HF data cables are subjected to more demanding criteria than ordinary copper strands regarding load and deformation. In order to ensure the performance specified in data sheets and standards, they must be used correctly, cared for properly and inspected with appropriate equipment. This handling instruction describes the use of connectors and cable assemblies. It does not replace the inspection of the related data sheets of the connectors, cables and assembly instructions. During the assembly and processing of connectors and cable assemblies, the following items have to be respected. Following chapters are described by means of examples of Fakra and HSD connectors and cable assemblies but suit for any HF-connector.
