... curvature, height of the fiber with respect to the polishedradius, and the distance between the apex of the spherical polish and the center of the fiber (apex offset). The spherical polish ... about the axis of the ferrule (See Figure 2). Because the ferrule is tilted in polish, more material is removed from oneside of the ferrule axis than the other. As Figure 2 shows, the angle on the ... left of the chamfer is notas steep relative to the angle on the right of the chamfer. As material is removed in polish, the surface of the endface becomes relatively larger on the left of the ferrule...
