摘要： A fiber optic cable can comprise technology for mitigating stress on optical fibers of the cable. The technology can protect the optical fibers from compression, such as stemming from installation, deployment, or handling. The technology can compensate for thermally induced expansion and contraction of cable elements having differing thermal expansion characteristics, arising when the cable is subjected to temperature variations. The cable can comprise a central strength member onto which an elastomeric material, such as silicone, has been applied. The elastomeric material can protect optical fibers that are located between the central strength member and an outside jacket.

摘要： A tape can comprise a dielectric film that has a pattern of electrically conductive areas adhering thereto. The conductive areas can be electrically isolated from one another. The tape can utilize means to obscure the metallic finish and can contain indicators to deter installers from grounding the tape at either end. The tape can be wrapped around one or more conductors, such as wires that transmit data, to provide electrical or electromagnetic shielding for the conductors. The resulting cable can have a shield that is electrically discontinuous between opposite ends of the cable.

摘要： A data communication cable can comprise multiple pairs of twisted conductors. A jacket that extends along the outside surface of the cable can define a longitudinal core, internal to the cable. The conductor pairs can be disposed in the core of the cable along with a foam matrix or a porous filler, with the matrix and the conductors occupying essentially all of the volume of the core. The foam matrix can hold each conductor pair in a respective location within the cable core to control signal crosstalk on each pair. A co-extrusion process can produce the cable via simultaneously extruding the foam matrix and the jacket. A pulling apparatus can feed the conductor pairs though respective ports of an extrusion head-and-die assembly. As one extruder encases the moving conductor pairs in the foam matrix, another extruder forms the jacket over the matrix and the embedded conductors.

摘要： A fiber optic cable can comprise a tape that extends along the cable and that facilitates locating the cable when the cable is buried underground. The tape can comprise a film of nonconductive material, such as plastic, with an overlaying pattern of conductive patches. The conductive patches can comprise regions of metallic film laminated with or otherwise adhering to the nonconductive film. Spacing between the conductive patches can provide patch-to-patch isolation so that the ends of the cable are electrically isolated from one another. Field personnel can locate the underground cable by scanning the ground with a metal detector.
