  • Pivotable optical shutter for blocking emission from a lightguide adapter #5
    Patent number: 5687268
    Abstract: An optical shutter for use with optical fiber connector coupling adapters has a front, transverse face which is sufficient to cover the opening in the adapter. The transverse portion has a pair of pivot arms extending from either side thereof which are adapted, at their distal ends, to be pivotally connected to the coupling adapter, thereby providing a pivotal mounting for the shutter. The transverse face also has a flange extending from one end thereof to permit actuation of the shutter, i.e. opening or closing, by means of the connector to be inserted in the adapter, or after removal of the adapter.
