摘要
针对广电光纤网络信号传输特性易受广域、远距等因素影响,无法建立稳定传输通道等问题,提出一种基于光传送网(Optical Transport Network,OTN)技术的网络模型,利用密集型光波复用(Dense Wavelength Division Multiplexing,DWDM)设备将多类广电信号进行转换汇聚,有效提升大范围跨域信号的传输效率。从频谱监测、功耗检测等不同角度论证波分复用(Wavelength Division Multiplexing,WDM)层的OTN技术特性,并通过算法仿真和数据分析验证网络模型的有效性。
In view of the problem that the signal transmission characteristics of radio and television optical fiber network are easily affected by factors such as wide area and long distance,and can not establish stable transmission channels,a new network model based on Optical Transport Network(OTN)technology has been proposed in this paper,in which Dense Wavelength Division Multiplexing(DWDM)equipment had been utilized to convert and gather multiple types of radio and television signals,effectively improving the efficiency of large-area cross-domain signal transmission.The OTN technical characteristics of Wavelength Division Multiplexing(WDM)layer are demonstrated from different perspectives such as spectrum monitoring and power consumption detecotin,and the effectiveness of the network model is verified by algorithm simulation and data analysis.
