Low-loss coaxial 75 ohm cable specifically for 3GHz HDTV and serial digital video signals.
Wiring specifications for many public buildings now call for LFH cables to be used in certain areas, notably in corridors etc. Under combustion circumstances LFH cables have a significantly reduced smoke emission and the gaseous products contain no toxic halogens.
SDV-L-LFH is technically identical to standard SDV-L, except that insulation and jacket materials are replaced by LFH (low fire hazard) materials. This makes no difference to the electrical properties, but the cable is a little stiffer.
Note: See suitable connectors for this cable in the drop-down lists below the full cable specification.
