  • Abstract
    The differential mode attenuation αm(λ) in the spectral region of OH absorption (1.2-1.6 μm) has been studied in SiO2/GeO2 core graded-index fibres. It was found that the mode attenuation due to OH absorption Km(λ) at 1.39 μm had its maximum in the fibre core centre. The comparison between the calculated and measured Km(λ) at this wavelength could be used for the determination of OH-ion distribution profile in optical fibres.
