Patent ID: 7897873

Claim:
A communications cable, comprising: at least one conducting element; and a dielectric jacket encasing the at least one conducting element, wherein the dielectric jacket comprises an inner layer of a first polymeric material selected from the group which includes polyolefins, polyamides, polyurethanes and polyvinyl chlorides, and an outer layer of a second polymeric material selected from the group which includes fluoroethylenepropylene (FEP), ethylenechlorotrifluoroethylene (ECTFE), perfluoroalkoxy polymers (PFA), polytetrafluoroethylene (PTFE), and ethylene tetrafluoroethylene (ETFE), wherein the jacket has a substantially constant cross-sectional configuration along a length of the cable, and wherein the outer layer has a thickness of between about five and ten thousandths of an inch (0.005″-0.010″) and has an outer surface with a coefficient of friction of between about 0.05-0.4.
