摘要

自由空间光链路通过自由空间提供高数据速率传输。最大的缺点是真实大气对链接可用性的影响很大。这篇文章展示了在实验双波长光链路上4年的测量结果(1.2009-12.2012)。米列索夫卡山上的测量地点非常具体。这种联系经常出现在到达山顶的低云中间。因此，我们可以测量由云引起的衰减。我们的结果表明，与以能见度为参数的理论模型相比，衰减更高。另一方面，测量的降雨衰减与法国Carbonneau确定的模式一致。

Long-term analysis of atmospheric effects on free space optical links

Free space optical links provide a high data rate transmission through free space. The biggest disadvantage is a high impact of real atmosphere on availability of the links. This contribution shows results from the 4 years measurement (1.2009-12.2012) on experimental dual-wavelength optical link. The measurement site on the Milesovka Mt. is very specific. The link is very often in the middle of low cloudiness reaching the top of the mountain. Thanks to that we can measure the attenuation caused by the clouds. Our results show that the attenuation is higher comparing to the theoretical model that uses visibility as a parameter. On the other hand the measured rain attenuation is in agreement with the model determined by Carbonneau in France.
