Abstract: The invention relates to a method for creating a fibre strip (12) composed of individual fibres (11). some sections of the latter (11) being subjected to a surface treatment, far example by moms of a laser (13). According to the invention, the individual fibres (11) are conducted in the fibre strip (12) without torsion, at least between the treatment process step and the fitting process step to prevent distortion. This ensures that the angular position of the surface-treated sections in the fibre strip (12) can be advantageously predicted and that the optical behaviour of the fibre strip, which is dependent on the flexure, permits conclusions to be drawn about the degree of bonding in the fibre strip. The fibre strip can be used, for example, as a sensor strip, which can be utilised in the bumper of a motor vehicle to identify the impact of pedestrians.

Abstract: At least one sensing region is formed on the bending sensor by providing a flexurally elastic base cover which is interrupted in at least one partial region of the sensing region or is structured using elevations and/or depressions. At least one planar optical fiber core is generated on the base cover. The optical fiber core has a greater index of refraction than the base cover. The optical fiber core is covered by a shroud. The optical fiber core has a greater index of refraction than the shroud.

Abstract: A device (V) for fixing at least one fibrous strip (FB) to a body part (K), wherein the fibrous strip comprises at least one fibre (F) embodied as a fibre-optic bending sensor, has at least one fixing unit (BE) which respectively has (a) a fixing part (BM) for applying part of the fibrous strip to the body part, and (b) at least one fixing loop (BS) for guiding the fibrous strip along an axis of a three-dimensional space. The fixing loop can be fixed to the body part.

Abstract: A fibre optic ribbon has several individual optical fibres, provided, for example, for application of the ribbon conductor as flex sensor trip, with surface-treated partial regions in which individual optical fibres can be provided. The individual fibres are arranged in a support strip with a space between, such that a treatment of the individual fibres, which permits a particularly simple execution of the surface treatment. The individual fibres are treated with removal of the support strip in the partial regions and finally the support strip is provided with a sleeve. Additional passive optical fibres can be inserted in the spaces for protection of the individual fibres during the surface treatment which give additional protection to the individual fibres.

Abstract: A cable network with a light waveguide cable which is introduced in the pipeline of an existing pipeline system. The light waveguide cable is arranged along a line, preferably at the vertex of the pipeline, and is provided with a protective layer so that a smooth transition exists between the wall surfaces of the pipeline and the cable.

Abstract: A hybrid cable with optical fibers and metallic conductors has a cable jacket with a first slot (14) for reception of optical fibers (121, 122) as well as a second slot (24) for reception of the electrical conductors (221, 222). The parts (1, 2) of the cable jacket forming the slots are connected to one another with a crosspiece. The cable has a preferred bending line, which is formed by the symmetrical axis (4) of the cable. The cable is especially suited for optical signal transmission in combination with the transmission of electrical data signal or supply voltage.

Abstract: A solid optical lead formed by a light waveguide having at least two coatings composed of plastic material having an outer layer which is applied directly on the inner layer and is constructed as a flame-retardant layer. The outer layer is constructed as a halogen-free material and comprises an additive that will prevent an adhesion between the outer layer and the inner layer and, thus, assures a good strippability of the outer layer from the inner layer.
