Problems solved by technology

The original data cable has small data transmission capacity, slow speed, and low confidentiality, which cannot meet the requirements of large-scale comprehensive and high confidentiality. During use, there will be bad phenomena such as jamming, blocking, and signal interruption, and data will be easily leaked.

Abstract

The present invention discloses a high frequency data cable of 1200 MHz. The high frequency data cable of 1200 MHz comprises a cable core unit, and the cable core unit includes four shielding subunits; each shielding subunit includes a pair of stranded wires with stranding pitches, each pair of stranded wires with stranding pitches consisting of two insulated single lines with different colors and high foaming; a low smoke zero halogen flame retardant polyolefin outer sheath coats a cable core unit; the cable core unit and the low smoke zero halogen flame retardant polyolefin outer sheath coat a single-face plastic-coated aluminum foil shielding layer and a braided prismatic tinned wire shielding layer in turn from the inside out. Through adoption of a copper wire polishing technology and an insulated wire core back-twist technology, the return loss of cables caused during transmission is reduced; through adoption of insulated single lines with high foaming, the transmission loss of cables is reduced, and transmission rate is enhanced, so that the requirement of 1200MHz high frequency transmission is satisfied; and moreover, through adoption of the modes of wire pair shielding, the aluminum foil shielding and tinned wire braiding shielding and the unique shielding technological structure of each shielding layer, the signal quality is improved.

Description

technical field [0001] The invention relates to a cable, in particular to a data cable. Background technique [0002] With the rapid development of social economy, network information technology is widely used in every corner of society. The construction of large residential quarters, comprehensive office buildings, and teaching buildings requires a wider transmission frequency band, larger transmission data volume, and faster transmission speed. Data center cables meet the needs of high-speed, stable and safe transmission of digital, analog voice, image, multimedia and data signals. The original data cable has small data transmission capacity, slow speed, and low confidentiality, which cannot meet the requirements of large-scale comprehensive and high confidentiality. During use, there will be bad phenomena such as jamming, blocking, and signal interruption, and data will be easily leaked. . The present application is an improvement of the invention based on the above-men...
