extruding a jacket adjacent to the scaffolding structure such that when the jacket is subjected to a burn and melts, the melted jacket material bonds to the scaffolding structure rather than sloughing off;
wherein the plurality of optical fibers is a plurality of optical fiber ribbons 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;
wherein the scaffolding structure is provided around the subunits without an intervening layer; and
wherein less than 60% of the cable jacket internal cross-sectional area is occupied by the cross-sectional area of the plurality of optical fibers.
