摘要
自由空间光通信可以提供快捷、经济的宽带访问,然而易受天气条件和传输距离限制。文章讨论了如何设计混合FSO/RF系统的链路,使之两种系统相互辅助,提高系统的有效性。链路恢复技术中的动态负载交换算法实现了FSO和RF间的负载交换,确保在不同传输损耗下的服务质量。
Free Space Optics (FSO) can provide inexpensive, rapidly deployable broadband access. However, it is also limited by the weather conditions and transmission distance easily. The link of hybrid FSO/RF system which can backup each other and increase the availability of the system is discussed in the paper. Link restoration technique such as Dynamic Load Switching (DLS) is deployed for ensuring the load switching between FSO and RF,and maintain the quality and availability of the link under different transmission loss.
