Abstract
A dust cover for protecting a sleeve housing of a fiber optic adapter having opposed interior sidewalls is provided, which includes an elongate member having first and second opposed ends wherein the elongate member has a multifaceted outer surface with at least one planar surface for engaging the opposed interior sidewalls of the fiber optic adapter. The first end of the elongate member is sized and shaped to align the elongate member within the fiber optic adapter and receive the sleeve housing. The first end of the elongate member also includes a longitudinally extending central bore for receiving the sleeve housing and a plurality of landings, which are contiguous the longitudinally extending bore, and which are tapered toward the second end. The landings securely hold the sleeve housing within the central bore of the elongate member. With this arrangement, the dust cover prevents contamination to the optical fiber, is self-aligning, is accessible in panels having deep recesses, and is easily removable from fiber optic adapters, thereby overcoming limitations found in conventional dust covers.
