摘　　要：本文在40Gb/s非等幅OTDM传输系统的基础上,围绕超短脉冲的产生、信号复用、色散补偿和时钟提取技术进行优化设计。介绍了采用掺铒光纤放大器获得超短脉冲;利用方程差微调法获得光时分复用信号和易于实现动态色散补偿的啁啾光纤光栅实现色散补偿,以及通过适于高速光时分复用系统的光时钟提取技术提取时钟脉冲等内容。最后给出了低抖动、低误码率、性能稳定的传输系统。An optimized design centering on the key technology, system characteristics and basic structure of 40Gb/s optical time division multiplexing system is analyzed in this paper. It introduces the process of getting ultra-short pulse using a gain switched quantum well DFB laster as signal pulse source, the method of obtaining OTDM signal and extracting short pulse through the technique of extracting light-pulse which apply to high-speed OTDM system. Consider the dispersion and the clock extraction, DCF、CDPF、EAM and PLL are available chooses. Compared with general OTDM transmission system, this novel design will apply a high reliability OTDM system.
