Example Embodiment

[0013] The present invention will be further described below in conjunction with embodiments and drawings.

[0014] figure 1 It is a schematic cross-sectional structure diagram of a broadband data communication cable.

[0015] There are two pairs, four pairs, eight pairs, sixteen pairs, and even more pairs of twisted pair 1 of broadband data communication cables. The twisted pair 1 is formed by twisting two insulated cores 2 at a certain pitch. The insulated cores 2 are formed by extruding a high-density polyolefin insulation layer 22 on a conductor 21 made of copper wire. The twisted pair 1 is wrapped with 0.1mm thick aluminum foil as the first metal shielding layer 3. The cable is composed of multiple pairs of twisted pair 1 wrapped with the first metal shielding layer 3 and the aramid water blocking yarn 9 twisted. Core 4, double-layer 0.05mm thick polyester tape is used to wrap around the cable core 4 as the wrapping layer 5, and the 0.2mm thick double-sided Mylar aluminum fo...

Abstract

The invention discloses a broadband data communication cable, belonging to the technical field of cables. The broadband data communication cable comprises a cable core and a sheath layer; the cable core is composed of double twisted pairs, which are formed by multiple pairs of insulation wire cores in a twisting manner; each insulation wire core is formed by a polyolefin insulation layer wrapped on a conductor in an extruded manner; the conductor is a copper conductor; a first metal shielding layer is lapped on the double twisted pairs; a water-blocking filler is filled in the cable core; and a belting layer, a second metal shielding layer and the sheath layer are sequentially arranged outside the cable core. The broadband data communication cable disclosed by the invention is reasonable in structural design; the separated shielding and overall shielding structural design is adopted; furthermore, a grounding conductor wire for introducing current into the ground is additionally arranged outside the shielding layer; due to the design, the anti-interference performance is greatly increased; excellent water-blocking performance, characteristic impedance, attenuation and loop loss indexes can be obtained; the transmission frequency is relatively high; and simultaneously, an aluminium strip is replaced by an aluminium foil, such that the better bending property is realized.

Description

technical field [0001] The invention belongs to the technical field of communication cables, in particular to a broadband data communication cable used for high-speed transmission of data signals such as super-large-capacity audio, video, and image. Background technique [0002] With the rapid development of digital life, the requirements for data communication cables are getting higher and higher, requiring higher transmission bandwidth, capacity, speed and distance. [0003] For broadband data communication cables, signal delay difference, attenuation and loop loss have always been important indicators for measuring high-speed data cables. Although the highest transmission frequency of products on the market can reach 30MHZ or even 100MHZ. However, it has been found through practice that if the capacity of the data cable is increased or the transmission distance is lengthened, it will cause signal attenuation and loop loss, and cannot show a satisfactory transmission effec...
