Communications cables having outer surface with reduced coefficient of friction and methods of making same

摘要

A communications cable is made by providing at least one conducting element, and co-extruding first and second polymeric materials around the at least one conducting element to form a dielectric jacket encasing the at least one conducting element. The at least one conducting element may include at least one electrical conductor, and/or at least one optical fiber. The dielectric jacket has a substantially constant cross-sectional configuration along a length of the cable and comprises an inner layer formed from the first polymeric material and an outer layer formed from the second polymeric material. The outer layer has an outer surface with a coefficient of friction within the range of about 0.05-0.40, and a thickness of between about five and ten thousandths of an inch (0.005″-0.010″).
