设计了一种基于FPGA、温控光纤延迟线和压电陶瓷(PZT)光纤延迟线的光纤频率传递主动光学相位补偿系统,设计和制作了大动态范围温控光纤延迟线及其驱动电路。在基于Round-Trip方案的20kin光纤频率传递实验系统中进行了测试。
This paper designed an active optical phase compensation system for frequency transfer over optical fiber based on FPGA, temperature-controlled fiber delay line and PZT delay line.A temperature-controlled fiber delay line with a large dynamic range and its drive circuit are designed and implemented. The tests are carded out in a round-trip based frequency transfer experimental system over 20km optical fiber link.
