We report a theoretical characterization of a commercial large mode area endlessly single mode photonic crystal fiber, i.e. the LMA-15 fiber produced by Crystal Fibre A/S. For the study, we employed a finite element leaky mode solver developed in earlier work. Based on the computed confinement loss of the modes, we found that as opposed to the claim of the factory, the fiber is obviously multi-moded in the visible light regime, even for a rather long fiber length. Additionally, we also computed the dispersion of the fundamental mode which agrees nicely to the measured results given by the factory's datasheet.
