光纤通信用可调谐色散补偿器的研究进展
Progress in tunable dispersion compensators for fiber-optic communications
摘要
40 Gbit/s 密集波分复用(DWDM)系统对色散要求较高，传统的色散补偿只能粗略补偿系统色散，对于残余色散和由环境变化导致的色散变化等则无能为力。可调谐色散补偿器(TDC)可根据系统色散的变化自动调整色散补偿量，从而达到理想的补偿效果。文章介绍了几种动态色散补偿的实现方案，并对其进行了一定的比较和分析。
Abstract
Conventional dispersion compensators cannot satisfy the requirement of 40 Gbit/s DWDM systems for accurate control of the dispersion and neither can they do anything about the remnant dispersion or the dispersion variations caused by circumstances. A Tunable Dispersion Compensator (TDC) can adjust the dispersion compensations automatically in line with the system dispersion variations, achieving the ideal compensation effects. In this paper, several dynamic dispersion compensation schemes are presented, compared and analyzed.
