Abstract

The invention discloses a shielding high-speed enhanced CAT 7 type data communication cable which comprises eight copper leads and a cross skeleton. A sheath layer wraps a tinned copper wire braided layer. The sheath layer comprises 100 parts by weight of 1,3-butadiene, styrene, ethane-vinyl acetate copolymer, ethane-vinyl acetate copolymer grafted maleic anhydride copolymer, siloxane, vapor-phase-method white carbon black, cooper powder, microcrystalline wax, titanium white, 4,4'-bis(alpha,alpha-dimethylbenzyl)diphenylamine, dicumyl peroxide, triallyl cyanurate and dilauryl thiodipropionate. The pitches of first, second, third and fourth twisted pairs are 15.2, 13.7, 14.4 and 12.9 mm respectively. The shielding high-speed enhanced CAT 7 type data communication cable improves reflection and absorption of high-frequency electromagnetic waves, reduces crosstalk and signal attenuation, broadens the bandwidth of adsorption frequency, and enhances the stability of product performance.

Description

technical field [0001] The invention relates to a super-category 7 data communication cable, in particular to a shielded high-speed super-category 7 data communication cable. Background technique [0002] The large-scale application of digital cables and the rapid exponential growth of information technology have put forward higher requirements for information transmission media, and the requirements for data transmission lines have also become higher and higher. Traditional data lines cannot fully meet the high-resolution requirements of digital imaging technology. , high transmission rate, high color depth image and digital audio requirements, how to improve the reflection and absorption of high-frequency electromagnetic waves, improve crosstalk and signal attenuation, expand the bandwidth of absorption frequency and improve the stability of product performance, become the direction of efforts of those skilled in the art. Contents of the invention [0003] The purpose o...
