Multimedia lines are used in different ways. In the automotive industry, data wires are used in high-frequency applications, such as coax cables or HSD (High Speed Data) lines. These shielded cables are used for camera systems, control displays or USB connection systems. The range of high-frequency cables is very flexible and changeable, as the frequency ranges are assigned to various factors. Applications, country-specific specifications and the time period: all of this play a major role.
