1. A combined low attenuation optical communication and power cable comprising:
a cable body including a first end, a second end and an inner surface defining a channel within the cable body; a buffer tube located within the channel; a plurality of optical fibers located within the buffer tube, each optical fiber including a glass core, a first cladding layer having a first refractive index and a second cladding layer located outside of the first cladding layer having a second refractive index, wherein the second refractive index is less than the first refractive index; a plurality of copper electrical conducting elements located within the channel, wherein each of the copper electrical conducting elements has a diameter smaller than or equal to 16 AWG; a tensile strength fiber group located within the channel and extending between the first end and the second end of the cable body, the tensile strength fiber group located toward a central area of the channel such that the buffer tube is located between the tensile strength fiber group and the inner surface of the cable body and such that the copper electrical conducting element is located between the tensile strength fiber group and the inner surface of the cable body, wherein the fiber group includes at least two elongate aramid fibers; and a water absorbent polymer material attached to at least one of the aramid fibers of the tensile strength fiber group.
