摘要
为了改善长距离、高速率波分复用(WDM)光纤传输系统中色散补偿光纤(DCF)的色散补偿效果,提出针对不同载波频率的分波长色散补偿方法。使用Optisystem软件,采用分波长色散补偿方法搭建WDM系统并和传统后置色散补偿方法进行比较。针对速率为80Gb/s的高斯脉冲幅度调制WDM光纤传输系统的传输性能要求,进行色散补偿光纤的分波长色散补偿方法和后色散补偿方法的仿真实验。实验结果表明:分波长色散补偿方法能有效提高WDM系统的Q值。
In order to improve the dispersion compensation effect of dispersion compensation fiber(DCF) in long-distance and high-speed wavelength division multiplexing(WDM) optical fiber transmission system, a wavelength-division dispersion compensation method for different carrier frequencies is proposed. Using Optisystem software, the WDM system is constructed by wavelength-division dispersion compensation method and comparisons with traditional post-dispersion compensation methods. In view of the transmission performance requirement of Gauss pulse amplitude modulation WDM optical communication system with a rate of 80 Gb/s, simulation of wavelength division dispersion compensation and post dispersion compensation is implemented. The results show that the proposed dispersion compensation scheme gets better system performance in Q-factor.
