Abstract :
The letter investigates the dispersion of GeO2 glass core and F-doped GeO2 glass cladding single-mode optical fibre. It is estimated that the total dispersion goes to zero at about ¿ = 1.77 ¿m. The material dispersions of these glasses are also measured. Material dispersion of GeO2 glass, which contains fluorine of 0.41 wt%, vanished at ¿ = 1.722¿m. This occurs at ¿ = 1.734 ¿m for pure GeO2 glass.
