摘要: 介绍了空间光通信系统的基本结构,并根据长距离星间链接的特点,提出一种采用EDFA技术的光发射机和光接收机模型,以实现大功率激光输出和接收机的高灵敏度。提出一个622 Mb/s系统的功率预算方案,通过分析,证明该方案是能够实现的。Abstract: In this paper,the typical architecture of free-space optical communication systems is introduced.In order to generate high laser output power and acquire high receiver sensitivity,a model of optical transmitter and receiver is presented,which is based on long-range inter-satellite links.The power budget of 622 Mb/s system is put forward.The analysis shows that the model is easily achieved.
