Abstract
A jacket for a communication cable is made from a resin that has high aspect ratio filler materials, and possibly coupling agents, dispersed therein. The fillers and the coupling agents reduce the post-extrusion shrinkage of the jacketing compound such that the strength members used in the communication cable need have only negligible compressive stiffness.
Claims18
A fiber optic cable comprising:
- an outer jacket for the cable, wherein the jacket comprises a resin;
- and high aspect ratio fillers of an aspect ratio of at least 10:1 occupying a predetermined volume of the jacket whereby post extrusion shrinkage of the jacket is controlled.
A dielectric fiber optic cable comprising:
- an outer jacket for the cable, wherein the jacket comprises
- a resin selected from the group consisting of:
- polyethylenes, ethylene-vinyl acetate copolymers, ethylene/propylene rubbers, ethylene-ethyl acrylate copolymers or impact-modified isotactic polypropylene, including copolymers of polypropylene and ethylene/propylene rubbers;
- fibrous fillers with an aspect ratio of at least 10:1;
- and
- a coupling agent to aid adhesion between the fillers and the resin and to aid dispersion of the fillers.
