摘要
近年来我国以FTTH和4G LTE为代表的固定和移动宽带业务迅猛发展,驱动我国网络基础设施取得跨越式发展,在高速大容量光纤传输技术的发展和应用方面更是领先全球。目前N×100 Gbit/s波分复用(WDM)传输技术已经普及,正在从骨干网向城域网延伸;N×400 Gbit/s WDM传输技术的部署也指日可待;介绍了N×400 Gbit/s WDM传输技术方案和标准制定情况,并对该技术的应用前景和后续发展进行展望。
China＇s FTTH fixed broadband and 4 G LTE mobile broadband services develop rapidly in recent years. China begins to lead the development of technology and application of high speed broadband optical fiber transmission systems. N×100 Gbit/s WDM systems have been widely deployed in China,from backbone to metro networks.The deployment of N×400 Gbit/s WDM system is also on horizon. It introduces the key technology solutions and standardizations of 400 Gbit/s WDM system,and then discusses its deployment scenarios and further development.
