wherein the plurality of optical fiber ribbons is arranged in a plurality of ribbon stacks that define a plurality of subunits;
wherein each subunit has a subunit jacket that conforms to a shape of the ribbon stack;
wherein the plurality of subunits is unstranded within the cable jacket; and
wherein the scaffolding structure is provided around the subunits without an intervening layer.
