Abstract

In an optical fiber ribbon including a plurality of optical fibers arranged in a common plane in generally side-by-side relationship and surrounded by a layer of matrix material, at least one stress concentration is formed in the matrix material surrounding the optical fiber ribbon. The stress concentration extends along at least a portion of the ribbon parallel to a longitudinal axis of the ribbon and concentrates stress applied to the ribbon such that the matrix material easily separates at the stress concentration. Each stress concentration may be formed directly in the matrix material during its application on the optical fibers, or an abrasive surface may be applied to the fiber to form the stress concentration. Stress concentrations may formed on at least one extreme edge of the optical fiber ribbon such that the entire matrix material may be easily removed from a section of optical fiber ribbon at a desired ribbon access location. Alternatively, stress concentrations may be formed on at least one of the major surfaces of the optical fiber ribbon at designated locations where it is desired for the optical fiber ribbon to be separated into smaller groups or sub-ribbons.
