Abstract
The invention relates to a high-speed high-definition anti-interference communication cable, which comprises four high-frequency wire groups and a low-frequency wire group. An insulating sheath is wrapped on the outer layer of the high-frequency and low-frequency wire groups, and has a flat section. Two of the high-frequency wire groups are combined into a first large group, and the other two of the high-frequency wire groups are combined into a second large group. The first large group, the second large group and the low-frequency wire group are arranged at intervals in which an insulating material is filled. Each high-frequency wire group is a twisted pair formed by twisting two core wires. A shielding layer is wrapped on the outer layer of the twisted pair. The high-speed high-definition anti-interference network communication cable is flat, and has a relatively smaller thickness and a relatively higher bending property, and crosstalk influence among the wire groups is low when the cable is bent, so that transmission performance is improved, and the flat cable is more convenient to arrange; a space is saved; and a polyester tape layer and an aluminum foil layer are adopted as the shielding layers, so that shielding performance and anti-interference performance are improved.
