High-speed data cable

Abstract

The invention discloses a high speed data cable. It includes sheath and many pairs of cable. Each pair of wire is formed by two insulation cores wires. A separation rib is set in the sheath. And the separation rib is foam structure. The twin is symmetrically set at the both sides of the separation rib. The foam structure is that some dry bubble are uniformly scattered in the section of the separation rib. The surface of the separation rib is concavo convex. The advantages are stable and reliable structure flexible, and easy to bend.

Description

technical field [0001] The invention relates to a data transmission cable, in particular to a line group data cable for transmitting high-frequency digital signals. Background technique [0002] With the rapid development of digital technology, computers are not only widely used in various industrial facilities, but also widely popularized in various offices and even residential buildings. The continuous expansion and extension of computer networks, as well as the sharp increase in the amount of transmitted information, on the one hand, have increased the amount of data cables used for network deployment by a large margin; on the other hand, data cables have been required to have higher transmission speeds and wider transmission bandwidth to achieve fast and accurate transmission of information. Its transmission speed range has also developed from 10Mbps to 1000Mbps, and it is foreseeable that due to the increasing traffic, the network speed will greatly exceed 1000Mbps in ...

Problems solved by technology

[0010] In addition, due to the size gap between the outer diameter of the cross frame and the inner diameter of the cable jacket, the positioning performance of the cross frame is insufficient, and it is easy to cause radial displacement and movement of the frame in the outer sheath, resulting in the size of the space occupied by each pair of wire groups. One or random variation, causing additional extrusion and drafting of the wire group

These factors that cause small changes in geometric position or shape will cause a sharp decline in the performance of high-speed data cables

[0011] Also because the cross frame adopts a solid structure, this solid frame has a high dielectric constant, which is not conducive to the reduction of the capacitance value between the paired wire groups, and also restricts the further improvement of the electrical properties such as the impedance and attenuation of the paired wire group
