Relative-Refractive-Index-Difference (Δ) dependence of intrinsic loss of GeO2-Doped graded index silica fibers is clarified in the practical range of 1Δ2% and λ1.5 µm. It is confirmed that the decisive factor of Δ dependence is ultraviolet absorption loss, and that the Δ dependence of scattering loss is small.
