This Technical Report describes the procedure to repair damaged CATV cables. The following coaxial cables are considered in this guide: – Coaxial cables with semi air spaced dielectric Outer conductor: copper band, longitudinal welded – Coaxial cables foamed polyethylene or solid polyethylene dielectric Outer conductor: copper band, longitudinal welded – Coaxial cables foamed polyethylene or solid polyethylene dielectric Outer conductor: Overlapped foil of copper or aluminium with braid – Coaxial cables foamed polyethylene or solid polyethylene dielectric Outer conductor: Overlapped foil of copper or aluminium without braid – Coaxial cables foamed polyethylene dielectric Outer conductor: Corrugated copper. This guide is a helpful tool for providers and installers to find out the extend and the effects of damaged cables and to achieve and to evaluate appropriate repair operation. For not buried cables, e.g. indoor cables, the application of this guide is analogous. NOTE The kind respectively the material of the cable sheath makes the coaxial cable an "underground" cable. In the underground area the cable jacket determines the long term behaviour of the cable significantly. For this purpose, only plastics with a high long-term stability are used, usually polyethylene (PE). This material provides protection against ingress of water or water-diffusion with good mechanical properties.
