摘　　要：介绍了逐渐受到更多关注的高速光纤通信系统的电色散补偿(EDC)技术。我们将研究对象放在了采用啁啾DFB激光器、直接调制方式的2.5Gb/s高速光纤通信系统,通过仿真得到:啁啾系数为2的DFB激光器传输400km后经过8抽头判决反馈均衡器处理可有效地消除色散导致的码间干扰。Electronic dispersion compensation is a valuable technology for high-speed optical communications system. We research 2.5Gb/s system based on chatter-DFB laser and direct modulation. Simulation result indicates that 8 tapped decision feedback equalizer can eliminate ISI of chatter-DFB after being transmitted 400km.

关 键 词：电色散补偿 码间干扰 自适应均衡
