Abstract
The utility model discloses a CAT6A data shielding cable. The CAT6A data shielding cable comprises twisted pairs (103) and an outer sheath (110) outside the twisted pair (103), wherein a polyester tape (107) is further arranged between the twisted pair (103) and the outer sheath (110), a filler (104) with a cross-shaped section is arranged at the center of the cable and divides the four twisted pairs (103) and fixes the twisted pairs (103) by the polyester tape (107), a copper core (101) of one of the twisted pairs (103) is coated by an insulating layer (102) made from foam polyethylene; as physical foam technique is adopted, crosstalk and time delay property can be effectively ensured only by designing reasonable pitch without increasing of both twisted pair interval and cable diameter.
Description
Technical field
The utility model relates to a kind of data cable, particularly a kind of CAT6A shadow data cable.
Background technology
Present 5 classes, 6 class data cables are widely used in the Ethernet 10/100/1000 BASE-T comprehensive wiring system, even but appoint the demand that does not so satisfy data communication like this, and along with among the TIA-EIA-568C to the promulgation of CAT6A standard, CAT6A shadow data cable formally becomes the leading role in the 10GBASE-T wiring system.But, also be unusual harshness to the performance requirement of cable itself because the requirement of 10G10GBASE-T system is too high.
A lot of 6A class data cables in the market can not satisfy the requirement of the regulation of CAT6A among the TIA-EIA-568C fully, even there are a lot of so-called CAT6A shadow data cables can satisfy simple 90m link test requirement, but but can not satisfy the requirement of network analyzer, crosstalk very unstable or delay inequality can not be by (standard-required be lower than 45ns) according to the 100m electric property of the regulation of CAT6A among the TIA-EIA-568C.
CAT6A shadow data cable is crosstalked unstable and delay inequality can not be passed through, and mainly is because after adding last layer and shielding, signal online to transmission the time leakage signal can on aluminium lamination, reflect, to line to causing interference once more.Once that the right pair twist pitch of twisted pair wire cooperates is unreasonable, will make a big impact to crosstalking.And delay inequality can not be passed through, and also is because the different great disparities of pitch size are very big, and the distance of the online centering transmission of signal is different, and forms a time difference, causes time delay excessive.
The application of 10base-T system is had higher requirement to the data cable of one of bearing medium of network, and for CAT6A shielded type cable product, and the most difficult is exactly control to crosstalk and delay inequality.Only overcome the problem of crosstalking and effectively to improve signal to noise ratio in the transmission line, to guarantee the reliability of data with delay inequality.From the angle of information security, consider the problem of the leakage of transmission signals again in addition, so the shielding of CAT6A product just seems most important.
The utility model content
Technical problem to be solved in the utility model provide a kind of in delay inequality, crosstalk aspect the CAT6A shadow data cable of superior performance.
Improving the direct way crosstalk is exactly that each factory designs satisfactory pair twist pitch according to the equipment performance of reality, the another one method be exactly increase line to the interval, slacken electromagnetic interference, promote the crosstalk performance of cable.
Because CAT6A shadow data cable itself is installed and the joint cost is very high, therefore in case increase line to the interval outside diameter of cable will become greatly, this can give the increasing of wiring difficulty, cost also can increase a lot.Therefore first-selected still with the way that changes the pair twist pitch, solve the problem of crosstalking with delay inequality.
Because kelvin effect and electromagnetic coupled are added the influence of shielding reflection, what need that the pair twist pitch tries one's best is little, and differing in twos between pitch needs the relative big performance of crosstalking of could guaranteeing like this, and this has just brought very big difficulty to design.In case the scope of minimum pitch and maximum pitch is extended, will make signal at the minimum pitch line to also just cause delay inequality not pass through with the time difference of transmission being strengthened at the maximum pitch line.Delay inequality is excessive, will cause the transmission course lost data packets, cause packet to wait in line after, thereby cause serious network blockage, influence the transmission quality of overall network.And if with the minimum pitch change greatly, can cause the generation of cross-interference issue again.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of CAT6A shadow data cable, comprise the oversheath that twisted pair wire and twisted pair wire are outer, also be provided with polyester belt between twisted pair wire and the oversheath, be provided with the filler of cross section in cable center for " ten " word, filler is separated four twisted pair wires, and by polyester belt twisted pair wire is fixed, and the copper core of a twisted pair wire in the described twisted pair wire is the insulating barrier coating of polyethylene foamed by material.
For shield electromagnetic interference, between described polyester belt and oversheath, also be provided with the shielding aluminium-plastic tape, in the application of system, can also prevent leakage signal, promoted complete network.
Static occurs through regular meeting on the screen of cable, derive smoothly in order to make the static on the cable, described shielding aluminium-plastic tape is provided with the percolation conductor.
The wherein a pair of employing foaming technique of CAT6A shadow data cable, the line footpath that does not need to increase the right interval of line and do not need to increase cable, only need design rational pitch and just can effectively guarantee to crosstalk and the delay inequality performance, and can effectively improve the stability of cable electrical performance by this technology.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The utility model adopts three-layer co-extruded foaming technique can effectively solve time delay and delay inequality technical barrier minimum a pair of pitch in four twisted pair wires.After the pitch foaming with minimum, make dielectric constant and electric capacity all diminish, can accelerate the propagation velocity of the online centering of signal like this, so both can enlarge the right pair twist pitch range of line, can promote the performance of delay inequality again.
Its structure as shown in drawings, CAT6A shadow data cable comprises the oversheath 110 outside twisted pair wire 103 and the twisted pair wire 103, also be provided with polyester belt 107 between twisted pair wire 103 and the oversheath 110, be provided with the filler 104 of cross section in cable center for " ten " word, filler 104 is separated four twisted pair wires 103, and by polyester belt 107 that twisted pair wire 103 is fixing, the copper core 101 of a twisted pair wire 103 in the described twisted pair wire 103 is insulating barrier 102 coatings of polyethylene foamed by material.Like this, the line footpath that does not just need to increase the right interval of line and do not need to increase cable guarantees to crosstalk and the delay inequality performance.Its excess-three bar twisted pair wire 103 adopts by stranded formation of a pair of copper single line, and the copper single line comprises copper core 101 and extrudes by plastic extruding machine that to be coated on outside the copper core 101 be real core polyethylene layer 105.
For shield electromagnetic interference, also be provided with shielding aluminium-plastic tape 109 between polyester belt 107 and the oversheath 110, can prevent leakage signal, promoted complete network.
For the static on the cable is derived smoothly, described shielding aluminium-plastic tape 109 is provided with percolation conductor 108.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection range of the present utility model.
