Features: In recent years, optical transmission systems have continuously made progress in two directions: increasing transmission capacity and extending transmission distance. Each significant improvement in transmission capacity and distance has been achieved through the adoption of new technologies and the resolution of key issues, while also giving rise to new limiting factors. This book systematically introduces various key new technologies developed by researchers on the path to increasing transmission capacity and extending non-repeatered distance, comprising a total of 9 chapters. Chapter 1 introduces the development trend of high-speed, ultra-long-distance transmission in optical communication systems, the technical challenges faced by high-speed, ultra-long-distance transmission systems, the key technologies used, and the application advantages of high-speed, ultra-long-distance optical transmission systems. Chapter 2 covers multiplexing technologies for high-capacity transmission, technical specifications of high-speed, ultra-long-distance optical transmission systems, and new wavelength division multiplexing (WDM) technology. The remaining chapters systematically discuss the basic principles and application methods of various key technologies in high-speed, ultra-long-distance optical transmission systems, including new fiber technologies, dispersion compensation technology, Raman amplification technology, forward error correction (FEC) technology, new encoding and modulation technologies, and high-speed optical soliton transmission technology. The final chapter takes the "Jinan-Qingdao-Dalian" trans-oceanic long-distance transmission system and the "Xining-Golmud-Urumqi" land-based long-distance transmission system as examples to introduce the technical advantages, system design methods, and application models of high-speed, ultra-long-distance transmission systems. This book serves as a reference for professionals engaged in optical communication technology research, optical transmission system development, production, engineering maintenance, and operation management. It can also be used as a training textbook for engineering management personnel, as well as a reference for university professors and students majoring in optical communication.
