Fiber optic cable with rollable ribbon included in the central tube, without the intended twist

摘要

To provide an optical fiber cable with rollable ribbons contained in a central tube without intended stranding.SOLUTION: An optical fiber cable 10 includes a bundle of two or more non-twisted, rollable optical fiber ribbons 12 within a central tube 14. The bundle of non-twisted, rollable optical fiber ribbons defines a fiber packing density within the central tube of 6.5 to 8.5 fibers per square millimeter.SELECTED DRAWING: Figure 1
