The invention belongs to the technical field of communication cables, and relates to a high-strength digital communication cable. Two leads formed by wrapping solid copper conductors with polyethylene insulation layers are stranded to form a core wire group, 1-8 pairs of core wire groups are stranded and then lapped with wrapping tape layers to form a cable core with a circular cross section, gaps among the stranded core wire groups and the wrapping tape layers are filled with fillers, and a longitudinal wrapping layer, a braided shielding layer, an inner protective layer, an armor layer and an outer protective layer sequentially wrap the outside of the cable core from inside to outside to form the high-strength digital communication cable. Aramid fibers serve as the fillers, the 'S'-shaped steel screw interlocking armor layer is used, the composite outer protective layer comprises a polyurethane elastomer sheath, talcum powder and an irradiation crosslinking polyvinyl chloride sheath, so that the cable has high tensile strength, compressive capacity and good softening property, and high strength of the digital communication cable is realized. The high-strength digital communication cable is applicable to network cabling of protective environments which are easily trod and squeezed and free from pipelines, slots and the like.
