摘要： Shielded twisted pair communication cables are described. A cable may include at least one twisted pair of insulated conductors, and an outer circumference may be defined by the twisted pair along a longitudinal length of the cable. A shield may be formed around the twisted pair, and a jacket may be formed around the shield. Additionally, a dielectric film may separate the insulated conductors of the twisted pair, and the dielectric film may extend beyond the outer circumference of the twisted pair and contact the shield.

摘要： A fiber optic cable can inhibit water, that may inadvertently enter the cable, from damaging the cable's optical fibers. The fiber optic cable can comprise buffer tubes extending along the fiber optic cable. The buffer tubes can be arranged such that a ring of buffer tubes surrounds one or more centrally located buffer tubes. Stacked ribbons of optical fibers can be disposed in each buffer tube, along with water-swellable tape and water-swellable yarn. The tape, yarn, and optical fibers can be dry or free from water-blocking gels or fluids. The water-swellable materials can provide an unexpected level of water protection. The water-swellable materials can, for example, limit flow of seawater within the buffer tubes. In an exemplary embodiment, progression of seawater can be limited to three meters or less for a twenty-four hour test period during which the seawater is under about one meter of head pressure.

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 inhibit water, that may inadvertently enter the cable, from damaging the cable's optical fibers. The fiber optic cable can comprise a buffer tube defining an interior volume extending along the fiber optic cable. Optical fibers can be disposed in the interior volume of the buffer tube, along with water-swellable materials, such as tapes and yarns. The interior volume can be dry or free from water-blocking gels or fluids. The water-swellable materials can provide the fiber optic cable with an unexpected level of protection from seawater. The water-swellable materials can, for example, limit flow of seawater along the interior volume. In an exemplary embodiment, progression of seawater in the interior volume be limited to three meters or less for a twenty four hour test period during which the seawater is under about one meter of head pressure.

摘要： A tape can comprise a two-sided strip of dielectric material, with patches of electrical conductive material adhering to each side. Patches on one side can be longitudinally offset from patches on the opposite side. The patches can be electrically isolated from one another. The tape can be wrapped around one or more conductors, such as wires that transmit data, to provide electrical or electromagnetic shielding. The patches can circumferentially encase the conductors, with patches on one side of the tape covering gaps on the other side of the tape. The tape can be wrapped around the conductors so that an edge of a patch spirals about the conductors in a rotational direction opposite to any twisting of the conductors. The resulting cable can have a shield that is electrically discontinuous between opposite ends of the cable.

摘要： A fiber optic cable can comprise spheres or balls that are coated with a water absorbent material, such as a super absorbent polymer (“SAP”). The spheres can provide clean and efficient carriers for introducing SAP into the cable during manufacturing. The spheres can have a diameter in a range of 20 microns to 2.5 millimeters and can be disposed in the cable's interstitial spaces, for example between the cable's optical fibers and a surrounding buffer tube. The SAP material can adhere to the spheres as a cross-linked coating or via electrostatic charge, for example. Beyond absorbing any water that may enter the cable, the spheres can provide cushioning or mechanical protection for the optical fibers. When the cable receives stress, motion among the spheres can absorb the stress to shield the fibers from damage.

摘要： A fiber optic cable can comprise small spheres or balls disposed in the cable's interstitial spaces, for example between the cable's optical fibers and a surrounding buffer tube. The spheres can comprise foam rubber, closed-cell or open-cell porous polymer, or some other soft material. Typical diameters for the spheres can be in a range of 1 to 2.5 millimeters. A soft composition of the spheres can cushion the optical fibers and physically impede water ingress into the cable. Additional fiber protection can arise from the ability of the loose spheres to rotate individually, in a ball-bearing effect. Thus, sphere-to-sphere motion can absorb physical stresses associated with bending, twisting, bumping, and stretching the cable during installation, thereby shielding the fibers from damage.

摘要： A data communication cable can comprise multiple pairs of twisted conductors within an outer jacket. A shielding can be disposed between the conductors and the outer jacket. The shielding may be an asymmetrically clad alloy steel (ACAS) tape wherein the copper cladding of the shield is thicker on a first side and thinner on a second side. When the tape is positioned between the conductors and the jacket, the thicker copper layer can be positioned adjacent to the conductors. The thicker copper layer can reduce the capacitive coupling between the conductors and the steel layer of the shielding tape without the added expense of an inner jacket or increased insulation thickness between the conductors and the shielding tape. The tape may also reduce lightning noise and other electromagnetic interference. Additionally, copper layers of the tape can help prevent corrosion of the inner steel layer.
