Classification: CPC G | IPC G

Claim 0:
1. An optical fiber cable comprising:
a cable jacket comprising an inner surface and an outer surface, the inner surface defining a central bore along a longitudinal axis of the optical fiber cable and the outer surface defining an outermost extent of the optical fiber cable;
at least one access feature disposed in the cable jacket between the inner surface and the outer surface;
a plurality of optical fiber bundles, each of the optical fiber bundles comprising a plurality of optical fiber ribbons held in the optical fiber bundle with a wrap, each of the optical fiber ribbons comprising a plurality of optical fibers arranged in a planar configuration;
a plurality of strengthening yarns disposed in the cable jacket between the interior surface and the exterior surface;
wherein the optical fiber cable bends uniformly in all directions transverse to the longitudinal axis of the optical fiber cable;
wherein the plurality of strengthening yarns comprise a linear density of 1000 dtex to 5000 dtex;
wherein each of the optical fiber bundles comprises a first section, a second section, and a third section, the first section and the second section each comprising optical fiber ribbons each having a first number of optical fibers, the third section being disposed between the first section and the second section and comprising optical fiber ribbons each having a second number of optical fibers, the second number being greater than the first number; and
wherein the wrap defines an octagonal shape for each of the optical fiber bundles.
