摘　　要：所谓"三超",即超高速、超大容量、超长距离,这三个主题是光通信乃至整个通信业一直追求的目标。三超光传输作为一种推动下一代互联网与宽带移动通信网发展和技术进步的新型光通信模式,已成为国际高科技知识产权竞争的焦点和制高点。文章介绍了三超光传输中的科学问题、关键技术,以及国内在这方面取得的重要成果。Ultra-high-speed,ultra-large-capacity and ultra-long-haul （3U）are the forever pursuit of optical communication or e-ven the whole communication industry.As a new mode of communication 3U transmission can greatly promote the next genera-tion of optical internet and broadband mobile communication network development and technological progress,therefore 3U has become the focus of international high-tech intellectual property and competition ground.This paper introduces the scientific problems,key technologies,and important achievements that have been made in 3U transmission.

关 键 词：超高速 超大容量 超长距离 光传输 高谱效率 光编码 光调制
