Abstract: A self-cleaning optical fiber connector system for ensuring dust or contaminants are cleared from an optical connection interface is disclosed. In one aspect, the optical fiber connector system includes a connector joining first and second connectors. The adapter has a main body defining a central opening within which the connectors are received. The connectors each include a fiber optic cable secured by a ferrule. In one aspect, the ferrule defines an airflow passageway that narrows between a second opening and a first opening proximate an end face of the cable optical core and cladding. The connectors are constructed such that, as each connector is being inserted into the connector, an air flow is generated through the ferrule airflow passageway, and optionally through an exhaust airflow passageway in the connector. The generated airflow clears debris from the exposed end faces. Electrostatic precipitation may also be used to aid in clearing dust and debris, alone or in combination with air flow effects.
