1. A fiber optic cable comprising:
a plurality of optical fibers;
a core tube surrounding the plurality of optical fibers;
a thixotropic gel filling an interstitial space among the plurality of optical fibers within the core tube, wherein the thixotropic gel increases a hoop strength applicable to the core tube;
an intermediate layer surrounding the core tube, wherein the intermediate layer comprises a plurality of linear elements wrapped about the core tube to provide a predetermined tensile strength to the fiber optic cable without overcoming the hoop strength of the core tube; and
an outer layer surrounding the intermediate layer, wherein the outer layer comprises a combination of a moisture-cure cross-linked material and an activation catalyst masticated and extruded onto the intermediate layer.
