Description of drawings
Below, with reference to accompanying drawing, for those skilled in the art that, from detailed description of the present invention, above-mentioned and other purposes of the present invention, feature and advantage will be apparent.
Fig. 1 is the generalized section of cable of the present invention.
Embodiment
As shown in drawings, this product is non-screen data communication symmetrical cable, it surpasses six class network twisted pair wires 21,22,23,24 by cross filler 1 and four couple of being arranged at filler 1 recess respectively and forms, one inner sheath 3 is around in the outside of said structure, interior all 31 of this inner sheath 3 is smooth periphery, periphery 32 forms has waveform, zigzag, trapezoidal or foursquare projection, is provided with oversheath 4 in the outer peripheral of inner sheath 3.
Add two-layer sheath composition, so just formed a novel digital communication paired cable cable that is used for the 10G Ethernet.
In the cable of said structure, with twisted pair wire 21 is example, this twisted pair wire 21 is made up of two heart yearns, wherein every heart yearn is made up of conductor 2111,2121 and the insulating barrier 2112,2122 that is coated on respectively on these conductor 2111,2121 outer surfaces, and two conductors the 2111, the 2121st wherein are that the solid conductor of 0.60mm is made by nominal diameter; The insulating barrier 2112,2122 of heart yearn is made by high density polyethylene (HDPE) (HDPE) material, and insulating barrier 2112,2122 thickness are 0.19 ± 0.02mm; Two heart yearns of twisted pair wire 21 are the twisting shape, and four pairs of lines all adopt the back twist technology of (20～60) %, and the middle cross that adds is filled during four pairs of line strandings, and cross is filled by high density polyethylene (HDPE) (HDPE) material, width is about 5.4 ± 0.2mm, and thickness is 0.5 ± 0.15mm.
The present invention is broken through on structure, on traditional high-speed digital communication paired cable basis, improved the structure of restrictive coating, the adjacent lines group crosstalks when having suppressed wiring effectively, can non-shielding multiple twin on configuration 10G Ethernet, and 100m. that transmission range is reached require in the structured wiring and this structure are lower than shielding twisted pair wire and the easier installation of optical cable wiring system and cost, be a Eco-power cable. both satisfied EIA/telecommunications industry association EIA/TIA-568B.2-10 draft mechanical performance and the requirement of electric property, also satisfy the desired fire protecting performance in American insurance merchant laboratory (UL), have easy to use. the advantage of being convenient to lay.
In addition, high-speed digital communication paired cable of the present invention has 5 important unit for electrical property parameters: cross-talk etc. between impedance, decay, return loss, cross-talk (in the group), group has taken into full account five equilibrium when design.
Wherein, impedance is a parameter the most basic in the electric property, and it is by conductor lines footpath, two conductor centre-to-centre spacing, these three the parameter decisions of insulative dielectric constant, and not matching of any impedance all can cause the error of final acknowledge(ment) signal.We the time have taken into full account the influence of these three factors in design, and the conductor lines footpath is big, and low cut can be got well, but cost raises, and finish line footpath is bigger than normal; The conductor lines little decay meeting in footpath is influenced.Considering when producing the different and tension force of pitch, inconsistent can to produce each line different and influence impedance to two conductor centre-to-centre spacing, go out different insulated wire footpaths according to different multiple twin pitch design, the right resistance value of every line is controlled at about 100 ± 15Ohm behind the assurance finished product.
Decay is divided into conductor decay and diectric attenuation two parts, and the conductor decay is relevant with resistance, so we adopt oxygen-free copper or hypoxemia copper product, makes resistance reach minimum; Insulating material is selected high density polyethylene (HDPE) (HDPE) material for use, all is the smaller material of dielectric constant and dielectric loss angle.
Return loss is subjected to the influence of input impedance, because and load impedance do not match or make in the inhomogeneous point in cycle, and the reflection that produces signal, input impedance is fluctuateed up and down at characteristic impedance value, the energy of reflection aggravates along with the increase of frequency, even can produce the sudden change significantly of return loss.Adopted the pre-back twist technology of pair twist in the design, eliminated the influence of periodic inconsistent generation, improved the stability of input impedance, thereby optimized return loss input impedance.
The design of cross-talk is to be based upon on the pitch of original six class lines in the group, the pitch design of original six class lines is supported the frequency of 250MHz only, and existing 10G wire rod requires to possess crosstalking above 500MHz, so reduced the pair twist pitch during design, increased the thickness of cross packing, and used the statistical method of Six Sigma experimental design to select best pitch, thereby satisfied the requirement of crosstalking in the group, real system can satisfy the qualified index of crosstalking of 1000MHz.
One of performance that high-speed digital communication paired cable of the present invention is superior is embodied on the anti-external world crosstalks.When traditional non-shielding six class digital communication paired cable designs can't solve frequency and extend to high frequency, the interference of adjacent lines group same pitch line centering transmission signals, the structure (ellipse) of skeleton filled in the cable cross or the method for the interior more filling of line group solves this puzzlement so the many employings of more in the world renowned company change into, the former has stronger convincingness in theory, difficulty is bigger during actual production, and wire rod presents irregular circle, and the hidden danger of many unknowns is arranged; The latter has increased the control point because of having dosed too many filling when actual production, performance also is difficult to guarantee stable.The zigzag inner sheath that our company adopts and the duplex sheath structure of oversheath seem simply, but crosstalk between solution group effectively, and handling ease, save material, be a getting twice the result with half the effort. Eco-power new product.
The front provides the description to preferred embodiment, so that any technical staff in this area can use or utilize the present invention.Various modifications to these embodiment are conspicuous to those skilled in the art, can be applied to other embodiment to total principle described here and not use creativeness.Thereby, the embodiment shown in the present invention will be not limited to here, and the wide region of principle that should disclose and new feature according to meeting here.
