We quantitatively evaluated the impact of manufacturing tolerances on the optical properties of a five-tube Nested Antiresonant Nodeless Fiber (NANF) using Monte Carlo simulation combined with linear multiple regression sensitivity analysis. Confinement loss shows strong dependence on a core-size indicator derived from the mean radial perturbation, with additional contributions from tube-to-tube variability in nested-tube angular tilt. The effective refractive index difference is dominated by the second-order Fourier component of the tangential elliptical perturbation, S2a, while polarization-dependent loss could not be explained by the geometric features considered in this analysis.
