A LAN cable includes an insulated electrical wire having an insulating layer on an outer periphery of a conductor, a sheath that coats an outer periphery of the insulated electrical wire, and an intermediate layer arranged between the sheath and the insulated electrical wire, the intermediate layer having a mass reduction rate at 800 C. of less than or equal to 80% by mass. The sheath includes a cross-linked matter or a non-halogen flame retardant resin composition in which a mass reduction rate at 800 C. is less than or equal to 60% by mass.

A signal transmission cable configurable to allow variable electromagnetic field transmission along a length thereof is disclosed herein. The signal transmission cable includes at least one inner signal wire, the at least one inner signal wire configured to convey a signal originating from a signal transmitter; a shielding layer circumscribing the at least one inner signal wire, the shielding layer configured to prevent an electromagnetic field from escaping exteriorly from the signal transmission cable; and an outer protective layer circumscribing the shielding layer, the outer protective layer configured to prevent damage to the shielding layer and the at least one inner signal wire. One or more portions of the outer protective layer and the shielding layer are configured to be selectively removed by a user so as to enable the electromagnetic field emanating from the signal transmission cable to be varied.

Embodiments describe a jacket for use in a telecommunications cable. The jacket includes a jacket body. The jacket body extends along a longitudinal axis of the telecommunications cable. The longitudinal axis passes through a geometrical center of the telecommunications cable. The jacket body includes a first surface. The first surface surrounds core region of the telecommunications cable. The first surface defines a plurality of grooves extending radially outwardly from the longitudinal axis of the telecommunications cable. The plurality of grooves includes a first groove area section and a second groove area section. The first groove area section and the second groove area section are in continuous contact with each other. In addition, the jacket body includes a second surface. The second surface extends along the longitudinal axis of the telecommunications cable and disposed in a spaced relation to the first surface.

A communication cable that includes a twisted wire pair that includes a pair of insulated wires that are twisted together and that each include a conductor and an insulating covering that covers an outer periphery of the conductor; and a sheath that is made of an insulating material and continuously covers an entire outer periphery of the twisted wire pair about a center along a longitudinal axis of the twisted wire pair, wherein the sheath has a dielectric loss tangent of 0.0001 or more in a frequency range of 1 to 50 MHz.

A twisted pair cable and unshielded cable using the twisted pair cable. The twisted pair cable comprises two core wires. Each core wire includes a conductor and an insulating layer wrapping the conductor. The two core wires are twisted together to form a twisted pair structure. The two core wires are bonded by an adhesive, resulting in a more stable structure.

A communication cable suitable for Power over Ethernet (PoE) applications may include one or more twisted pairs of individually insulated conductors that are insulated with a material that includes fluorinated ethylene propylene. Additionally, a jacket that includes foamed polyvinylidene fluoride may be formed around the one or more twisted pairs. The PoE cable may have a higher maximum temperature rating and be capable of transmitting higher amperage signals than conventional PoE cables while satisfying applicable electrical performance criteria.

Cables incorporating a separator positioned between two or more subcomponents are described. A separator may extend in a longitudinal direction and include a body portion having an asymmetrical cross-sectional. Additionally, an outer periphery of the body portion may define a plurality of longitudinally extending channels including a first channel having a first cross-sectional area and a second channel having a second cross-sectional area different than the first cross-sectional area. At least one cavity may optionally extend through the body portion along the longitudinal direction. A first cable subcomponent including first transmission media may be positioned within the first channel, and a second cable subcomponent including second transmission media may be positioned within the second channel. A jacket may be formed around the separator and the subcomponents.

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.
