Problems solved by technology

[0002] The rapid development of information technology requires a network with faster speed and larger capacity, and the existing six types of cables widely used in the wiring market can no longer meet the transmission rate of each pair of four pairs of cables up to 2.5Gb / s 100m distance transmission, the bandwidth is only 250MHz; the minimum bandwidth requirement of 10G technology is 500MHz, and at such a high frequency, it is difficult to solve the problem of noise interference between line groups during wiring through simple digital signal processing technology Therefore, it is necessary to design an enhanced category six digital communication pair cable to solve the external crosstalk and ensure the performance at high frequencies

Embodiment Construction

[0013] As shown in the figure, the product is an unshielded layer data communication symmetrical cable, which consists of a cross-shaped filler 1 and four pairs of super Category 6 network twisted pairs 21, 22, 23, 24 respectively arranged in the recesses of the filler 1. Composition, an inner sheath 3 is arranged on the outside of the above structure, the inner circumference 31 of the inner sheath 3 is a smooth circumferential surface, and the outer circumference 32 forms a wavy, zigzag, trapezoidal or square protrusion. The inner sheath 3 is surrounded by an outer sheath 4.

[0014] Coupled with two layers of sheaths, a new type of digital communication twisted pair cable for 10G Ethernet is formed.

[0015] In the cable with the above structure, take the twisted pair 21 as an example. The twisted pair 21 is composed of two core wires. Each core wire is composed of a conductor 2111, 2121 and is respectively covered with the conductor 2111, 2121. The insulating layer 2112, 2122 o...

Abstract

The invention discloses a non-shielded symmetry data cable used in 10G Ethernet, comprising a plurality of coupled twisted lines, stuff, an inner protective sleeve, and an outer protective sleeve, wherein the outer surface of the inner sleeve is provided with a plurality of protrusions. The invention uses double layers of protective sleeves to resolve the inter-group interference problem between nearby cables of non-shielded wire system at high-speed transmission in 10G Ethernet, and uses special waveform inner protective sleeve or the like to increase the distance between nearby cable groups of beam bonded communication cables, as well as meet the wire flexible and easy installment demands, while The invention can save the material of protective sleeve, with high benefits and practicality. The invention uses special waveform structure of the double layers of protective sleeves to effectively restrain inter-group interference.

Description

Technical field [0001] The invention relates to a data cable, in particular to an unshielded digital communication symmetrical data cable for 10G Ethernet. Background technique [0002] The rapid development of information technology requires a faster and larger capacity network to carry, but the existing six types of cables widely used in the cabling market can no longer meet the transmission rate of each pair of cables on the four pairs of cables to reach 2.5Gb / s 100m distance transmission, the bandwidth is only 250MHz; the minimum bandwidth required for using 10G technology is 500MHz, and at such high frequencies, it is difficult to solve the problem of noise interference between wire groups during wiring by simple digital signal processing techniques. To solve the problem, it is necessary to design an enhanced Category 6 digital communication twisted pair cable to solve the external crosstalk and ensure the performance under high frequency. Summary of the invention [0003]...
