Definitions
- the invention relates to a data cable for high-speed data transmission with at least one wire pair of two longitudinally extending wires which are paired to form a pair shield in pairs of a screen, wherein between the screen and the pair a non-conductive intermediate film as additional film order the wire pair is spun.
- a data cable is offered at the time of filing by the applicant under the trade name "Paralink 23.”
- Such data cables are used in particular for the high-speed transmission of signals between computers, for example in data centers.
- a respective core here consists of the actual conductor, such as a solid conductor wire or a stranded wire, which is surrounded in each case by an insulation.
- the wire pair of a respective data line is surrounded by the (pair) shielding.
- the data cables typically have a plurality of such screened wire pairs, which form a line core and which are surrounded by a common outer screen and a common cable sheath.
- Such data cables are used for high-speed data connections and are designed for data rates of greater than 10 Gbit / s at a transmission frequency greater than 14 GHz.
- the outer screen is important for the electromagnetic compatibility (EMC) as well as for the electromagnetic interference (EMI) with the environment. No signals are transmitted via the outer screen.
- EMC electromagnetic compatibility
- EMI electromagnetic interference
- the respective pair screen determines the symmetry and the signal characteristics of a respective pair Wire pair. In this case, a high symmetry of the pair screen is important for undisturbed data transmission.
- Such data cables are typically so-called symmetrical data lines, in which the signal is transmitted via one wire and the inverted signal is transmitted via the other wire.
- the differential signal component between these two signals is evaluated so that external effects that have an effect on both signals are eliminated.
- Such data cables are often connected pre-assembled to plugs.
- the connectors are often designed as a so-called small-form-pluggable connector, short SFP connector.
- SFP +, CXP or QSFP connector There are different variants, for example, so-called SFP +, CXP or QSFP connector.
- These plugs have special plug housings, as can be seen, for example, from WO 201 1 072 869 A1 or WO 201 1 089 003 A1.
- Alternatively, a direct so-called back-plane connection without plug is possible.
- the pair shield of a respective pair of wires is - as can be seen for example from EP 2,112,669 A2 - often formed as a longitudinally folded screen.
- the shielding film is therefore folded in a longitudinal direction of the cable running around the pair of wires, wherein the opposite outer side regions of the shielding film overlap in a longitudinally extending overlapping region.
- a dielectric intermediate film made of plastic, in particular a PET film is spun between the screen film and the wire pair.
- the shielding foil used for the shielding is a multilayered shield of at least one conductive (metal) layer and an insulating carrier layer.
- a conductive layer an aluminum layer is usually used, and as the insulating base layer, a PET film is used.
- the PET film is formed as a carrier on which a metallic coating is applied to form the conductive layer.
- the screen foil is often preferably attached as a longitudinally folded screen foil.
- a signal cable for a high-frequency signal transmission in which the signal conductor is designed as a stranded conductor with a varying lay length.
- the signal cable furthermore has a shielding braid, with individual braid strands of the shielding braid being wound with a varying lay length here as well.
- DE 103 15 609 A1 discloses a data cable for high-frequency data transmission, in which a pair of wires is surrounded by a pair shield formed as a screen film. In addition, an intermediate foil is spun around the pair of wires.
- US 2014/0124236 A1 discloses a further high-speed data cable in which a screen foil provided as a pair shield is spun around the pair of wires with a varying lay length.
- the object of the invention is to specify a high-speed data cable with good transmission properties even at high transmission rates and high transmission frequencies.
- a data cable for high-speed data transmissions with at least one pair of wires of two extending in the longitudinal direction. tion extending cores, which in particular run parallel to each other and are surrounded to form a pair shield in pairs of a screen foil. Between the screen foil and the pair of wires, a dielectric intermediate foil is spun around the pair of wires as an additional foil. The additional dielectric intermediate foil is spun around the pair of wires with a varying lay length.
- the data cable is based on a data cable with a longitudinally folded shielding foil with the additional intermediate foil between the pair of wires and the pair shielding.
- Studies have shown that even with such data cables at very high transmission frequencies, a peak-like attenuation occurs. This peak-like attenuation could be significantly reduced by the variation of the lay length of the dielectric intermediate foil. It is assumed that the peak-like attenuation due to a reflection effect due to the introduced by the wrapping of the intermediate foil periodic interference structure with the period of the lay length. In each case a part of the signal is reflected at this interference structure. Due to the strict periodicity, a narrow-band, sharp attenuation at high frequencies is formed due to the reflection effects on the plurality of impurities.
