摘　　要：作为表征光纤传输性能的重要参数,光纤的折射率分布直接影响着光纤的传输特性;进一步通过获得光纤折射率的分布来计算出光纤的几何参数以及光纤的最大理论数值孔径;等等。本文分析和讨论了光纤折射的依赖关系,重点讨论了光纤折射率与波长的关系,得出了它们之间的数学描述,实现了对光纤折射率与波长关系的定量研究。Optical fiber refractive index directly affects the intrinsic properties of the fiber,such as dispersion (orbandwidth),numerical aperture,mode field diameter (MFD),cutoff wavelength,normalized frequency,attenuation and soon. This paper analysis and discusses the dependence of the birefringence fiber,optical fiber refractive index and wavelengthare discussed,that between them the mathematical description,realized the quantitative research of optical fiberrefractive index as a function of wavelength.
