摘　　要：首先说明通信业务种类的发展和数据通信业务量急剧增长的情况。再简述光纤线路扩大容量和延长距离所需的波分多路与光纤放大器技术以及光纤类型和特性的相应选择。接着，估测通信网体制将从传统电话网进化为以分组为基的核心网。The paper begins with explaining the development of various kinds of communication services and the explosive growth of IP data traffic.Then,it briefly describes the WDM and EDFA technologies used for expanding the capacity and extending the distance of optical fiber transmission line, and the proper choice of types and characteristics of optical fiber.Finally,it predicts the evolution of national communication network from traditional telephone network to the IP packet based network,and the evolution of electrical communication network to optical network in the early years of next century.
