Finned jackets for LAN cables

A cable comprising:

• a first twisted wire pair including first and second conductors, each separately surrounded by an insulation, wherein the first conductor and the second conductor are continuously twisted about each other along a length of the cable;
• a second twisted wire pair including third and fourth conductors, each separately surrounded by an insulation, wherein the third conductor and the fourth conductor are continuously twisted about each other along the length of the cable;
• a jacket surrounding the first and second twisted wire pairs, wherein said jacket has an outer circumferential wall with a generally circular cross sectional shape, and an inner circumferential wall, also having a generally circular cross sectional shape;
• and
• a plurality of protrusions extending away from said inner circumferential wall of said jacket generally toward a center of said cable, wherein surfaces of said inner circumferential wall between adjacent projections are arc-shaped following said generally circular cross sectional shape of said inner circumferential wall, and wherein ends of said plurality of protrusions abut said first and second twisted wire pairs to hold said first and second twisted wire pairs away from said inner circumferential wall of said jacket.

A cable comprising:

• a plurality of conductors;
• a cable jacket formed of a dielectric material and formed to surround said plurality of conductors, wherein said cable jacket has an outer circumferential wall with a generally circular cross sectional shape, and an inner circumferential wall, also having a generally circular cross sectional shape;
• and
• a plurality of protrusions formed of a dielectric material extending away from said inner circumferential wall of said cable jacket generally toward a center of said cable, wherein said plurality of protrusions cause an air gap between said plurality of conductors and said inner circumferential wall of said jacket.

A cable comprising:

• a first twisted wire pair including first and second conductors, each separately surrounded by an insulation, wherein the first conductor and the second conductor are continuously twisted about each other along a length of the cable;
• a second twisted wire pair including third and fourth conductors, each separately surrounded by an insulation, wherein the third conductor and the fourth conductor are continuously twisted about each other along the length of the cable;
• a jacket surrounding the first and second twisted wire pairs;
• and
• a plurality of protrusions extending away from a circumferential surface of said jacket, wherein said circumferential surface is an outer circumferential surface of said jacket, and said plurality of protrusions extend generally away from a center of said cable.

A cable comprising:

• a plurality of conductors;
• a cable jacket formed of a dielectric material and formed to surround said plurality of conductors;
• and
• a plurality of protrusions extending away from an outer circumferential surface of said cable jacket.
