NP 111E - New Belden Brilliance® heat-resistant cable: Meeting high performance needs for HDTV

To meet the high performance requirements of HDTV camera systems, Belden has introduced Brilliance® 7804Ex. These hybrid fiber optical cables are designed to surmount over-heating problem experienced in outside HDTV broadcasting. This is particularly common with black cables in direct sunlight because their internal resistance can be reduced to below critical level causing the camera to shut down in case of short circuit.

Heat resistant Brilliance® 7804X are designed to overcome these problems through the use of insulation with a higher thermal stability. This makes it ideal for use in outdoor as well as indoor transmissions: to link different cameras to an OB van in outside broadcasting or to service permanent installations connecting studio cameras to the control room. When a patch panel is used, a whole range of video images on different channels becomes available.

Brilliance® 7804X is a composite cable which includes a high voltage power line for HDTV camera, two control lines and two optical fibers for video and audio transmission. The cable is available in three versions: halogen-free and PVC versions for studios and permanent installations and a PUR version for mobile applications. All of them are available with put-ups of 305, 500 and 1000m and can be supplied with special put-up for easy connecting on the drum.