- insertion loss is understood to mean the attenuation experienced by a signal when passing through a signal path (cable length). Due to the periodic structure, this also leads to a high attenuation peak at high frequencies in the so-called return loss (return loss).
- return loss return loss
- Attenuation peak In the case of conventional data cables with the intermediate foil, a comparatively large attenuation (attenuation peak) thus takes place due to the addition of all individual reflections at a fixed, narrow frequency. This results in a high signal attenuation, so that the requirements of the so-called insertion loss (insertion loss) for high transmission frequencies are met only insufficient. In contrast, due to the varying lay length no attenuation peak at a fixed frequency is more present, so that the requirements of Insertion loss is satisfied even at high frequencies. At the same time there is the possibility to extend the lay length and thus to increase the speed of the process and thus to reduce costs.
- lay length or even the pitch of the intermediate foil is understood to be the distance in the longitudinal direction of the cable which the wrapping requires for a 360 ° rotation around the pair of wires.
- the lay length is varied in the range of at least +/- 5% and in particular of at least +/- 10%, based on an average lay length. Even this comparatively small variation has proven to be sufficient to avoid the unwanted attenuation peak.
- An upper limit of the variation is for example +/- 40%.
- the average lay length of the intermediate film is preferably in the range of a few millimeters, in particular in the range of 5 to 15 mm. In particular, the average lay length is approximately between 6 to 8mm. With this lay length, a technically fast and reliable production of the wrapping of the intermediate foil is made possible. It achieves a high process speed. At the same time this can be the desired with the intermediate film Achieve properties, namely a defined, solid wrapping the wire pair to put the screen attached over it in a defined uniform geometry around the pair of wires around, so that no Symmetriestörstellen the screen foil are formed.
- the lay length varies expediently uniformly in the longitudinal direction and in particular continuously, for example sinusoidally.
- the beat length therefore varies between a maximum value and a minimum value around the mean value. This can be achieved in terms of process technology, for example, by varying the withdrawal speed of the wire pair during the strand-spinning process and / or by varying the spin speed.
- the lay length in the longitudinal direction varies periodically with a period length which is preferably in the range of a few meters, in particular in the range of 1 to 5 m and preferably 2 m. Period length of the variation is therefore understood to be the length in the longitudinal direction which lies between two maximum values of the lay length. Although a periodic defect is introduced by this periodicity, this is irrelevant for the transmission frequencies of interest and the typical cable lengths due to the selected period length.
- another, in particular adhesive, outer film is spun around the pair shield. This serves in particular for fixing the entire structure.
- This is again a dielectric film, in particular a PET film.
- this outer film also has a varying lay length.
- the arguments and preferred embodiments given with regard to the intermediate foil are to be transferred in the same way also to this outer foil. It therefore preferably has the same or at least comparable lay lengths and an identical or at least comparable variation of the lay length as the intermediate film. Conveniently, it is spun in the opposite direction to the intermediate film.
- the intermediate foil with a mean lay length is preferably spun around the pair of wires, which is different from a lay length of the shield foil.
- the different damping effects that result on the one hand from the screen foil on the one hand and from the intermediate foil on the other hand due to different physical boundary conditions can in each case be purposefully reduced or avoided.
- the shield foil is spun with constant lay length around the pair of wires.
- the screen film is a longitudinally folded film, that is to say a screen film in which the lay length is infinite.
- the shielding film basically has a multilayer structure with an insulating carrier layer, also referred to as a carrier film, and a conductive layer applied thereto.
- the carrier layer is in particular a dielectric plastic film, in particular a PET film.
- the conductive layer applied thereto is, in particular, an aluminum layer, which is applied to the carrier film, for example by vapor deposition.
- the entire data cable usually further comprises a cable sheath, which is arranged around the at least one pair of wires around.
- the data cable has a plurality of pairs of pairs provided with a pair of shielding, wherein the pairs of conductors usually extend in a stranded manner within the common cable jacket.
- an external shield is typically arranged around the entire composite of the individual pairs of wires. This is, for example, a braided shield and / or a multi-layer shield structure. This external shield is galvanically isolated from the individual pairs. This is achieved in particular via the already mentioned outer film of each pair or also by a common insulating film which surrounds the stranded composite of the wire pairs.

- 5A is a representation of the insertion loss in a conventional shielded wire pair
- 5B is a representation of the insertion loss in a pair of wires, which is provided with a wound with varying lay length intermediate foil,

- FIG. 6B is a representation of the return loss in the pair of cores correlated to FIG. 5B, which is provided with an intermediate foil wound with a varying lay length.
- each wire 4 in turn has a central conductor 6 which is surrounded by a wire insulation 8.
