Abstract

A data cable with free stripping water blocking material includes a first conductor substantially surrounded by a first foam, a second conductor longitudinally adjacent the first conductor and substantially surrounded by a second foam, a solid coat substantially surrounding the first foam of the first conductor, a filler material, a shielding member, a water swellable tape, and a jacket. The first conductor with the first foam and the solid coat and the second conductor with the second foam are substantially placed within the filler material. The shielding member is placed substantially around the filler material. The water swellable tape is placed substantially around the shielding member. The jacket is placed substantially around the water swellable tape.

Claims

1. A data cable comprising:

a first conductor substantially surrounded by a first foam;

a second conductor longitudinally adjacent the first conductor, the second conductor substantially surrounded by a second foam;

a solid coat substantially surrounding the first foam of the first conductor;

a filler material within which the first conductor with the first foam and the solid coat and the second conductor with the second foam are substantially disposed;

a shielding member disposed substantially around the filler material;

a water swellable tape disposed substantially around the shielding member; and

a jacket disposed substantially around the water swellable tape.

2. The data cable according to claim 1, wherein the first conductor comprises a plurality of conductive strands.

3. The data cable according to claim 1, wherein the second conductor comprises a plurality of conductive strands.

4. The data cable according to claim 1, wherein the first conductor is a pair of conductors intertwined with each other.

5. The data cable according to claim 1, wherein the second conductor is a pair of conductors intertwined with each other.

6. The data cable according to claim 1, wherein the first conductor is a pair of conductors intertwined with each other with a first lay length;

and wherein the second conductor is a pair of conductors intertwined with each other with a second lay length that is longer than the first lay length.

7. The data cable according to claim 1, wherein the first and the second foam are made of high density polyethylene (HDPE).

8. The data cable according to claim 1, further comprising an insulation disposed substantially around the first and second conductors.

9. The data cable according to claim 1, wherein the solid coat is made of high density polyethylene (HDPE).

10. The data cable according to claim 1, wherein the filler material is substantially free stripping.

11. The data cable according to claim 1, further comprising a corewrap substantially disposed around the filler material.

12. The data cable according to claim 11, wherein the corewrap is made of mylar.

13. The data cable according to claim 1, wherein the shielding member comprises a tape made of aluminum and mylar.
