摘　　要：全光3R再生(再定时、再整形、再放大)是全光通信网的核心技术之一,其中时钟恢复是再定时和再整形的基础。时钟恢复输出的时钟脉冲须具有高速、低相位噪声、高灵敏度、偏振不敏感和稳定的特点。首先介绍了3R再生的研究背景和研究现状,讨论了全光3R再生的基本原理,重点分析了3R再生中所使用的几种时钟恢复方法,并对其进行了比较。All-optical 3R regeneration （Re-timing, Re-shaping, Re-amplification） is one of the key techniques needed for the all-optical networks, and clock recovery is the basis of re-timing and re-shaping. The output clock pulse of clock recovery should have the features of high speed, low phase noise, high sensitivity, no polarization sensitivity, and stability. In the thesis the research background and the current research of 3R regeneration are introduced. Then the basic principle of all-optical 3R regeneration is presented. And several methods of clock recovery are analyzed and compared.
