A hybrid cable containing single-mode fibre optic and copper cores, meeting the SMPTE311M standard for HDTV camera connections. It handles video, audio and control signals plus powering between camera and base units. It is suitable for use with the special hybrid connectors produced by manufacturers such as Canare and Lemo.
The cable is available with a choice of four outer jackets -
- Flexible polyurethane (PU) - a robust jacket suitable for OB and studio floor use, with excellent abrasion resistance.
- High Flex (TPE) – an ultra-flexible jacket, significantly more flexible than the PU version.
- Low-smoke, halogen-free (FRNC), low fire hazard (LFH) version meets or exceeds IEC 60332-1, IEC 60754-2 and IEC 61034 for building installation.
- Low-smoke, halogen-free (FRNC-C), low fire hazard (LFH) version (with additional PET/foil layer) meets or exceeds IEC 60332-3-24 for building installation.
