Problems solved by technology

[0004] In the prior art, two separate insulated conductors (such as solid silver-plated copper) arranged in a parallel relationship are provided, and a shielding structure is provided outside. In order to improve the shielding effect, the prior art usually uses a composite of aluminum foil + aluminum wire braiding Shielding structure, but this also increases the attenuation of the electrical signal, resulting in a low cut-off frequency (suck out)

Abstract

The invention relates to a high-speed communication cable and belongs to the technical field of high-speed data transmission. The high-speed communication cable of the present invention includes a pair of conductors arranged side by side in parallel, the periphery of each conductor is coated or coated with an insulating material, and the periphery of the insulating material is sequentially coated with a composite shielding film and an outer sheath; the composite shielding film It includes a plastic substrate and aluminum layers deposited on the upper and lower surfaces of the plastic substrate by sputtering. The high-speed communication cable of the invention not only has low delay difference, but also has high cut-off frequency and excellent shielding attenuation performance.

Description

Technical field [0001] The present invention relates to a technical field of high-speed data transmission, more particularly, the present invention relates to a high-speed communication cable. Background [0002] Communication cable is the transmission of telephone, telegraph, fax files, television and radio programs, data and other electrical signals of the cable, which has a large communication capacity, high transmission stability, good confidentiality, less affected by natural conditions and external interference and other advantages, providing a reliable data transmission medium. As we all know, communication cables can be used for near-range audio communication and long-distance high-frequency carrier and digital communication and signal transmission. [0003] With the development of 5G technology, cloud technology and the Internet of Things, high-speed communication cables that can transmit data at faster speeds are required. As we all know, optical fiber communication cab...
