Abstract
The utility model relates to a CAT6A unshielded data cable comprising twisted pairs, a crossed skeleton, and an outer sheath wrapping the twisted pair and the crossed skeleton, wherein the crossed skeleton is filled among the twisted pairs and has edges with unequal lengths. Crossbeams used for separating the twisted pairs from the outer sheath are vertically arranged on the edges of the cross skeleton. The CAT6A unshielded data cable effectively decreases electromagnetic coupling interference in the cable and external crosstalk so that normal transmission can be guaranteed when signal transmission frequency reaches 500 MHz in the case of concentrated wire distribution.
Description
Technical field
The utility model relates to field of information transmission, is specifically related to the non-shadow data cable of a kind of CAT6A.
Background technology
Current 5 classes and 6 class data cables are widely used in Ethernet 10/100/1000BASE-T comprehensive wiring system, even but such demand that still can not meet data communication, and along with the promulgation of IEEE802.3an10GBASE-T standard and ANSI/TIA-568-C standard, 10G wiring technique is considered and adopts by increasing enterprise.But because the requirement of 10G10GBASE-T system is too high, also be very harsh to the requirement of the performance of cable own, not only to cable self line between interference have requirement, interference between cable and cable is also had to certain requirement, cable must be by the AXT test of the strictest 6+1 simultaneously.
And the data cable of common six classes in the market can not be applied in 10GBASE-T system, its main cause is the test frequency that the electric properties such as its AXT and return loss can only meet 250MHZ.Once frequency exceedes 250MHZ, the performance index of AXT and return loss will sharply decline, and signal-to-noise ratio degradation causes the interference between signal to strengthen, can not normal transmission signal.Common shielding or non-shielding six classes, for 10GBASE-T system, system can not be brought into play its function, meeting because crosstalk or the loss of packet and cause the data can not normal transmission, system is unstable, affects the quality level of whole network.
High-frequency data cable in the time of signal transmission, line between because signal coupling effect produces interference, simultaneously between cable, also can produce interference, the impact that the signal frequency of transmission is got over high interference is just approximately large, in the time that frequency reaches 500MHZ, responsive especially.For solve cable inner wire between interference and cable between interference problem, the non-shadow data cable of a kind of CAT6A is provided in Chinese utility model patent CN202042277U, this patent is by changing the big or small method of twisted pair wire to pitch in data cable, and then the performance of improvement interference, although the size that changes pitch can change the performance of interference, but in the time that pitch changes to a certain degree, also can have influence on other performances in cable, as return loss, decay, impedance etc.
Utility model content
The utility model provides the non-shadow data cable of a kind of CAT6A, by increasing the distance between line pair, and then increases insulation property, reduces the coupling effect between line pair, reaches to promote and improves the performance that disturb inside and outside.
The non-shadow data cable of a kind of CAT6A, comprises twisted pair wire, is filled in the not isometric crossing skeleton in edge between twisted pair wire and is wrapped in twisted pair wire and the outer field oversheath of crossing skeleton; The edge of described crossing skeleton is vertically installed with the crossbeam for separating described twisted pair wire and oversheath.
The cross section of above-mentioned crossing skeleton is " ten " word, uses polyethylene foamed material to make;
Preferably, the quantity of twisted pair wire is 4 pairs, and every pair of twisted pair wire is by stranded the forming of a pair of copper single line;
Wherein, every pair of copper single line comprises again copper core and is coated on the polyethylene layer outside copper core.
Further, the non-shadow data cable of above-mentioned CAT6A also comprise setting in the inner tear rope, for strip off oversheath.
Further, the external surface shape of oversheath is twisted shape, and cross section is oval, can greatly increase distance and the insulation property of cable.
When four pairs of twisted pair wires are together with crossing skeleton when stranding, crossing skeleton is four pairs of effective intervals of twisted pair wire, and during crossing skeleton marginal portion wraps in four pairs of twisted pair wires firmly.The electromagnetic coupled that can greatly weaken like this between line pair is disturbed, and can to make to extrude the cross-section of cable after oversheath be ellipticity to this crossing skeleton simultaneously.
The beneficial effects of the utility model:
1, effectively weakened the magnetic-coupled interference of cable internal electrical and AXT, though like this in the situation that of concentric wiring signal transmission frequencies reach 500MHZ and also can ensure to transmit normally;
2, this cable does not only change the production procedure of common six type unshielded data, does not reduce its production efficiency yet, but cable but reaches the requirement of 6+1 (accompanying drawing 2) AXT test completely, has greatly promoted the transmission rate of data cable;
3, this cable can be applied in the system of 10GBASE-T, and meets the requirement of the standard of ANSI/TIA-568-C, meets market user's demand, has competitive advantage, and profit is considerable.
Brief description of the drawings
Fig. 1 is the utility model data cable structural representation;
Fig. 2 is that the utility model carries out the 6+1 AXT schematic diagram in when test.
Embodiment
As shown in Figure 1, the non-shadow data cable 100 of CAT6A of the present utility model, comprises twisted pair wire 103, is filled in the crossing skeleton 104 between twisted pair wire 103 and is wrapped in twisted pair wire 103 and the outer field oversheath 106 of crossing skeleton 104; The edge of crossing skeleton is vertically installed with the crossbeam 107 for separating twisted pair wire and oversheath.
As shown in Figure 1, wherein the cross section of crossing skeleton 104 is " ten " word, uses polyethylene foamed material to make; In the present embodiment, the quantity of twisted pair wire 103 is 4 pairs, and every pair of twisted pair wire 103 is by stranded the forming of a pair of copper single line;
