Taking Starte unshielded twisted pair Cat6 network cable as an example, two single conductors in the line are twisted together to form a pair, and a high-density polyethylene cross-isolation bracket is arranged in the middle of the cable to distinguish four pairs of wires, and the four pairs of cores are respectively placed on the cross skeleton. In the four grooves, the balance performance of the pair is more stable, which can effectively prevent the performance degradation caused by the change of the twist between the pairs.
The cross skeleton at the center of twisted pairs Cat6 network cable rotates with the change of the length, and the four pairs of cores are stuck in the grooves of the skeleton to maintain the position of the four pairs cores. This structure is beneficial to reduce the pair between the pairs. Crosstalk improves the balance of the cable.
At the same time, the six-type twisted pair center cross isolation ensures NEXT performance and reasonable construction bend radius.
Of course, there is Cat6 network cables without cross skeletons that can eliminate crosstalk in the standard requirements. Therefore, it is not possible to judge whether there are Cat6 network cables with or without crosses. For example, some brands only have one character skeleton but still meet Cat6 network cable atandard and reach 4.8gbps.
