摘　　要：文章简要介绍了第五代移动通信技术(5G)前传网络技术架构,对中国电信和中国联通共建共享建网模式下5G前传需求进行了分析,并给出了5G前传承载实施方案;同时,结合中国电信与中国联通5G共建共享模式下的工程建设经验,给出了5G前传网络建设规划、工程设计及施工方案建议。基于无源波分复用技术,可以有效减少光纤资源消耗,降低建网成本,对于多快好省地实现5G前传网络覆盖具有较好的指导意义。This paper briefly introduces the technical architecture of the 5th Generation Mobile Communication(5G)forward transmission network,analyzes the 5G forward transmission requirement under the 5G co-construction of China Telecom and China Unicom,and gives the implementation scheme of 5G forward transmission.Combined with the 5G co-construction engineering practices of China Telecom and China Unicom,the article gives 5G fronthaul network construction planning,engineering design and construction plan suggestions.Based on the passive wavelength division multiplexing technology,the operator can effectively reduce the consumption of optical fiber resources and reduce the cost of network construction,which provides guidance on how to achieve 5G fronthaul network coverage quickly and economically.