- the wire pair 2 is in each case surrounded by a pair of shielding 10, which surrounds the pair of wires 2 with the interposition of an intermediate film 12.
- the pair shield 10 is formed by a single multi-layered shielding film 14 which forms a carrier layer 16a formed as a PET carrier film and an aluminum coating applied thereon as a conductive layer 16b.
- Layer 1 6b is oriented outwards.
- this is a longitudinally folded screen foil 14, whose longitudinal edges therefore run parallel to the cores 4 in the longitudinal direction 17.
- the wires 4 run untwisted and parallel to each other in the longitudinal direction 17th
- This outer film 20 is again a plastic film.
- Beilaufdrumblete 18 are arranged, which are in electrical contact with the conductive layer 1 6b.
- the filler wires 18 serve for a simplified connection of the pair shield 10 in a connector area.
- the Beilaufdrähte 18 lie on a common center line, which also extend through the center axes of the wires 4. They are in particular outside of the intermediate foil 12 and thus also outside gusset areas between the wires 4. By the opposite arrangement on both sides a highly symmetrical structure is achieved. Alternative configurations with no or only one drain wire are possible in principle.
- All films have a thickness usually in the range of only a few ⁇ . As far as spun foils are concerned, this is especially true in the intermediate film 12 and the outer film 20 is the case, they typically have a width in the range of 4 to 6 mm.
- the intermediate film 12 is wound around the pair of wires 2. This can be seen in particular from the side view according to FIG. 2.
- the intermediate foil 12 is wound around the pair of wires 2 with a mean lay length l m .
- the lay length I and thus the pitch of the intermediate foil 12 in this case varies by a difference ⁇ about the mean lay length I.
- the individual pairs of wires 2 surrounded by the pair shield 10 form a transmission core which is subsequently surrounded by an outer shield 24, which is galvanically isolated from the pair shield 10.
- the outer shielding 24 in the exemplary embodiment is a multi-layered construction with a braid shield 24A on the outside and an inner overall shielding foil 24B, which is preferably designed like the shielding foil 14.
- the outer shield 24 may also be formed in one layer. Between the outer shield and the transfer core, a further insulating film 25 is spun in the embodiment. Finally, a cable sheath 26 as outer protective sheath of the data cable 22 is arranged around the outer shield 24. This is typically an extruded cable sheath 26.
- FIG. 4 shows an exemplary course of the variation of the average lay length I of the intermediate film 12.
- the stroke length I varies by the mean stroke length l m , the difference ⁇ between a maximum stroke length Lax and a minimum stroke length ⁇ mm .
- the variation takes place here at uniform and periodic and in particular according to a sine curve exemplified in Figure 4.
- This course therefore has a periodicity with a period length p, which is typically in the range of a few meters.
- FIGS. 5A and 5B show schematically measured curves in which the attenuation a is plotted in decibels dB versus the frequency f in gigahertz GHz.
- the measured curves were performed on data cables 22 with a basic construction according to FIG. 1 for the pair-shielded pair of wires 2.
- FIGS. 5A, 6A a conventional construction with an intermediate foil 12 with a constant lay length I and with the measuring curves of FIGS. 5B, 6B a buildup with varying lay length I of the intermediate foil 12 was used.
- the measurements were carried out at a mean lay length l m of the intermediate film 12 of about 6mm.
- the lay length I is therefore well above the conventionally chosen lay length of typically about 3mm which is required to shift the attenuation peak to sufficiently high frequencies above 25 GHz if no varying lay length is set.
- FIGS. 5A, 5B shows the curve of the insertion loss [in dB] in comparison of the two cable variants and the diagram pair of FIGS. 6A, 6B shows the profile of the return loss [in dB] in comparison of the two cable variants, respectively plotted against the frequency
- the insertion loss generally increases continuously with increasing frequency.
- the data cable 22 in the variant with the constant lay length shows a very strong attenuation peak, which in the example shown here shows a deflection of more than 50 dB.
- the return loss shows a similar course and likewise at 19 GHz a reflection peak. The height of the peak depends on the absolute attenuation and the line length.
- the data cable 22 with the intermediate film 12 with the varying lay length I in the corresponding frequency range neither a peak in the insertion loss nor one in the return loss.
- the base of the peak is thus significantly widened to a width of preferably several GHz, in particular of, for example, 3-6 GHz. Accordingly, the height of the peak is significantly reduced and it is only a wave-like course over the width in the manner of a noise visible.
- the signal level of this noise is only at a fraction of the original peak height, for example less than 10% of the original peak height.
- Stroke length mean stroke length maximum stroke length minimum stroke length period length
