Instead of sunbeams, today's light-wave communication systems use laser light ricocheting through tiny glass fibers. 今天的光波通信系统利用的不是日光束,而是通过微细玻璃纤维掠射的激光。
It is pointed out that the coherent light-wave systems for space optical communication links are better between the GEO satellites, since the high receiving sensitivity is very important in this case. 指出对于同步卫星间这种超长距离的光通信系统,高的接收灵敏度是至关重要的,因而相干光通信技术更有优势;
