摘要
高清视频和高速数据业务的迅速发展对网络的带宽需求越来越高。一些领先的运营商已经开始规模建设单波道40Gbit/s的DWDM网络,还有运营商开始关注单波道100Gbit/s的超高速传送系统。目前全球有三个标准组织ITU-T、IEEE和OIF正在积极制定100Gbit/s的相关标准,并有了较详细的计划。未来100Gbit/s系统将首先在大容量核心路由器之间的互联,以及长途和地区间的传送网两个场景使用。但是100G从设备成熟度、标准以及运营管理维护等方面都需要不断完善,真正大规模商用还需几年。
With the rapid development of HD video and high-speed data services, demand for band- width becomes higher. Some leading communication operators becomes large-scale construction of sin- gle channel 40 Gbit/s DWDM, other enterprises pay more attention on 100Gbit/s ultra-high speed transmission system. Currently, the standards of 100Gbit/s develop by ITU-T, IEEE and OIF. 100G/ bits transmission system will using for intereonnection in high capability core router and long distance or interregional transmission network in the future. Because of the maturity, standard and management issues, large-scale commercial for 100 Gbit/s will takes several years.
