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６２２Ｍｂ／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。
In this paper,the typical architecture of freespace 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 longrange intersatellite links.The power budget of 622 Mb/s system is put forward.The analysis shows that the model is easily achieved.
