摘　　要：针对5G前传网络对光纤资源需求的爆发式增长,提出了一种低成本WDM PON架构和系统,采用WDM和单纤双向技术可节省78%以上的主干和配线光纤资源。同时,低成本WDM PON系统还具备光模块类型少、可维可管、可靠性高等优点。对低成本WDM PON可调光模块和顶调制等关键技术进行了研究,并对低成本WDM PON现网示范应用进行了分析和探讨。In response to the explosive increase in the demand for optical fiber resources in 5G fronthaul networks,this paper proposes a low-cost WDM PON architecture and system that uses WDM and single-fiber bidirectional technologies to save more than 78%of the backbone and distribution optical fiber resources.In addition,the system has the advantages of few types of optical modules,maintainability and manageability,and high reliability.Research on key technologies such as low-cost tunable module and envelope modulation has been carried out,and a field demonstration of low-cost WDM PON system has been completed.
