For example,the maintenance of multiple networks can require additional staff.often,this staff must be trained on multiple vendor technologies,sometimes requiring parallel groups specializing in each （72） hence,additional maintenance procedures must be maintained and administrative records are （73） the duplication of trasport facilities to carry （74） network traffic is an inefficient use of resources and,not surprisingly,more technologies installed in a central office mean the necessity for more physical space,and an increase in power connections and power consumption.migration of these （75） network elements to IP-based DCns is alogical strategy

例如，维护多个网络需要增加工作人员。通常这些人员必须培训，以便熟悉多种制造商技术，同时还需要熟悉不同平台的许多工作小组。因此，额外增加的维护过程使得各种管理记录激增。承载着不同网络通信的多种传输设施造成了资源的无效使用。很自然的推论就是，更多的技术装置配备在交换局中意味着需要更大的物理空间，增加了动力设备和电源消耗。这些遗产网络元素逐步迁移到基于IP的DCN是符合逻辑的策略。

In this paper, firstly we researched the relationships of the communicating distanceand the channel characteristic, the effect of the multiple scattering to the laserpropagation, the requirement of the laser communication to the ATP system and theway to determine the angular dispersion and receive field of view. It is proved that inlight haze weather, letting the input and output laser\'s wavelength are diferrent witheach other, after passing by the filter, it can avoid backward scattering effectually andfor the communication within 15km, the influence of the multiple scattering inatmosphere can be ignored.
