Abstract
Disclosed here are embodiments of an optical fiber ribbon. In the optical fiber ribbon, a plurality of optical fibers are arranged in a row. The optical fibers are embedded in a primary matrix. The primary matrix comprises a base resin and an opacifier pigment. A secondary matrix is disposed around the primary matrix, and a layer of printing is disposed between the primary matrix and the secondary matrix. The secondary matrix has a contrast ratio of from 0.2 to 0.9 as measured according to ASTM D2805. Embodiments of a method of preparing an optical fiber ribbon are also disclosed in which optical fibers are arranged in a row and embedded in a primary matrix. Characteristics of the optical fibers is printed onto the primary matrix, and the primary matrix is coated with a secondary matrix having a contrast ratio of from 0.2 to 0.9 according to ASTM D2805.
