EB (Expanded Beam) connectors do not employ the normal 'butt-contact' design. Instead they feature a non-contact technique where the fiber is sealed behind a lens. Clever design minimizes back reflection or insertion losses. Expanded beam connectors have a high tolerance for dirt and debris, but even the best EB connectors, such as the OPTOKON expanded beam system, suffers from contamination in combat conditions. Best practices dictate that cleaning is performed routinely. But, the geometry of EB lenses mean that standard fiber optic cleaning tools simply will not work.
