The cable has a plurality of twisted pair conductors and a jacket surrounding said twisted pair conductors. The jacket includes a plurality of either ridges, valleys or both, disposed substantially perpendicular to the longitudinal axis of the cable, the ridges and/or valleys are dimensioned and spaced apart in a manner sufficient to create an air passage when the cable is arranged adjacent to and abutting other cables. ## Claims ### Claim 1 An arrangement of two or more adjacently positioned cables, said cables configured for tandem communication and power transmission, said cable arrangement comprising: two or more adjacently positioned cables configured for tandem communication and power transmission, each cable having: a plurality of twisted pair conductors; at least one power transmission conductor; and a jacket surrounding said twisted pair conductors, wherein said jacket includes a plurality of ridges disposed perpendicular to the longitudinal axis of said cable said ridges dimensioned and spaced apart in a manner sufficient to create a plurality of spaced apart air passages between said adjacent cables, said air passages being perpendicular to the longitudinal axes of said adjacent cables. ### Claim 2 (depends on 1) The cable arrangement as claimed in claim 1, wherein said cable has four twisted pair conductors. ### Claim 3 (depends on 1) The cable arrangement as claimed in claim 1, wherein said jacket is a polymer jacket. ### Claim 4 (depends on 1) The cable arrangement as claimed in claim 1, wherein said ridges extend from the surface of said jacket substantially 50%-100% of a thickness of said jacket. ### Claim 5 (depends on 1) The cable arrangement as claimed in claim 1, wherein said ridges are formed on said jacket as additional material deposited onto said jacket directly after extrusion when said jacket is in a semi-molten state. ### Claim 6 (depends on 1) The cable arrangement as claimed in claim 1, wherein said ridges are formed on said jacket as an additional material of jacket polymer surged periodically during the extrusion of said jacket. ### Claim 7 (depends on 1) The cable arrangement as claimed in claim 1, wherein said ridges are formed independently of said jacket in a second stage after said jacket is extruded and cooled. ### Claim 8 (depends on 1) The cable arrangement as claimed in claim 1, wherein said ridges are disposed as spaced apart ridges, each extending entirely around the circumference of said jacket, substantially perpendicular to the longitudinal axis of said cable. ### Claim 9 (depends on 1) The cable arrangement as claimed in claim 1, wherein said ridges are disposed as spaced apart ridges, each extending part way around the circumference of said jacket in partial arcs, substantially perpendicular to the longitudinal axis of said cable. ### Claim 10 An arrangement of two or more adjacently positioned cables, said cables configured for tandem communication and power transmission, said cable arrangement comprising: two or more adjacently positioned cables configured for tandem communication and power transmission, each cable having a plurality of twisted pair conductors; at least one power transmission conductor; and a jacket surrounding said twisted pair conductors, wherein said jacket includes a plurality of valleys disposed perpendicular to the longitudinal axis of said cable said valleys dimensioned and spaced apart in a manner sufficient to create a plurality of spaced apart air passages between said adjacent cables, said air passages being perpendicular to the longitudinal axes of said cables. ### Claim 11 (depends on 10) The arrangement cable as claimed in claim 10, wherein said cable has four twisted pair conductors. ### Claim 12 (depends on 10) The arrangement cable as claimed in claim 10, wherein said jacket is a polymer jacket. ### Claim 13 (depends on 10) The arrangement cable as claimed in claim 10, wherein said valleys are cut into the surface of said jacket substantially 50% of a thickness of said jacket. ### Claim 14 (depends on 10) The arrangement cable as claimed in claim 10, wherein said valleys are cut into said jacket directly after extrusion when said jacket is in a molten state. ### Claim 15 (depends on 10) The arrangement cable as claimed in claim 10, wherein said valleys formed on said jacket are cut after said jacket is extruded and cooled. ### Claim 16 (depends on 10) The arrangement cable as claimed in claim 10, wherein said valleys are disposed as spaced apart valleys, each extending entirely around the circumference of said jacket, substantially perpendicular to the longitudinal axis of said cable. ### Claim 17 (depends on 10) The arrangement cable as claimed in claim 10, wherein said valleys are disposed as spaced apart valleys, each extending part way around the circumference of said jacket in partial arcs, substantially perpendicular to the longitudinal axis of said cable. ### Claim 18 An arrangement of two or more adjacently positioned cables, said cables configured for tandem communication and power transmission, said cable arrangement comprising: two or more adjacently positioned cables configured for tandem communication and power transmission, each cable having: a plurality of twisted pair conductors; at least one power transmission conductor; and a jacket surrounding said twisted pair conductors, wherein said jacket includes a plurality of ridges and valleys disposed perpendicular to the longitudinal axis of said cable said ridges and valleys dimensioned and spaced apart in a manner sufficient to create a plurality of spaced apart air passages between said adjacent cables, said air passages being perpendicular to the longitudinal axes of said when said cable is arranged adjacent to and abutting other cables.
