A fiber optic cable, comprising: at least one optical fiber, the at least one optical fiber being a microstructured optical fiber; a protective covering including a buffer layer and a jacket, the buffer layer disposed about the at least one optical fiber; the jacket providing a bend radius control mechanism for inhibiting bending of the at least one optical fiber at a diameter of about two times the radius of the fiber optic cabled; a plurality of strength members disposed between the buffer laver and the jacket in a parallel configuration; the bend radius control mechanism comprising a flexibility of the jacket defined by a jacket material having an ultimate elongation of about 500% or more measured according to German measurement standard DIN 53504 and a pressure extruded coupling of the jacket to the plurality of strength members, wherein the coupling results in very little to no construction stretch for the strength members, with construction stretch meaning that all of the cable components are not simultaneously stretched when applying a tensile force to the fiber optic cable, whereby if the fiber optic cable exhibits construction stretch, then the fiber optic cable has the jacket and optical fiber supporting the initially applied tensile force but the strength members do not support the initially applied tensile force, therefore in this case the jacket and optical fiber are stretched to a point where a slack in the strength members is removed and the strength members also begin to support the load and a buckling of the at least one optical fiber in the jacket is inhibited by the coupling when the tensile force is removed, wherein the fiber optic cable is designed to have enough coupling between protective covering and optical fiber to inhibit buckling of the optical fiber within protective covering, wherein the fiber optic cable has a delta attenuation of about 0.33 dB or less when wrapped 3 turns about a 7.5 millimeter mandrel at a reference wavelength of 1625 nanometers. at least one optical fiber, the at least one optical fiber being a microstructured optical fiber; a protective covering including a buffer layer and a jacket, the buffer layer disposed about the at least one optical fiber; the jacket providing a bend radius control mechanism for inhibiting bending of the at least one optical fiber at a diameter of about two times the radius of the fiber optic cabled; a plurality of strength members disposed between the buffer laver and the jacket in a parallel configuration; the bend radius control mechanism comprising a flexibility of the jacket defined by a jacket material having an ultimate elongation of about 500% or more measured according to German measurement standard DIN 53504 and a pressure extruded coupling of the jacket to the plurality of strength members, wherein the coupling results in very little to no construction stretch for the strength members, with construction stretch meaning that all of the cable components are not simultaneously stretched when applying a tensile force to the fiber optic cable, whereby if the fiber optic cable exhibits construction stretch, then the fiber optic cable has the jacket and optical fiber supporting the initially applied tensile force but the strength members do not support the initially applied tensile force, therefore in this case the jacket and optical fiber are stretched to a point where a slack in the strength members is removed and the strength members also begin to support the load and a buckling of the at least one optical fiber in the jacket is inhibited by the coupling when the tensile force is removed, wherein the fiber optic cable is designed to have enough coupling between protective covering and optical fiber to inhibit buckling of the optical fiber within protective covering, wherein the fiber optic cable has a delta attenuation of about 0.33 dB or less when wrapped 3 turns about a 7.5 millimeter mandrel at a reference wavelength of 1625 nanometers.
