标题： Time-Frequency Transfer over Optical Fiber

摘要： 光学时频传输在大规模钟网络中建立了计量联系，这促进了各种应用。 基于光纤的传输得益于光纤基础设施的广泛部署，从而实现了这一优势。 在本综述中，我们概述了光学双向时频传输的进展，这些进展始于表征时频传输的稳定性。 然后，我们讨论了系统配置、关键模块、主要挑战和主流传输方法。 最后，综述展望了进一步应用于全球规模高精度钟网络的前景。 显示英文摘要

摘要： Optical time-frequency transfer establishes the metrological linkage in large-scale clock networks, which facilitates various applications. Fiber-based transfer benefits from the abundant deployment of fiber infrastructures to achieve this advantage. In this Review, we provide an overview of the advances in optical two-way time-frequency transfer, which began with characterizing the time-frequency transfer stability. Then, we discuss the system configuration, key modules, main challenges, and mainstream transfer methods. Finally, the Review concludes with an outlook on further applications toward global-scale high-precision clock networks.
