NOVELTY - The utility model relates to cable technology field of high speed data transmission, especially relates to an anti-interference data cable covered with high flame-retardant sheath. the cable comprises a cable core, and a functional layer covered outside the cable core, the cable core comprises a supporting frame, and a plurality of single wires located and twisted at the periphery of the supporting frame; the functional layer comprises a locating layer directly covered on the periphery of the cable core, and sequentially graphene shielding layer coated outside the locating layer, a metal shielding layer and a sheath. The cable product has stable performance, reduces the signal between the coupling, can satisfy ultra-five types of crosstalk requirement, and saves the twisting step, so that the process is simpler.
