Definitions

  • the invention relates to a multi-core transmission cable and in particular Data transmission cable containing at least two separate cable units, an extending over the cable length Separier Quilt and an outer Case has.
  • the Separier Quilt forms individual, in cable longitudinal direction extending receiving channels for each one cable unit. It can this is a chamber profile - a so-called "spline" - from relative intrinsically rigid plastic, the central one supporting strand and of it protruding, between them the receiving channels for each cable unit having forming webs.
  • hybrid cables as transmission cables known in addition to the usual separate cable units, which are usually made of electrically conductive copper, a or several optical fiber cable elements are added to the Bandwidth of usable transmission mechanisms and data transmission capacity to increase.
  • the object of the invention is the advantageous incorporation of the optical waveguide in the transmission cable.
  • the support structure is the used at the outset mentioned Separier Modell. This will be an anyway occupied space, so no relevant cross-sectional expansion caused by the / the additional optical waveguide.
  • 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. Further provides for the electromagnetic shielding of the transmission elements.
  • Execution of the separating structure applies as a chamber profile, runs the at least one optical waveguide in the central support strand of the chamber profile.
  • the support strand is thus also assigned a multiple function, it forms the mechanical backbone of the chamber profile, ensures the strain relief and also serves for mechanical protection of the / additional Optical fiber / s.
  • preferred dimensions are one or more optical fibers in an optical waveguide element arranged, which guides and protects the optical fibers.
  • 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.
  • 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.
  • an outer Plastic sheath 6 made of polyolefin.
  • the wire mesh 7 is an outer shield of the transmission cable achieved.
  • 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.
  • this configuration is a central optical fiber cable element 18 is looped in the peripheral direction.
  • the transverse end B of the metal foil 17th then comes to rest on the bellows of the first fold.
  • the optical fiber cable element 18 itself has four optical fibers 13, which are embedded in a support structure 19.
  • a Separier As is apparent from Fig. 2, according to another embodiment in Cable longitudinal direction a Separier MUST 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.
  • optical waveguides 13 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.
  • 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.
  • FIG. 4 is essentially also designed as that of FIG. 1.
  • 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.
  • FIG. 5 finally, an embodiment is shown in which instead of a Separier Weg 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.
  • 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.
