1. A cable comprising:
a plurality of optical fibers forming a fiber bundle that is loosely disposed within an enclosure, wherein the enclosure is formed by a plurality of keystones arranged about the fiber bundle, and wherein a gap between the fiber bundle and an interior of the enclosure, cumulatively, is a cumulative gap that is between 0.004 inches and 0.008 inches;
at least one conductor layer disposed about the enclosure;
a first layer disposed between the plurality of keystones and the at least one conductor layer, the first layer being selected from a group consisting of a layer of metallic or thermoplastic tape, a layer of metal wires or strands, and a layer of fibers;
an insulation layer disposed about the at least one conductor layer;
an inner layer of armor strength members helically disposed about the insulation layer;
an inner jacket disposed between the insulation layer and the inner layer of armor strength members, wherein the inner jacket contacts the insulation layer,
an outer layer of armor strength members helically disposed about the inner layer of armor strength members, wherein the armor strength members in the outer layer of armor strength members are at an opposite helix compared to the armor strength members in the inner layer of armor strength members;
an intermediate jacket disposed between the inner layer of armor strength members and the outer layer of armor strength members that isolates at least a portion of the inner layer of armor strength members from the outer layer of armor strength members; and
an outer jacket disposed about the outer layer, wherein the outer jacket comprises a short-fiber reinforced polymer that is reinforced with strength fibers such that a tensile elongation of the outer jacket is greater than 15%.
