| 摘 要： | 介绍了PWM传输系统原理、特点及设计方法。提出了一种基于PWM的新型移动通信光纤及多路中继传输系统。该系统可以排除现有模拟光纤中传输系统中的非线性和噪声干扰，而要求的传输码率又比一般数字系统低近10倍，成本比相同传距的模拟光纤中继器低十多倍。

| Abstract: | The principles, features and design methods of PWM transmission system are described. A new optical data link based on PWM for mobile communication is presented. The PWM system can take off the nonlinearity and interference from noise; its bandwidth overhead decrease by about 10 times as compared with digital system; its cost decreases by over 10 times as compared with analog system at same link distance. |
