A storage device for data transmission lines, which serve for data transmission between a moving object and a base station, has a spool unit ( ) on which a data transmission line ( ) is wound in the form of a package of several layers ( ) of windings. The windings in each layer are introduced at a maximum tensile stress or force, which is dependent on the modulus of elasticity of thedata transmission line ( ). In this way, a creep or flow of the material of data transmission line ( ), which is due to the pressure that is produced on the individual layers ( ), is reduced or avoided, and a stable ordering of the windings is assured over a long period of time. The pressure of a winding on the layer ( ) lying thereunder is less than 0.6 N/mm , at least in the lower region of the windings. The maximum tensile stress is calculated from the diameters of data transmission line ( ) and spool unit ( ), the modulus of elasticity of data transmission line ( ) and the total number N of layers ( ) of the package.

Payout device for data transmission lines and method for the production of payout device

A coil support and a winding arranged thereon, especially one including a fiber-optic waveguide, whose turns are mutually fixed by a binding agent. The binding agent drys while a volatile solvent diffuses off. The coil support is permeable to solvent and is designed such that it has essentially the same coefficient of thermal expansion as the winding. This achieves the uniform, thorough drying of the binding agent over the entire winding and reduces the risk of damage to the fiber-optic waveguide during the transportation and the unwinding of the winding in a coil form.

Coil form

A coil form with a coil support and with a winding applied thereto, whose turns are provided with a coil bond material. The bond material contains a volatile solvent and mutually fixes the turns when dried (in a dry state). To guarantee an essentially uniform, nearly solvent residue-free drying of the coil bond in the entire winding even in the case of a very large number of coil layers, the coil support is a porous coil support having open pores. The coil support has a diffusion coefficient with respect to the solvent that is equal to or slightly lower than that of the winding.
