A cable may include a plurality of twisted pairs of individually insulated conductors and a separator positioned between the twisted pairs. The separator may be formed from a tape that is scored at a plurality of respective spaced locations along a longitudinal direction.

The tape may then be twisted along the longitudinal direction such that a first of the plurality of sections extends in a first direction between a first set of adjacent twisted pairs and a second of the plurality of sections extends in a second direction different than the first direction and between a second set of adjacent twisted pairs. A jacket may be formed around the twisted pairs and the separator.

A USB cable having at least two pairs of strands, each pair designed to transmit a differential data signal in the longitudinal direction (L) of the cable, the strands extending helically about a common braiding center such that at least one additional wire pair does not have a separate shield, wherein the wires of the additional wire pair are arranged at a distance from one another on opposite sides of the stranding center.

A communication cable suitable for Power over Ethernet applications may include a jacket that defines a cable core and a plurality of twisted pairs of conductors disposed within the cable core. Each of the conductors may have a diameter of at least approximately 0.0240 inches or the equivalent of a 22 American Wire Gauge conductor. Additionally, each of the plurality of twisted pairs may have a different twist lay, and the respective twist lays may be selected such that the communications cable satisfies the requirements of a Category 6A cabling standard.

The present disclosure relates to a telecommunications cable. The telecommunications cable includes a plurality of twisted pairs of insulated conductors. The plurality of twisted pairs of insulated conductors extends substantially along a longitudinal axis of the telecommunications cable. In addition, the telecommunications cable includes a separator. The separator separates each twisted pair of insulated conductor of the plurality of twisted pairs of insulated conductors. Moreover, the telecommunications cable includes a first layer. The first layer surrounds the separator and the plurality of twisted pairs of insulated conductors along a length of the telecommunications cable. The separator is I-shaped filler. The separator is made of low smoke zero halogen material or MDPE. The first layer is made of low smoke zero halogen material, polyethylene or poly vinyl chloride. The first layer has a thickness in a range of about 0.4 millimeter-2.5 millimeters.

The present invention relates to an improved insulated conductor with a low dielectric constant and reduced materials costs. The conductor (12) extends along a longitudinal axis and an insulation (14, 14<1>) surrounds the conductor (12). At least on channel (16, 16<1>) in the insulation (14, 14<1>) extends generally along the longitudinal axis to form an insulated conductor. Apparatuses and methods of manufacturing the improved insulated conductors are also disclosed.

Two electromagnetic interference (EMI) controlling tape application methodologies for unshielded twisted pair (UTP) cable include Fixed Tape Control (FTC) and Oscillating Tape Control (OTC). In FTC, tape application angle and edge placement are controlled to maintain position of the tape edges over a base of nonconductive filler in the cable. In OTC, the tape application angle is continuously varied, resulting in crossing of the tape edges over all of the pairs of conductors with varying periodicity. In both implementations, the filler allows a cylindrical shape.

The present disclosure provides 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 cable may include a plurality of twisted pairs of individually insulated conductors, a separator positioned between the twisted pairs, and a jacket formed around the twisted pairs and the separator.
