【摘要】 高稳定时间频率（简称“时频”）传递是时频系统两种核心技术之一。基于光纤可实现高精度、大范围传递，是地面时频传递的最佳选择。本文介绍光纤时频传递基本原理，以光纤光学频率传递为例，深入阐述了系统噪声补偿方法。针对目前时频传递设备因采用分立光电子器件而存在的不足，探索研究了光电子集成芯片设计方法，展示了集成化的优势。最后，总结了国内外光纤时频传递研究进展，并对其未来发展进行了展望。更多还原

【Abstract】 Stable time and frequency transfer is one of the two core technologies in time and frequency infrastructure systems. Optical fiber enables high precision and long-distance transfer, making it the best choice for terrestrial time and frequency transfer. In this study, we introduce the principles of fiber-optic time and frequency transfer and elaborate on the phase noise compensation methods using optical frequency transfer as an example. Addressing the limitations of current time and frequency transfer equipment that uses discrete optoelectronic devices, we explore and study the design approaches for optoelectronic integrated chips and demonstrate the advantages of photonic integration. Finally, we review recent progress in fiber-optic time and frequency transfer globally and present prospects.更多还原
