A light-blocking safety shutter is mounted in a fiber-optic adapter housing that mates with a standard fiber-optic male connector of the type with a fiber-containing ferrule protruding from a forward end. The shutter is mounted in the insertion passage of the adapter and is held in the light-blocking position by the cantilever manner in which the shutter is attached. The shutter may have several different shapes depending on the type of adapter in which it is mounted, including a shutter with a flat bumper panel or a shutter with raised dimple on the bumper panel. The bumper panel contacts the body of the inserted connector and takes the force that opens the shutter so that the ferrule is protected from contacting the shutter. The fiber-optic adapter may include one or more housings for receiving one or more fiber-optic male connectors, whereby the housing includes a shutter mounted in a cantilevered manner.
