Abstract: A fiber optic cable includes a core comprising a plurality of cable subunits configured such that an outer group of cable subunits surrounds a central cable subunit. each cable subunit includes one or more optical fibers, a buffer tube surrounding the one or more optical fibers, a strength layer surrounding the buffer tube, and a subunit jacket surrounding the strength layer. A thin film outer sheath surrounds the core, wherein the thin film outer sheath loads the outer group of cable subunits normally to the central cable subunit such that contact between the outer group of cable subunits and the central cable subunit provides coupling therebetween, limiting axial migration of the outer group of cable subunits relative to the central cable subunit.

Abstract: Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a cable jacket having an inner surface and an outer surface in which the inner surface defines a central bore along a longitudinal axis of the optical fiber cable and the outer surface defines the outermost extent of the cable. One or more embodiments of the cables described herein have improved bending characteristics and performances, respond positively to thermal cycling tests, provide improved anti-buckling characteristics, and have a reduced production cost compared to other known cables.
