本项研究完成了在短波长(0.82μm)处测量单模光纤的工作.长波长单模光纤在短波长处工作,存在单模色散与模间时延两种色散.本工作以频域与时域两方法完成了这两类色散的分离.测量结果表明,频域法与时域法基本一致.在0.82μm处的单模色散在85～130ps/km·nm之间.
This work has completed the work of measuring single-mode optical fiber at short wavelength (0.82μm) .The long-wavelength single-mode optical fiber works at short wavelength and has two kinds of dispersion, single mode dispersion and mode delay.This work uses frequency domain and time The two methods are used to separate the two types of dispersion, and the results show that the frequency domain method is basically the same as the time domain method, and the single mode dispersion at 0.82μm is between 85 and 130ps / km · nm.
