随着社会信息化进程不断推进,业务容量以超摩尔定律的速率发展。未来4~5年全网流量的年增长率会高达60~70%,预计2020年全球流量将是2010年的33倍,以数据、视频业务为主的移动互联网带宽更是将呈现“10年增长1000倍”的发展态势。当前的10G和40G光传输系统无法满足高速增长的传输容量需求,100G应运而生。中国电信科技委主任韦乐平指出,按照目前的流量发展趋势,2017年中国电信最大截面传输带宽约为38T,骨干网的承载将需要5个
With the continuous progress of social information, business capacity at the rate of over-Moore’s law. The next four to five years the entire network traffic growth rate will be as high as 60 to 70%, the global traffic in 2020 is expected to be 33 times in 2010, the data and video services-based mobile Internet bandwidth is to show “10 Annual increase of 1000 times ”development trend. The current 10G and 40G optical transmission systems can not meet the high-speed transmission capacity needs, 100G came into being. Wei Leping, director of China Telecom Science and Technology Commission pointed out that according to the current trend of traffic development, the maximum cross-section transmission bandwidth of China Telecom will be about 38T in 2017 and the backbone network will bear five
