摘　　要：在研究各种高速光纤通信系统色散补偿方案的基础上,提出在80Gb/s的WDM系统中根据不同载波频率的分波长色散补偿与对称补偿相结合的色散补偿方案。结果表明,分波长补偿与对称补偿相结合的色散补偿方案相比传统的后色散补偿方案可以有效提升光纤通信系统的Q值。将分波长补偿与对称补偿相结合的色散补偿方案分别应用到基于RZ(归零)码和高斯脉冲幅值键控两种调制格式的8通道WDM系统中,并分析了补偿效果。Based on the study of various dispersion compensation schemes for high-speed optical fiber communication systems,a dispersion compensation scheme was proposed in 80 Gb/s WDM system,which combined wavelength-division dispersion compensation and symmetric compensation according to different carrier frequencies.The results show that compared with the traditional post-dispersion compensation scheme,the dispersion compensation scheme with the combination of wavelength compensation and symmetrical compensation can effectively improve the Q value of the optical fiber communication system.The dispersion composition scheme combined the wavelength division compensation and symmetric compensation is applied to the eight-channel WDM system,which is based on the two modulation formats of RZ(return to zero)and Gaussian pulse amplitude keying,and the compensation effect is also analyzed.
