Abstract

The present invention relates to a fiber optic device for the optically connecting optical fiber. The device consists of fiber optic connectors holding the terminal ends of optical fiber in ferrules and an adapter for receiving fiber optic connectors. The adapter includes a sleeve within a longitudinal opening which aligns the ferrules and the terminal end of the optical fiber held by the ferrules. Within the sleeve is placed an attenuator which extends across the longitudinal opening in the sleeve and is held at an angle to the longitudinal axis of the opening by slots in the sidewall of the sleeve. The angle at which the attenuator is held may be perpendicular or non-perpendicular to the longitudinal axis of the sleeve. The sleeve is further prevented from rotating within the adapter by pockets formed in the inner wall of the longitudinal opening engaging extensions of the attenuator beyond the sidewall of the sleeve. The adapter with a non-rotating sleeve and attenuator is disclosed to be adapted for use with a variety of formats of fiber optic connectors. The attenuator may be held within the adapter perpendicular to the longitudinal axis of the sleeve for use with PC, SPC, UPC or other ferrule ends, or for use with flat, perpendicular ferrule ends. The attenuator may also be held at non-perpendicular angles to the longitudinal axis of the sleeve, for use with angled flat ferrules, such as APC ferrules.
