In order to provide a comprehensive, systematic understanding of modern optical fiber communication systems to the characteristics of the principle of key technology and its applications, and optical fiber communications in the 21st century, the development trend, I wrote a paper election. This paper seeks to easy-to-digest, step by step, the basic concepts and basic principles of accuracy clear, concise proof, to avoid the complicated reasoning, focused on the conclusion will focus on basic principles and practical application of organic integration, with special attention to the image, intuitive map Standard form to cope with the narrative text, people can seize the key technology and comprehensive understanding of this content.  This paper describes the optical fiber communication and application of the basic characteristics, mainly on SDH technology and application of the principle, and a brief introduction of several modern optical fiber communication technology and communication technology tren
