First Claim
Patent Images
1. 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.

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.
