1. An optical fiber cable comprising:
an outer jacket comprising a first inner surface and a first outer surface defining an outermost surface of the optical fiber cable, the first inner surface defining a central bore extending in a longitudinal direction between a first end and an opposing second end of the outer jacket; and
a first optical fiber carrying subunit and a second optical fiber carrying subunit stranded through the central bore of the outer jacket in an S-Z stranding pattern, wherein each of the first optical fiber carrying subunit and second optical fiber carrying subunit comprises a subunit jacket defining an inner bore and a plurality of optical fibers located within the inner bore of the subunit jacket;
wherein the plurality of optical fibers in the first optical fiber carrying subunit are twisted within the first subunit jacket in a first rotational direction as the first optical fiber carrying subunit extends from the first end to the second end of the outer jacket;
wherein the plurality of optical fibers in the second optical fiber carrying subunit are twisted within the second subunit jacket in a second rotational direction opposite the first rotational direction as the second optical fiber carrying subunit extends from the first end to the second end of the outer jacket; and
wherein the subunit jacket of the first optical fiber carrying subunit contacts the subunit jacket of the second optical fiber carrying subunit.
