我国光纤通信系统演进的阶段与展望

The periods of optical fiber communication system development in China

光纤通信商用化以后,由于市场需求和技术进步的推动,光纤通信系统依次经历了PDH光传输时代、SDH光传送网时代、大容量WDM传输时代等发展时代。考察了我国光纤通信系统技术的演进与发展,并且指出今后的光纤通信系统将向超高速大容量,分组化,智能化,全光网方向发展。

after the application of optical telecommunication,with the market demand and technological progress,the optical fiber communication systems technology has developed several periods in china ： the stage of PDH fiber optical transmission,the stage of SDH optical transport network,the stage of high-capacity WDM transmission.With the evolution of optical fiber communication system,the trend of optical fiber communication systems is followed： high-speed,high-capacity,packet,intelligent,all-optical network.
