摘　　要：针对业界聚焦的5G前传光纤直驱Duplex、BiDi方案和低成本CWDM、LWDM、MWDM、DWDM方案,首先对不同类别区域的光缆管道建设需求和规模应用时的综合成本建立了数学计算模型,采用定量的方法对其进行了全面预测。然后从工程建设可行性和网络建设成本两方面对5G前传各技术方案规模应用的可行性进行了论证分析。最后给出了5G前传网络演进和各技术方案的应用策略建议,供电信运营商评估和制定网络建设技术方案时参考。In view of the 5G fronthaul optical fiber direct connection Duplex and BiDi schemes and low-cost CWDM,LWDM,MWDM and DWDM schemes focused by the industry,it firstly establishes the mathematical model for the construction demand of optical cable and pipeline in different regions and the construction cost when they are applied on a large scale,and makes a comprehensive prediction with quantitative method. Secendly,it demonstrates and analyzes the feasibility of the scale application of various technical schemes of 5G fronthaul from two aspects of engineering construction feasibility and network construction cost. Finally,it gives the evolution strategy of 5G fronthaul transmission network and the suggestions on application strategy of each technical scheme,which can be used as a reference for telecom operators to evaluate and formulate the technical schemes of network construction.
