The invention relates to the technical field of cables, in particular to a self-supporting optical cable with marking strips. The self-supporting optical cable with the marking strips is formed by a cable core, an outer protecting sleeve wrapping the cable core, a strengthening element, a suspension wire protecting layer wrapping the strengthening element and a rib enabling the suspension wire protecting layer and the outer protecting sleeve to be connected. The cable core is formed by a central strengthening piece located in the center, a plurality of loose sleeve pipes located outside the central strengthening piece and a protecting layer. Optical fibers are arranged in the loose sleeve pipes. The self-supporting optical cable with the marking strips is characterized in that the strengthening element is made of a steel wire or glass fiber strengthening plastic, the two marking strips are symmetrically arranged on the suspension wire protecting layer, and the suspension wire protecting layer, the outer protecting sleeve and the rib are formed integrally and are made of identical materials. The invention further discloses the components and proportions of the marking strips. The self-supporting optical cable with the marking strips has the advantages that the thickness of the suspension wire protecting layer is more convenient to control, more smooth and round, products can be produced faster and are higher in qualified rate, the optical fibers are lower in self-weight and longer in adaptive span, and the color of the marking strips is more stable.
