伴随着国家“宽带中国”战略及实施方案的颁布,我国宽带基础设施将进入快速健康发展的轨道。另外,高速互联网、互动电视、3D高清视频、云计算、云存储、物联网等宽带应用的不断涌现,促使传输网络从骨干到城域网络带宽需求成倍增长。在网络高速发展的时代,100G WDM/OTN大容量传输网络建设将是广电缓解带宽压力的最佳手段。
With the promulgation of the national “Broadband China” strategy and implementation plan, China’s broadband infrastructure will enter the track of rapid and healthy development. In addition, high-speed Internet, interactive television, 3D high-definition video, cloud computing, cloud storage, Internet of Things and other broadband applications continue to emerge, prompting the transmission network from backbone to metro network bandwidth demand doubled. In the era of rapid development of the network, the construction of 100G WDM / OTN high-capacity transmission network will be the best means for broadcasting to alleviate the pressure of bandwidth.
