激光大气通信系统是一种机动性好、操作简便、轻巧可靠、适用于4km以内的多路双向传输通信设备,可用作不便敷设光缆的建筑物之间正常通信,或者用于突发事态紧急救助时的通信,增强了通信网的机动灵活性和隐蔽性以及抗毁能力。随着通信业务的发展,4km的距离远远不能满足通信的需要,目前,迫切需要扩大传输容量、延长传输距离。如何把通信距离延长到8km以上,系统的全年通过率大于93％?随着光纤技
The laser atmospheric communication system is a kind of multi-way bidirectional transmission communication equipment with good maneuverability, simple operation, lightness and reliability and suitable for applications within 4km. It can be used as normal communication between buildings which are inconvenient for laying optical fiber cables or used for emergencies Communication at the time of bailouts has enhanced mobility and covertness of communication networks as well as anti-destruction capabilities. With the development of communication services, the distance of 4km can not meet the needs of communication. At present, there is an urgent need to expand the transmission capacity and extend the transmission distance. How to extend the communication distance to more than 8km, the annual pass rate of the system is more than 93%? With the optical fiber technology
