Abstract: The cable protective tube comprises a semiconductor sensor (1a) and/or information carrier that is suitable for detecting measuring variable relevant for a capacity/function of tubes and that is integrated into the tube wall by a plastic-technical forming process during the production of the tubes. The sensor or information carrier consists of microchip or exists in a form of a microchip for storing data, which concerns for a characteristics of the tube, for the proper functioning of the tube or cable laid in the tube or cable line relevant measured variables. The cable protective tube comprises a semiconductor sensor (1a) and/or information carrier that is suitable for detecting measuring variable relevant for a capacity/function of tubes and that is integrated into the tube wall by a plastic-technical forming process during the production of the tubes. The sensor or information carrier consists of micro chip or exists in a form of a microchip for storing data, which concerns for a characteristics of the tube, for the proper functioning of the tube or cable laid in the tube or cable line relevant measured variables, or also data for relocation and installation, characterization and identification of cables laid in the cable line or for their maintenance relevant data. The sensor/information carrier is intended to detect or store a physical variable concerning a cable laid in this cable protective tube or a cable line laid in this. The sensor is suitable to detect a wavelength of light or other electromagnetic waves, which are guided by the cable or the cable line. The cable is made up of glass fibers, synthetic fibers, mineral polymer fibers or metals as conducting or transferring media. The sensor is worked in the production of the tubes into the non-plastic of the tube wall before its cooling. The tube is produced by an extruding and the sensor at the same time is extruded into the tube wall. The sensor is brought into the tube wall, so that it does not protrude out the tube wall outer radially and/or does not protrude over inner radially into the light cross-section of the tube. The tube is manufactured as endless tube in continuous manufacturing. The sensor or information carriers are arranged with distance to each other along a metrically fixed chain on a spiral line around the longitudinal axis of the tube in the tube wall. The sensors detect the strength of a signal guided in the cable or cable line or the amplitude of the cable or an electromagnetic wave led into the cable or the line. The sensor is provided to examine or to monitor the function or a property of the cable or the line. The sensor is equipped with means, which enables the precise discrimination orientation of this sensor by means of a satellite monitor. The sensor/information carrier comprises a small-dimensioned chip selected from chip scale packages (CSP), ball grid array (BGA), flip chip, memory chip or the like. The information stored in the sensor/information carrier is enquired by means of electro magnetic waves, magnetic induction or ultrasonic. The tube consists a jacket tube, which takes up a majority of interior tubes assigned by individual cables or groups of cables. The jacket tube has a round outline and takes up variable number of inner tubes, which are relocatable in the jacket tube in an axial direction.
