectional amplifier,SPBA)拓展时间伺服传递距离的基本原理,利用单通道双向放大器将授时距离拓展到200km,搭建的实验系统完成了双向时间比对和终端时频信号的伺服重生,授时同步误差峰峰值为507ps。Basic principle of extending disciplined time transfer distance based on single path bidirectional amplifier has been expatiated. By using single path bidirectional amplifier, the experiment of two-way time transfer on 200 km optical fiber has been realized. Disciplined time on remote station has been regenerated.The peak-to-peak value of synchronization error is 507 ps.
