Title: Fiber optic connector with optical attenuator

Abstract: The fiber optic connector with an optical attenuator includes a first end assembly, a second end assembly and an alignment sleeve. The first end assembly includes a bushing with a central bore and an optical fiber passing through the central bore. The second end assembly includes a bushing with a central bore and an optical fiber passing through the central bore. The alignment sleeve receives the first and second end assemblies and holds the two optical fibers in axial alignment. The alignment sleeve also holds a thin plastic or glass optical attenuator disc with a selected optical density between the two end assemblies. When the connector is held in a connector housing assembly, the axially aligned optical fibers have their ends in contact with opposite sides of the optical attenuator disc. A spring bias the optical fiber ends toward the optical attenuator disc. An optical attenuator disc with a different optical density can replace the disc in the alignment sleeve to change attenuation. An alignment sleeve with an optical attenuator disc can also be replaced by another alignment sleeve with an attenuator disc having a different optical density.
