对三包层的大负色散、负色散斜率的色散补偿光纤进行了理论研究，分析了各个参量对色散曲线的调节作用，发现色散补偿光纤只有在一定范围的拉丝芯径内，以牺牲负色散数值才能获得大负色散斜率；采用在光纤拉丝时旋转预制棒的工艺减小了光纤的偏振模色散，并进一步改进国内已有的改进的化学汽相沉积（ＭＣＶＤ）光纤生产工艺，研制出了较高水平的色散补偿光纤。
The theory of dispersion compensation fiber with large negative dispersion and negative dispersion slope is studied theoretically. The effect of each parameter on the dispersion curve is analyzed. It is found that the dispersion compensation fiber only needs to be within the range of drawing core diameter at the expense of negative dispersion The value can obtain a large negative dispersion slope; the use of spinning the preform rod in the process of drawing the fiber to reduce the polarization mode dispersion of the fiber, and to further improve the existing domestic production of improved chemical vapor deposition (MCVD) fiber, developed Higher level of dispersion compensating fiber.
