Abstract: A cabling media which is suitable for high performance data transmission includes a plurality of insulated metallic conductor-pairs, each pair including two plastic insulated metallic conductors which are twisted together. More specifically, the introduction of a periodic rotation along the length of each insulated conductor essentially acts to cancel out a large number of the adverse effects which may result due to a lack of conductor concentricity and/or dielectric eccentricity.

Abstract: A local area network cable capable of high speed signal transmission has a plurality of twisted pairs of conductors enclosed within a jacket. Each of the twisted pairs has a different twist frequency than any of the other pairs, and at least one of the pairs has a direction of twist that is different from the other twisted pairs, that is, it may have a right hand twist where the other pairs have a left hand twist. In a four pair cable, two of the pairs, of different twist frequency, have imparted thereto a right hand twist, and two of the pairs have a left hand twist.

Abstract: A cabling media which is suitable for high performance data transmission includes a plurality of metallic conductors-pairs, each pair including two plastic insulated metallic conductors which are twisted together. The present invention describes how the selection and incorporation of metallic conductors having different diameters within a single communication cable can significantly enhance the operational performance of the cable. More specifically, given a first conductor-pair having a certain conductor diameter and twist length, and at least one other conductor-pair with a different twist length, the present invention purposely selects metallic conductors for this other conductor-pair with a different diameter than that of the first conductor-pair so as to ensure that the insertion loss exhibited by the additional conductor-pair is essentially equal to the insertion loss exhibited by the first conductor-pair.

Abstract: A cabling media which is suitable for data transmission with relatively low crosstalk includes a plurality of metallic conductors-pairs, each pair including two plastic insulated metallic conductors which are twisted together. The characterization of the twisting is important and relates to parameters such as twist length as well as core strand length/lay. More specifically, particular combinations of twist lengths and core strand length/lay are purposely selected for each insulated pair of the cable in order to achieve performance capabilities that significantly surpass those required under TIA/EIA-568A. In one particular embodiment of this invention, a cable comprises as its transmission media, four twisted pair of individually insulated conductors with each of the insulated conductors including a metallic conductor and an insulation cover which encloses the metallic conductor.
