Provided herein is a multi-core cable through which positions of a plurality of insulated conductors and a plurality of non-insulated conductors in a cross section in a longitudinal direction are changed and a likelihood of transmission performance being reduced is low. A multi-core cable includes n conductor bundles.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

A cable includes an insulative main jacket, a main conductive shield and a plurality of subunits. The main conductive shield may be located on an inner side of the insulative main jacket so as to be at least partially surrounded by the insulative main jacket. Each subunit includes a twisted pair of insulated conductors, a conductive subunit shield and a subunit insulative layer. The conductive subunit shield may at least partially surround the twisted pair of insulated conductors. The subunit insulative layer may be located on an outer side of the conductive subunit shield to at least partially surround the conductive subunit shield and the twisted pair of insulated conductors.

“A cross filler for arrangement within a LAN cable has a plurality of twisted pair conductors. The cross filler has a body and a plurality of radially extending arms from a center point. Each of the arms has a plurality of spaced apart notches cut into the arms, the notches spaced apart along the length of the arms. Each of the notches are dimensioned allowing bending of the LAN cable without physical breakdown of the cross filler.”

Twisted pair cables incorporated separators with cooling channels are described. A cable may include a plurality of twisted pairs of individually insulated electrical conductors, and a separator extending lengthwise along a longitudinal length of the cable may be positioned between at least two of the plurality of twisted pairs. The separator may include a flexible body configured to maintain the at least two pairs in a predetermined configuration. A first channel extending lengthwise may define a longitudinal cavity through the separator, and at least one second channel may extend from the first channel through the flexible body to an outer surface of the separator. Additionally, the cable may include a jacket formed around the plurality of twisted pairs and the separator.

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. The separator may include a longitudinally extending spine positioned between the plurality of twisted pairs, and one or more respective projections extending from the spine at each of a plurality of longitudinally spaced locations. Each projection at a given spaced location may extend between a respective set of adjacent twisted pairs. Additionally, a respective longitudinal gap of at least approximately twenty centimeters may be present between each adjacent pair of longitudinally spaced locations.
