Abstract
An optical cable coupling adapter comprises two end portions and a split sleeve. Each end portion holds a plurality of cylindrical rods with their outer circumferences kept in contact with one another. The cylindrical rods define one or more passages for an optical fiber. The split sleeve contacts and holds the exposed outer circumferential surfaces of the cylindrical rods and effects center alignment of the fiber passages in the two end portions.
