超高速超大容量超长距离(3U)光传输作为一种新型光通信模式,推动了下一代互联网和宽带移动通信网的发展和技术进步,已成为国际高科技知识产权竞争的焦点和制高点。从3U光传输研究的背景与意义出发,给出了3U光传输的3个科学问题,并介绍了3U光传输的体系架构、研究的基础理论与关键技术,最后介绍了3U光传输的实验验证平台和在该平台上完成的重要实验以及产学研结合创新成果的产业化应用范例。
Ultra-high-speed, ultra-large-capacity and ultra-long-haul (3U) optical transmission as a new mode ofcommunication can greatly promote the next generation of optical internet and broadband mobile communicationnetwork development and technological progress, therefore 3U has become the focus of international high-techintellectual property and competition ground. Starting from the background and significance of 3U research, the threescientific problems in 3U were given, and the architecture, basic theory and key technology of 3U opticaltransmission were introduced. Finally, the verification platform was introduced together with the importantexperiments completed on the platform, as well as the industrial application of the innovative achievements.
