摘要： 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.

Abstract: We have measured dispersion of single-mode fibers by means of time domain and frequency domain methods at 0.82μm. Since single-mode fibers designed for longer wavelengths have 2 or 3 modes at this wavelength, it is necessary to separate ntermodal dispersion from singlemode dispersion. The two methods gave the same iresult.
