Temperature, salinity, and pressure (TSP) are essential parameters for the ocean. Optical fiber sensors (OFSs) have rapidly come into focus as an ocean detection technology in recent years due to their advantages of electromagnetic interference, light weight, low cost, and no waterproof requirement. In this paper, the most recently developed TSP sensors for single parameter and multi-parameter TSP sensing and measurement based on different OFSs are reviewed. In addition, from the practical point of view, encapsulation methods that protect fibers and maintain the normal operation of OFSs in seawater, and the response time of the OFS, are addressed. Finally, we discuss the prospects and challenges of OFSs used in marine environments and provide some clues for future work.
温度、盐度和压力（TSP）是海洋的基本参数。近年来，光纤传感器（OFSs）因其抗电磁干扰、重量轻、成本低和无需防水的优点，迅速成为海洋探测技术的焦点。本文综述了近年来基于不同 OFSs 的单参数和多参数 TSP 传感和测量的最新 TSP 传感器。此外，从实用的角度出发，还讨论了保护光纤和维持 OFSs 在海水中正常运行的封装方法，以及 OFS 的响应时间。最后，我们讨论了 OFSs 在海洋环境中的应用前景和挑战，并为未来的工作提供了一些线索。
