A cable structure includes at least one stuffing element, a first transmission module surrounding outside the at least one stuffing element, a first shielding layer surrounding outside the first transmission module, a second transmission module surrounding outside the first shielding layer, a second shielding layer surrounding outside the second transmission module, a woven layer surrounding outside the second shielding layer, an insulating skin surrounding outside the woven layer, a plurality of first core wire assemblies disposed in the first transmission module and the second transmission module, respectively, and at least one second core wire assembly disposed in the first transmission module or the second transmission module. A diameter of each first core wire assembly is different from a diameter of each second core wire assembly.

A twinaxial parallel cable includes two conductors arranged parallel to each other, an insulating layer formed around the two conductors by extrusion coating, a shield tape wound around the insulating layer while extending longitudinally, a drain wire arranged inside the shield tape, and an outer coating formed to cover the shield tape. A cross section of the insulating layer perpendicular to a longitudinal direction of the twinaxial parallel cable is formed into an oval shape having a long axis that is 1.7 to 2.2 times a length of a short axis. The insulating layer has a groove in a portion including an intersection of an outline of the insulating layer and a perpendicular bisector of the long axis. The groove is formed to be more than 0.5 times to 0.9 times an outer diameter or a thickness of the drain wire. The drain wire is retained in the groove so that a part of the drain wire protrudes toward the shield tape beyond the insulating layer.

The cable attaches a first component and a second component using a quick disconnect connector pair. The cable includes a twisted pair of wires with a separate shield. A portion of the shielding near the connector is removed to expose the wires and assemble the wires to the connector. To reduce the EMI leakage, the inner shell encloses the exposed portions of the wires. In order to maintain the ground path for the shielding of the shielded twisted wire pairs, the shielding for the twisted wire pairs is connected to the shell. The outer shells facilitate the quick disconnect feature. The outer shell includes one or more slots. The slot allows a portion of the outer shell to become a cantilever beam. The beam deflects during disengagement and engagement with the outer shell.

A fire-retardant data communication cable assembly including an outer coaxial jacket made out of fire-retardant material (e.g., Flourinated Ethylene Propylene (FEP)) coaxially enclosing optical and wire communication mediums, metal (e.g., copper) braid, metal (e.g., aluminum) foil, drain wire, and aramid fibers for substantially the entire length of the cable; a tube made out of fire-retardant material (e.g., Ethylene Tetrafluoroethylene (ETFE) or polyolefin) coaxially enclosing one or more optical communication mediums (e.g., optical fibers) and one or more aramid fibers for substantially the entire length of the cable; a fire-retardant coating (e.g., FEP) coaxially disposed over each of the one or more wire mediums for substantially the entire length of the cable.

A cable structure includes at least one stuffing element, a first transmission module surrounding outside the at least one stuffing element, a first shielding layer surrounding outside the first transmission module, a second transmission module surrounding outside the first shielding layer, a second shielding layer surrounding outside the second transmission module, a woven layer surrounding outside the second shielding layer, an insulating skin surrounding outside the woven layer, a plurality of first core wire assemblies disposed in the first transmission module and the second transmission module, respectively, and at least one second core wire assembly disposed in the first transmission module or the second transmission module. A diameter of each first core wire assembly is different from a diameter of each second core wire assembly.

A data communication cable assembly including a cable with wire and/or optical fiber communication mediums for transmitting data signals and/or power signals, and connectors for connecting to a pair of devices, respectively. Each of the connector includes a connector plug or receptacle configured to mate with a corresponding receptacle or plug of a device, wherein the connector plug or receptacle includes a set of electrical contacts configured to send and/or receive the data signals and/or power signals to and/or from the device; a metallic shell defining an enclosure and including first and second openings, wherein the connector plug or receptacle mate is configured to mate with the corresponding receptacle or plug of the device via the first opening, and wherein the cable extends from inside to outside of the enclosure via the second opening; and electrically-conductive filler material configured to reduce electromagnetic leakage via the first and second openings.

A telecommunications cable for making high resistance measurements comprising a plurality of bundles, each comprising a twisted pair of Category 6a copper conductors and a metal foil shield, one of said copper conductors in each twisted pair serving as a signal wire and the other of said copper conductors in each twisted pair being grounded to thereby serve as a noise ground; a braided grounded metal sheath surrounding said plurality of bundles of twisted pairs; and a grounded shield used as an outer sleeve, whereby said cable is triple grounded.

A data cable is provided herewith, along with related methods. The disclosed data cables may meet the requirements for a UL 2196 flame test, including subsequent hose stream test. The disclosed data cables include two or more pairs of conductors wrapped with a flame-retardant tape and surrounded by low smoke zero halogen (LSZH) thermoset insulation. A shield may surround the conductor pairs and a non-halogen flame retardant polyolefin may surround the shield. In certain embodiments, the pairs of conductors present in the cable may have different lay lengths.

A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is 1, the center-to-center spacing of the insulated conductors of the second conductor set is 2, and 1/2 is greater than 0.7.

A power/security cord for use in a retail display includes the combination of at least one spring steel strand and at least one conductor coiled into the shape of a curly-Q cord. The steel strand provides a physical barrier against cutting the cord. The conductor provides wiring for power.
