Abstract
A communications cable is disclosed herein that includes an outer jacket, and either a core tube or at least one buffer tube. The core tube or at least one buffer tube includes a resin and high aspect ratio fillers that occupy a predetermined volume of the core tube or buffer tubes so as to impart crush resistance to the cable. Further, the core tube or buffer tube may include two layers, an outer layer and an inner layer, in which the outer layer includes both a resin and high aspect ratio fillers, and the inner layer includes the resin without the high aspect ratio fillers.
