Research On Optical Access Network Optimization And Applications For 5G Bearer Networks

The fifth-generation communication technology(5G)is committed to building an ecosystem of information and communication,which is one of the hottest topics in the industry.Due to 5G typical characteristics such as ultra-high data-rate,ultra-high frequency band,ultra-high density,ultra-low delay,etc,there is an urgent increasing requirement for optical bearer networks.With the arrival of5 G and completion of household customer optical network coverage,the entire telecom vendor's optical fiber networks will face structural optimization and adjustment.The planning and deployment of the integrated service access area can meet various access requirements including base stations,leased lines,and home broadband,etc.It is widely accepted as one of the best solutions for the current and future explosive demand of optical cables.This thesis presents research on integrated service access area planning and its application based on actual projects in Yichun Telecom local network.This thesis gives a brief introduction of 5G development and its key technologies firstly.Secondly,the 5G implementation requirements for bearer networks are discussed comprehensively.Based on the analysis of existing problems and access requirements of Yichun Telecom's ODN network,the integrated service access area planning principles,objectives and implementation procedures are provided,respectively.Some key such as the division of the integrated service area,service station site setting,optical node deployment,and the trunk cable routing are analyzed and proposed.Finally,this thesis presents a specific planning and design of Yichun Telecom integrated service access network which is verified by actual project implementation.
