Abstract: A cable includes a jacket surrounding a cable core. The cable core includes four twisted pairs. An S-shaped separator separates two of the twisted pairs from the other two twisted pairs. The S-Shaped separator may be formed with two layers or three layers, wherein at least one layer is conductive. In alternative embodiments, one or both ends of the S-shaped separator make electrical contact to mid-portions of the separator to create one or two shielding cambers within the cable.

Abstract: A method for forming a cabling media includes providing a wire pair including first and second conductor members. Each of the first and second conductor members includes a respective conductor and a respective insulation cover surrounding the conductor thereof. The first and second conductor members are twisted about one another to form a twisted wire pair having a twist length that purposefully varies along a length of the twisted wire pair. The method may include: imparting a purposefully varied pretwist to the wire pair using a wire pair twist modulator; and imparting additional twist to the wire pair using a wire pair twisting device downstream of the wire pair twist modulator.

Abstract: A cable includes a plurality of twisted wire pairs housed inside an inner jacket, a shielding layer, and an outer jacket. Each of the twisted wire pairs has a respective twist length, defined as a distance wherein the wires of the twisted wire pair twist about each other one complete revolution. At least two of the respective twist lengths purposefully vary along a length of the cable. In one embodiment, the cable includes four twisted wire pairs, each with its twist length purposefully varying along the length of the cable. The twisted wire pairs may have a pair separator located there between. The pair separator may also twist, and may twist in a direction opposite to a twist direction of the twisted wire pairs. The cable is designed to surpass the requirements of CAT 6 and CAT 6A cabling, and demonstrates no alien crosstalk and low internal crosstalk characteristics even at data bit rates of 10 Gbit/sec and beyond.

In a further embodiment, the core strand length is purposefully varied along the length of the cabling media. The cabling media can be designed to meet the requirements of CAT 5, CAT 5e or CAT 6 cabling, and demonstrates low alien and internal crosstalk characteristics even at data bit rates of 10 Gbit/sec.

Abstract: There is disclosed a communications cable having a cable jacket and a first pair of twisted wires disposed within the jacket, each wire thereof having a conductor surrounded by a first insulating material. A second twisted pair of wires is disposed within the jacket and has a twist lay length different from that of the first twisted pair. Each wire of the second twisted pair has a conductor surrounded by an insulating material. The insulating material of the first twisted pair differs in a physical property from the insulating material of the second twisted pair, the physical property of the insulating material of the second pair being correlated with the physical property of the insulating material of the first twisted pair and with differences in twist lay length of the first and second twisted pairs so that the phase delay of the twisted pairs is matched. There is also provided a communications cable having more than two twisted pairs.
