1. An optical fiber cable, comprising:
a central strength member extending along a longitudinal axis of the optical fiber cable;
a first plurality of tight-buffered ribbon stacks that are SZ-stranded around the central strength member, wherein an interstitial space is provided between adjacent tight-buffered ribbon stacks;
a binder film that continuously and contiguously surrounds the first plurality of tight-buffered ribbon stacks along the longitudinal axis, the binder film comprised of at least one of linear low-density polyethylene, a polyester, a polyamide, or a copolymer of polypropylene, the binder film being drawn into at least one interstitial space between adjacent tight-buffered ribbon stacks of the plurality of tight-buffered ribbon stack; and
a cable sheath that continuously and contiguously surrounds the binder film along the longitudinal axis.
