Abstract

A dust cap is particularly constructed for capping an adapter of the type that receives connectors terminating two optical fibers in respective ferrules. In one instance an optical connector may be received in one end of the adapter and the dust cap may be received in another end of the adapter, opposite the connector. The dust cap is at least partially translucent or transparent, and constructed so that light passing from one ferrule of the optical connector is preferentially directed toward a first location of the dust cap and light, and light passing from the other ferrule of the optical connector is preferentially directed toward a second location of the dust cap that is spaced from the first location.
