Problems solved by technology

[0004] In the prior art, two separately 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 composite of aluminum foil + aluminum wire braiding is usually used in the prior art 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 comprises a pair of conductors arranged side by side in parallel, the periphery of each conductor is wrapped or coated with an insulating material, and the periphery of each insulating material is sequentially coated with a composite shielding film and an outer sheath; the composite shielding film comprises a plastic substrate and aluminum layers sputtered and deposited on the upper surface and the lower surface of the plastic substrate. The high-speed communication cable has the advantages of low delay difference, high cut-off frequency and excellent shielding attenuation performance.

Description

technical field [0001] The present invention relates to the technical field of high-speed data transmission, and more specifically, the present invention relates to a high-speed communication cable. Background technique [0002] Communication cables are cables for transmitting telephone, telegraph, fax files, TV and radio programs, data and other electrical signals. They have the advantages of large communication capacity, high transmission stability, good confidentiality, and less affected by natural conditions and external interference. , providing a reliable data transmission medium. As we all know, communication cables can be used for short-distance 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 comm...
