An optical fiber cable structure including a tube comprised of inorganic fillers dispersed within a soft resin, the tube housing optical fibers or ribbons surrounded by a water blocking material. The use of the inorganic fillers in the soft resin provides a cable structure with superior blowing performance due to low surface friction and high flexibility, allowing more effective installation of the fiber optic cable via blowing techniques The use of the inorganic fillers in the soft resin also reduces the thermal expansion/contraction of the cable structure, and increases the compression resistance of the cable structure to axial loads, providing protection to the optical fibers.

Fiber optic cable structure and method

A jacket for an outside plant communication cable is made from a resin of an impact-modified polypropylene copolymer compounded with UV stabilizers. The resin has the characteristics of low cost, low post-extrusion shrinkage, high melting temperature and increased crush and abrasion resistance. The UV light stabilizers may include UV absorbers, quenchers, and/or hindered amine light stabilizers.

Communication cable having polypropylene copolymer jacketing material

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. The communication cable may further include a skin coating surrounding the outer jacket.

Communication cable having reduced jacket shrinkage

A protective cable armor for cable having tensile stiffness and providing structural protection from invasion by foreign objects. The armor comprises a substantially planar sheet member having a length and a width and an intermittent corrugation pattern disposed therein. The intermittent corrugation pattern comprises at least one land extending across the width of the sheet member and having a defined land width. The intermittent corrugation pattern further comprises at least one, groove extending across the width of the sheet member and having a defined groove width, where the defined land width differs from the defined groove width. The land is disposed adjacent the groove. The sheet member can also be disposed in a substantially tubular form.

Corrugated armor for providing protection and tensile stiffness

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.

Communication cable having enhanced crush resistance

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.
