摘　　要：DWDM(密集波分系统)作为目前大容量传输光网络,以其节省光缆资源和高速率多系统传送的特点,逐步被人们所认识和广泛应用。本文对DWDM系统的线路光功率衰减特点、倒换触发告警、倒换时间以及数据路由器HLOD OFF TIME参数设置等4个方面进行深入研究,了解DWDM系统倒换机制与数据路由器参数设置的协调工作的特性,寻找DWDM系统承载数据GE业务的最佳参数设置,从而我们深入了解DWDM网的工作原理、保护和恢复机理等。通过分析济南联通现有DWDM网络所承载的数据业务类型、服务等级、设备现状以及相关实验测试,提出了DWDM系统和数据网路由器HLOD OFF TIME参数最佳的配置,并针对现有业务承载修改参数后的测试结果,提出最终研究结论。DWDM （Dense WDM） as a high-capacity transmission optical network, its saving cable resources and high-speed multi-system transfer characteristics gradually been recognized and widely used. DWDM line optical power attenuation characteristics, switching trigger alarms, switching time and data routers HLOD OFF TIME setting four sides of an in-depth study to understand the characteristics of the switching mechanism of DWDM systems with data router parameters set coordination, looking for DWDM systems carry data GE business best parameter settings, thus our understanding of the working principle of the DWDM network, protection and recovery mechanism. By analyzing the Jinan Unicom＇s existing DWDM networks carrying data traffic type, grade of service, equipment status, and experimental testing of DWDM systems and data networks is HLOD OFF TIME parameter configuration, and modify parameters for existing businesses carrying after the test results, presented the final conclusions.
