摘要
伴随现代科学技术水平的提高和网络通信技术的发展,网络传输方式愈发受到人们的欢迎和喜爱,信息时代由此产生。高速发展的信息社会要求通信网络具备提供多样化电信业务的能力,一定程度上增加了电信网络交换、处理和传输信息的总任务量,使得通信网络逐渐朝着综合化、数字化、信息化的方向发展。SDH作为一种现代化的信息传输系统,以其为切入点,借助相关工程,对长途光缆传输的工程设计工作展开细致研究与分析,以期能够为推动SDH传输系统的发展奠定良好的基础。
Along with the development of modern science and technology and and of network communication technology, the network transmission mode attracts even more attention from people, and information age arises at the historic moment. The rapid development of information society requies that the communication network must have the ability to provide various telecommunication services, and this would, to a certain extent, increases the total task of telecommunication network in exchange, transmission and processing of information, and make the communication network gradually move towards integration, digitalization and informatization. SDH serves as a modern information transmission system, to it as the breakthrough point and with the help of related engineering, calculation work on engineering design of long distance optical cable transmission is studied and analyzed in detail, thus to lay a good foundation for the development of SDH transmission System.
