Abstract
An optical fiber storage reel has a central axis of rotation and a plurality of arcuate surface members extending radially and spaced about the axis of rotation. Each arcuate surface has a radius of curvature that is equal to or greater than the critical bend radius of the optical fiber. The arcuate surfaces are spaced from the axis of rotation a distance such that a cable wound on the reel has a substantially straight line path between the arcuate surfaces, with the sum total of the straight line distances being sufficient to reduce the false loss readings on the cable which can occur when a cable is wound upon a circular drum or hub.
