- The disadvantage of FSO over fiber is that laser power attenuation through the atmosphere is variable and difficult to predict, for it is weather dependent. 由于信道和天气相关 ,因此 ,在大气中光功率的损耗是不确定的 ,并且难以预测。
- Some effects on optical power attenuation properties were analyzed, such as the polished length, the thickness of the remained cladding of side-polished fiber, and the refractive index (RI) of polymer covered on the polished area. 同时计算了侧边抛磨光纤在不同的结构参数及聚合物折射率参数下的光功率传输特性，分析了光纤抛磨长度、剩余包层厚度及抛磨区涂覆的聚合物折射率这三个参数对抛磨光纤器件的光功率传输特性的影响。 研究表明，当抛磨长度小于9mm时，光功率衰减随剩余包层厚度的增大单调递减；
