Polymer composition for fiber optic cable having low thermal strain and methods of manufacturing the same

An extruded polymer article, the polymer article having a longitudinal axis generally in the direction of extrusion, the polymer article comprising:

• a polymer composition, comprising:
• a polyolefin;
• and
• at least 30% by weight of a thermoplastic elastomer;
• wherein the polymer composition has an elastic modulus of less than 2000 MPa and a thermal contraction stress of less than 3.0 MPa as measured using dynamic mechanical analysis (ASTM D4065).

A cable comprising:

• at least one communication element;
• a polymeric jacket that surrounds the at least one communication element;
• wherein the polymeric jacket is formed at least in part from a polymer composition comprising:
• a polyolefin;
• and
• at least 30% by weight of a thermoplastic elastomer;
• wherein the polymer composition is extruded to form the polymeric jacket, the polymeric jacket defining a longitudinal axis generally in the direction of extrusion;
• wherein the polymer composition has an elastic modulus of less than 2000 MPa and a thermal contraction stress of less than 3.0 MPa as measured using dynamic mechanical analysis (ASTM D4065).
