信息高速公路与高速光纤通信网

Information Superhighway and High-speed Fiber-optic Communication Network

介绍了信息高速公路中有关高速通信网的几个新名词；阐述了高速通信对传输与交换的要求，光纤、光子器件与光波传输系统的发展，同步光纤传输网与异步转移模式的应用，以及各种不同用途通信网的互连与组合；并展望通信网的跨世纪发展前景．

The paper firstly introduces the new terminology used in the high bit--rate communication network related with 'information superhighwayp. Then, it des.Pribes the transmission and switching requirements of the high bit--rate communications. the development of opticsl fiber, opto--electronic devices, and lightwa.ve transmission system, the application ofsynchronous transmission network and asynchronoU$transfer aide, as well as the intercon.nection and collaboration of varioUs,kinds of comngqnication networks. Finally, the paperpredicts the future prospects if communicating networks in the neXt century.
