Research On The Planning Of Passive Optical Networks In "Safe City"

With the rapid development of Chinese economy,our country,s construction of "safe city" is getting attention,and the network capacity,speed,service and safety requirements are also higher and higher.Traditional access technologies such as DSL,Ethernet,coaxial cable etc,has been unable to meet the needs of business development,high bandwidth and long distance fiber access technology has gradually become the mainstream of "safe city" access network.Passive Optical Network(PON)becone the main access technology because it has a lot of features such as low-cost,high-bandwidth,long-distance and fully passive.So the study of the optical access network in the article,fitting for the development of the "safe city" industry.As complex environment,immense scale,cost-sensitive and other factors,there are a lot of problems in the existing network,such as waste of resources,inefficient use and so on.Therefore,it is important to study PON planning in "safe city".In this article,we conducts intensive study on PON planning and mainly includes the following points:1?Planning and design for the deploylent of equipment and COIn depth study of research for CO region of the mesh,business development and forecasting methods,CO regional planning process,OLT deployment strategy and ONU planning.By such research,this program makes the planning more reasonable and convenient.2?ODN planning and designStudied the optical access network design,splitter placed to do the plaxning,formed the feasible ODN plan.From the above research,a good solution to the problems of network planning in "safe city".At last,all of which have been carried out through a project,the results prove its feasibility.
