摘　　要：本文介绍了利用非等幅原理进行帧时钟分量提取的原理 ;阐述了 40Gbit/s光时分复用 (OTDM)系统中利用电时钟提取技术实现 10GHz帧时钟的理论模型和实验框图 ;分析了OTDM光信号参数和时钟提取单元参数对系统的影响 ,并给出了理论分析结果 ;分析了应用于实际中的时钟提取单元的实现过程和实验结果 ;并对理论结果和实验结果进行了分析和比较 .A practical 10GHz frame-clock extraction technology based on unequal coding scheme and high Q value filter is introduced and analyzed. We illustrate its basic principle and propose the theoretical models to simulate the effects of parameters of OTDM (Optical Time Division Multiplexing) signals and high Q value filter. Also, we employ this technology in our practical 40 Gbit/s OTDM system, and acquire a series of curves and results related to this unit. Finally, the theoretical and experimental results are compared and discussed.
