摘要
光纤通信作为二战以来最有意义的四大发明之一,奠定了网络信息传输的基石,承载了全球90%以上数据流量,但预计其未来20年将遭遇"传输容量危机".本文围绕超高速率、超大容量、超长距离、超宽灵活、超强智能(ultra-high speed, ultra-large capacity, ultra-long distance, ultra-wideband flexibility, and ultra-powerful intelligence, 5U)这5个光纤通信的发展维度开展研究,在回顾了其50多年发展历程的基础上,对近10年来所取得的一系列最新进展进行了全面综述,并就未来10年甚至20年的演进趋势做出展望.
As one of the four most significant inventions since World War II, optical fiber communication has provided a foundation for the development of the information society, carrying more than 90% of the global data traffic. However, it is expected that it will encounter a "capacity crisis" in the next two decades. This paper focuses on the five development dimensions of optical fiber communications: ultra-high speed, ultra-large capacity, ultra-long distance, ultra-wideband flexibility, and ultra-powerful intelligence(5U). Based on a review of its development over the past 50 years, the paper provides a comprehensive review of the latest progress achieved in the past decade and presents a bold outlook on the evolutionary trends in the next decade or even two. This review hopes to provide a reference for researchers in related fields.
