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.

An optical shutter for use with one optical coupling adapter having an open end, said optical shutter comprising: a light blocking transverse member having first and second sides; a first pivot arm extending from said first side in a first direction at an angle to said transverse member, said pivot arm having a free distal end; a second pivot arm extending from said second side in said first direction, said second pivot arm having a free distal end; said first and second pivot arms being spaced apart a distance greater than the width of the coupling adapter; means for pivotally mounting said distal ends of said first and second pivot arms to the sides of the coupling adapter with said pivot arms straddling the coupling adapter; and means on said light blocking transverse member for actuating said shutter to block and to unblock the open end of the adapter.
