Hollow Core Inhibited Coupling Fibers are experiencing an impressive reduction of their propagation loss. Despite that, there is still a difference between experimental loss and the theoretical minimum defined by confinement loss. This difference is assumed to be due to additional losses caused by geometrical irregularities of the real fibers compared to the ideal geometry, due to the fabrication process. In this work, we numerically investigate additional losses coming from several kinds of geometrical imperfections, highlighting their impact in defining fiber total loss.
