The invention discloses a data cable. The data cable comprises a framework body, four groups of twisted line pairs, solid rat repelling blocks, four coverage blocks, a waterproof layer and a sheath, wherein the framework body has four fan-shaped parts, an accommodating cavity is formed between two adjacent fan-shaped parts, installation grooves are formed in arc side walls of the fan-shaped parts, the four groups of twisted line pairs are respectively arranged in the corresponding accommodating cavities, the solid rat repelling blocks are arranged in the installation grooves, the four coverage plate respectively cover the corresponding accommodating cavities, the waterproof layer wraps the framework body and the coverage plates, and the sheath wraps the waterproof layer. By the data cable, the fan-shaped parts are effectively used for forming the installation grooves for arranging the solid rat repelling blocks, and the space utilization ratio can be effectively improved compared with an independently-arranged rat repelling layer; the opening of the accommodating cavities is relatively large, and the waterproof layer can be prevented from being embedded into the accommodating cavities by the arrangement of the coverage plate to affect the quality of the data line.
