| 摘 要： | 对五包层色散补偿光纤进行了研究,分析了各个参量对色散补偿光纤性能的影响,发现色散补偿光纤只有在一定范围的拉丝芯径内,以牺牲负色散数值为代价才能获得较大的负色散斜率。在1550nm处获得了不大于150ps/(nm·km)的负的总色散和负色散斜率的色散补偿光纤。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,并采用化学汽相沉积(MCVD)光纤生产工艺,研制出了性能较好的色散补偿光纤。

| Abstract: | Through the research on quintuplicate DCF, some parameters about the performance of the dispersion compensation fiber are analyzed, only in some range of drawbench radius, a big negative dispersive slope can be achieved at the expense of the negative dispersive value. The dispersion compensation fiber with negative dispersive slope, in which the dispersive value does not exceed 150 ps/(nm·km), is obtained at 1550 nm wavelength. The dispersion-compensation fiber can be manufactured by MCVD, and with the use of the technology about the rolling fiber performing bars on drawbench, the polarization-mode dispersion of the fiber is reduced. |
