Abstract
A fiber optic connector having an adjustable element providing for optical signal attenuation. The connector includes a pair of plug connector elements maintained in axially aligned relation upon engagement with a medially positioned adapter element. One of the plug connector elements incorporates the adjustable element, movement of which varies the gap existing between the aligned ends of the optical fibers without relative rotation between the end surfaces of the fibers.
