In einer weiteren bevorzugten Ausführungsform ist es vorgesehen, die Lichtwellenleiter-Kabelelemente mit mindestens zwei Lichtwellenleitern in einer als gelegte Metallfolie ausgebildeten Separierstruktur zu integrieren. Damit ist der Metallfolienliegung eine Doppelfunktion zugewiesen, sie bildet einerseits die angesprochene Zugentlastung und andererseits einen mechanischen Schutz für das Lichtwellenleiter-Kabelelement. Ferner sorgt sie für die elektromagnetische Abschirmung der Übertragungselemente.In a further preferred embodiment, it is provided that Fiber optic cable elements with at least two optical waveguides in to integrate a trained as a laid metal foil Separierstruktur. Thus, the Metallfolienliegung is assigned a dual function, they on the one hand forms the mentioned strain relief and on the other hand one mechanical protection for the fiber optic cable element.

Die in den Fig. 1 bis 5 gezeigten Übertragungskabel haben gemeinsam die Anzahl von vier Kabeleinheiten 1.1 bis 1.4 in Form von Übertragungspaaren, die jeweils aus zwei verdrillten Leitungen 2.1, 2.2 - sogenannten "twisted pairs" - gebildet sind. Die Leitungen 2 selbst bestehen aus einem zentralen Kupferleiter 3 mit einer Isolationshülle 4.The transmission cables shown in FIGS. 1 to 5 have in common the Number of four cable units 1.1 to 1.4 in the form of transmission pairs, each of two twisted lines 2.1, 2.2 - so-called "twisted pairs" - are formed. The lines 2 themselves consist of a central copper conductor 3 with an insulating sheath 4.

Die vier Kabeleinheiten 1.1 bis 1.4 sitzen gemeinsam in einer äußeren Schutzhülle 5, die eine äußere Kunststoffumhüllung 6 aus Polyolefin aufweist. Optional kann radial nach innen aufeinanderfolgend die äußere Kunststoffumhüllung 6 mit einem Drahtgeflecht 7 aus Kupferdrähten und einer inneren Kunststofflage 8 - optional eine Metallfolie - ergänzt sein. Durch das Drahtgeflecht 7 wird eine äußere Abschirmung des Übertragungskabels erzielt. The four cable units 1.1 to 1.4 sit together in an outer Protective cover 5 having an outer plastic sheath 6 made of polyolefin. Optionally, radially inwardly sequentially, the outer Plastic sheath 6 with a wire mesh 7 made of copper wires and an inner plastic layer 8 - optionally a metal foil - be supplemented. Through the wire mesh 7 is an outer shield of the transmission cable achieved.

Das in Fig. 1 gezeigte Übertragungskabel verwendet zur Bildung von Aufnahmekanälen 12 eine in Falten 16 gelegte Metallfolie 17. Die einzelnen Bälge der Falten 16 umschließen jeweils eine der Kabeleinheiten 1.1 bis 1.4, wonach diese Konfiguration um ein zentrales Lichtwellenleiter-Kabelelement 18 in peripherer Richtung geschlungen wird. Insoweit liegt der Anfang A der ersten Falte 16 bei der Kabeleinheit 1.1 radial außen in einer bestimmten Umfangsposition. Das Querende B der Metallfolie 17 kommt dann am Balg der ersten Falte zu liegen.The transmission cable shown in Fig. 1 is used to form receiving channels 12 a folded in folds 16 metal foil 17. The individual Bellows of the folds 16 each enclose one of the cable units 1.1 to 1.4, after which this configuration is a central optical fiber cable element 18 is looped in the peripheral direction. In that regard lies the beginning A of the first fold 16 in the cable unit 1.1 radially outward in a certain circumferential position. The transverse end B of the metal foil 17th then comes to rest on the bellows of the first fold.

Das Lichtwellenleiter-Kabelelement 18 selbst weist vier Lichtwellenleiter 13 auf, die in einer Stützstruktur 19 eingebettet sind.The optical fiber cable element 18 itself has four optical fibers 13, which are embedded in a support structure 19.

