摘　　要：随着宽带中国战略的推进及IPTV业务的发展,WDM技术正在下沉到县乡层面。县乡业务的承载方式需综合考虑县乡光缆环长、剩余纤芯数以及业务量。建设县乡波分时,节点应在基础架构定义的乡镇综合业务接入点范围内选择;乡镇节点应选择紧凑型波分设备;采用点对点配置,各乡镇节点独享波道,中间节点FOADM直通。With the promotion of Broadband China strategy and the development of IPTV business,WDM technology is sinking to the town layer. The carrying mode of county and town business needs to consider optical cable loop length,remaining optic core number and traffic. The node needs to be selected from town integrated service access points. The town node need select compacted WDM,point-to-point configuration to provide private wave channel for town,middle node is connected to FOADM.
