摘　　要：针对目前点对点式光纤频率传输方式利用率不高和传输精度受限的问题进行了研究,提出了适用于大范围、远距离和多站点传输的多基地频率同步传输系统,设计了单链路分布和多链路分布两种网络结构。为提升各站点的同步传输精度,重点对中心站补偿技术和同步站补偿技术进行了方案设计。在传输频率为10MHz,光纤链路长度为25km的测试环境下,进行了无补偿测试和同步站补偿测试。In view of the low utilization rate and limited precision at the point to point frequency transfer over optical fiber, this paper puts forward multi-base frequency synchronous transmission system suitable for a wide range, long distance, multi-base transmission, and designs the multi-base single-link and multi-link net-work structure. In order to improve the transmission performance, it designs the central station compensation technology and the synchronous station compensation technology. The paper carries out the non-compensation test and the synchronous station compensation when the 10MHz frequency signal is transmitted to the remote via the 25km optical fiber.
