1. An optical fiber cable, comprising:
a plurality of tight-buffered ribbon stacks that are stranded about a longitudinal axis, wherein each of the tight-buffered ribbon stacks comprises
a plurality of optical fiber ribbons arranged in a stack; and
a buffer tube that is substantially conformal to the stack of the optical fiber ribbon;
a binder film that continuously and contiguously surrounds the plurality of tight-buffered ribbon stacks along the longitudinal axis such that the plurality of tight-buffered ribbon stacks are disposed within an interior region defined by the binder film, the interior region characterized by at least 40% of free space; and
a cable jacket that surrounds the binder film.
