High frequency data communications cable

The utility model relates to a high frequency data communication cable which belongs to the technical field of network communication. The utility model comprises a plurality of line pairs 2 respectively formed by line cores 2a, 2b, aluminum foil layers 1 wrapped around each line pair 2, a wrapping belt 3 used for bundling all the line pairs 2 wrapped by the aluminum foil layers 1 together to form a cable core, a knitting layer 4 positioned outside the wrapping belt 3, an isolating layer 5 and an exterior protection layer 6. The line cores 2a, 2b are close to each other in parallel and the exterior parts of the line cores 2a, 2b are additionally provided with self-adhering layers 8 connected with the aluminum foil layers 1. The utility model has the advantages that the line cores 2a, 2b forming the line pairs 2 adopt a parallel structure, are provided with the self-adhering layers 8 and are wrapped and fixed by the aluminum foil layers 1. The line cores 2a, 2b can not displace and the dislocation can be prevented without the need of mutually twisting the line cores 2a, 2b, so that the technology can be shortened and simplified. The aluminum foil layers 1 can be excellently combined with the self-adhering layers 8 and do not cove during bending in the process of laying. The short circuit among the line pairs 2 is avoided. The entirety of the utility model embodies stable input impedance, low attenuation, delay inequality performance to interior and exterior, and crosstalk prevention interference.
