摘　　要：提出了一个以色散补偿光纤及光纤光栅相结合的分波色散补偿方案,对已经建立的4×10Gb/s波分复用系统的各路信号进行精确地色散及色散斜率补偿仿真研究,得出4路光信号的各自最佳输入光功率及色散补偿光纤的长度以及相应的最高Q参数。结果表明,该方案对当前体系的色散及色散斜率补偿效果良好。A project of dispersion compensating for respective wavelength which used of dispersion compen- sating fiber and fiber Bragg grating has been proposed, and it has been used in a simulated 4x 10Gbit/s wave- length division multiplexing system to compensate dispersion and dispersion slope of respective optical signal accurately, the effect of dispersion compensation is fine. The optimal input power of respective channel and the DCF＇s lengths of four optical signals have been found out respectively by simulating, and the according Q factor has been obtained.