Wie aus Fig. 2 deutlich wird, ist gemäß einer anderen Ausführungsform in Kabellängsrichtung eine Separierstruktur in Form eines Kammerprofils 9 vorgesehen, das einstückig aus einem zentralen Stützstrang 10 mit radial davon abstehenden Stegen 11 ausgebildet ist. Diese Stege 11 bilden zwischen sich jeweils die Aufnahmekanäle 12 für die Kabeleinheiten 1.1 bis 1.4. Wie den Figuren nicht näher entnehmbar ist, können auch die Stege 11 in Kabellängsrichtung verdrillt mit einer Schlaglänge von beispielsweise 8 bis 10 Zentimeter angelegt sein.As is apparent from Fig. 2, according to another embodiment in Cable longitudinal direction a Separierstruktur in the form of a chamber profile. 9 provided in one piece from a central support strand 10 with radial thereof projecting webs 11 is formed. These webs 11 form between each of the receiving channels 12 for the cable units 1.1 to 1.4. As the figures can not be inferred, also the webs 11 twisted in the cable longitudinal direction with a lay length of, for example, 8 be created to 10 centimeters.

Im zentralen Stützstrang 10 verlaufen mehrere Lichtwellenleiter 13 - vorzugsweise 2 oder 4 -, womit digitale opto-elektronische Signale über das gezeigte Kabel übertragen werden können. Diese Lichtwellenleiter 13 bestehen in üblicher Weise aus einer Glasfaser oder polymeroptischen Faser (POF). Insoweit ist die Darstellung der Lichtwellenleiter 13 in den beigefügten Figuren übertrieben groß. In the central support strand 10 extend a plurality of optical waveguides 13 - preferably 2 or 4 -, bringing digital opto-electronic signals over the shown cables can be transmitted. These optical waveguides 13 exist in the usual way of a glass fiber or polymer optical fiber (POF). In that regard, the representation of the optical waveguide 13 in the attached Figures exaggeratedly big.

Das in Fig. 3 gezeigte Übertragungskabel unterscheidet sich von dem gemäß Fig. 2 lediglich in einer sogenannten Paarabschirmung 14 in Form einer jeweils um ein Übertragungspaar 1.1 bis 1.4 herumgelegten Metallfolie.The transmission cable shown in FIG. 3 differs from that according to FIG Fig. 2 only in a so-called pair shield 14 in shape one wrapped around a pair of transmission 1.1 to 1.4 metal foil.

Die in Fig. 4 gezeigte Ausführungsform wiederum ist im Wesentlichen ebenfalls wie die gemäß Fig. 1 ausgestaltet. Hier ist im Unterschied dazu lediglich ein Kammerprofil 9' vorgesehen, das auf den Außenseiten seines Stützstrangs 10 und der Stege 11 mit einer elektrisch leitenden Metallschicht 15 belegt ist. Damit lassen sich die Aufnahmekanäle 12 nochmals in verbesserter Weise gegeneinander abschirmen, was als separate Maßnahme oder auch in Verbindung mit der in Fig. 2 gezeigten Paarabschirmung 14 für hoch-übersprechgedämpfte Kabel realisiert werden kann.The embodiment shown in FIG. 4, in turn, is essentially also designed as that of FIG. 1. Here is the difference only a chamber profile 9 'provided on the outer sides of his Support strand 10 and the webs 11 with an electrically conductive metal layer 15 is occupied. This allows the recording channels 12 again shielded against each other in an improved way, what as a separate measure or also in conjunction with the pair shield shown in Fig. 2 14 can be realized for high-crosstalk attenuated cable.

In Fig. 5 schließlich ist eine Ausführungsform gezeigt, bei der statt einer Separierstruktur 9 lediglich ein Stützstrang 10 im Zentrum des Übertragungskabels vorgesehen ist. Dieser Stützstrang 10 nimmt vier Lichtwellenleiter 13 auf. Im Übrigen entspricht dieses Übertragungskabel, was die Ausführung der Kabeleinheiten 1.1 bis 1.4 und die äußere Schutzhülle 5 betrifft, der Ausführungsform gemäß Fig. 3. Insoweit kann auf die dortigen Erläuterungen verwiesen werden.In Fig. 5, finally, an embodiment is shown in which instead of a Separierstruktur 9 only one support strand 10 in the center of the transmission cable is provided. This support strand 10 takes four optical fibers 13 on. Incidentally, this transmission cable corresponds to what the Execution of the cable units 1.1 to 1.4 and the outer protective cover 5 concerns, the embodiment of FIG Explanations be referenced.
