Abstract: more than 80% of the world, information is transmitted through optical fibers. Optical munication from research to application, developed rapidly: the continuous upgrading of technology, communications relay transmission rate and increasing the product of the distance range of applications has expanded. Optical munication is the main transfer of modern means work. Fiber has been widely used in the world, has e the basis works. Optical fiber technology must support the most important means of information flow.
Key words: optical munication, increase the transmission rate, increase the transmission distance, communication capacity, the development trend of optical switches, submarine works, the development of synchronous work

2 发展史
1966 年,英籍华裔学者高锟()和霍克哈姆()发表了关于传输介质新概念的论文,指出了利用光纤进行信息传输的可能性和技术途径,奠定了现代光通信—光纤通信的基础。自此以来,光纤通信从研究到应用,发
