摘　　要：C-RAN是5G基站的主要部署方式,如何低成本、高效率地解决DU-AAU之间的前传承载需求是实现5G基站C-RAN部署的关键问题之一,在详细论述5G前传业务需求的基础上,分析比较了无源CWDM、有源OTN、Open-WDM、PAB-WDM等各类前传承载技术方案,并给出应用建议,为规范前传承载方案、提高5G网络建设效能提供了参考。C-RAN is the main deployment mode of 5G base stations.How to solve the pre-transmission bearer requirements between DU and AAU with low cost and high efficiency is one of the key issues for implementing C-RAN deployment of 5G base stations.Based on the detailed discuss for pre-transmission business requirements,various pre-transmission bearer technologies including passive CWDM,active OTN,Open-WDM,PAB-WDM are analyzed and compared,and the application recommendations are put forward,which provides a reference for standardizing the pre-transmission scheme and improving the efficiency of 5G network construction.

关 键 词：C-RAN 前传承载 WDM
