摘要:
A discontinuous shielding tape comprises a first tape Iayer (10) having a first width and a metallic layer (12) disposed on said first tape layer having a second width, wherein said second width of said metallic layer is narrower than said first width of said first tape layer so as to leave at least two metallic free strips (14A, 14B) running the longitudinal length of said first tape layer, one on either side of said metal layer, wherein said metallic layer is scored only within said second width of said metal layer with resultant discrete metallic elements (16) such than when said first tape layer is stretched, said discrete metallic elements are separated each by a gap (22) creating said discontinuous shielding tape, where said two metallic free strips are configured to maintain integrity of said first tape layer.
摘要:
A cross filler for arrangement within a LAN cable has a plurality of twisted pair conductors (12). The filler has a body (21) and a plurality of radially extending arms (20), where each of the arms has a plurality of alternating supports and cavities along the surface of the arms. At least one of the radially extending arms is disposed within the LAN cable between at least two of the twisted pairs of the plurality of twisted pairs. The at least one of the radially extending arms is dimensioned such that when the cross filler is positioned with the cable, the at least two of the twisted pairs of the plurality of twisted pairs, on either side of the radially extending arm therebetween, rests on at least one of the supports on the radially extending arm.

The present invention relates to a cable, comprising: a first twisted pair of insulated conductors, said first twisted pair having a first lay length; a second twisted pair of insulated conductors, said second twisted pair having a second lay length, wherein said second lay length is longer than said first lay length; at least one jacket covering said pairs, wherein an additive is added to the insulation of the conductors of said second twisted pair so that the dielectric constant of the insulation of the conductors of said second twisted pair is raised relative to the dielectric constant of the insulation of the conductors of said first twisted pair resulting in a reduced skew between said first and second twisted pairs.
