We propose a novel fiber-based free-space optical (FSO) coherent receiver for inter-satellite communication. The receiver takes advantage of established fiber-optic components and utilizes the fine-pointing subsystem installed in FSO terminals to minimize the influence of satellite platform vibrations. The received beam is coupled to a single-mode fiber, and the coupling efficiency of the system is investigated both analytically and experimentally. A receiving sensitivity of -38 dBm is obtained at the forward error correction limit with a transmission rate of 22.4 Gbit/s. The proposed receiver is shown to be a promising component for inter-satellite optical communication.
我们提出了一种用于卫星间通信的新型基于光纤的自由空间光（FSO）相干接收机。该接收机利用了成熟的光纤组件，并利用安装在FSO终端中的精确定向子系统来最小化卫星平台振动的影响。接收光束耦合到单模光纤，并通过分析和实验研究了系统的耦合效率。在22.4 Gbit/s的传输速率下，在前向纠错极限处获得了-38 dBm的接收灵敏度。所提出的接收机被证明是卫星间光通信的一个有前途的组件。
