Abstract: A dust shutter plate biased by a spring plate closed within a port of an adapter assembly with one or more receptacle ports configured to received and secure a fiber optic connector. The dust shutter plate may be coated with a cloth or gel to reduce light transmission losses or both. The angle of the spring plate ensures the plate coated makes contact with the ferrule endface to remove debris and coat the optical fibers at the endface. And if not a coated dust plate, the spring is angled to ensure the ferrule endface does not contact the dust shutter plate surface and damage the optical fiber therein. The dust shutter plate may have a plural of grooves on the connector facing side of the shutter plate.

Abstract: An array of dust shutter plate connected to a body by a flexible bridge member. The body holds one or more dust shutter plate, a corresponding bridge member, and an actuator that opens the dust shutter or moves the dust shutter plate from a closed position covering an opening in the alignment sleeve holder to an open position, so the connector ferrule can be accepted into an opening at one end of the alignment sleeve holder.
