4K is on

4K plays an increasingly important role in the transmission of video signals. For technical reasons, 4K transmissions are mainly carried out in Quad Link (4 x 3 Gbit/s). However, this proves to be uneconomical in practice. A single link transmission with 12 Gbit/s should be aimed for.

According to the SMPTE ST 2082 standard, the 4K format transmits video signals with a resolution of 3840 x 2160 pixels and a data stream of 12 Gbit/s. This corresponds to half a clock frequency of 6 GHz. The standard also provides for a maximum allowed attenuation of 40 dB. Based on these specifications, the BU Multimedia Solutions (MMS) of the Prysmian Group has designed the UHD coaxial cable series for the transmission of 4K video signals.

The UHD series includes the UHD50 and UHD100, for example. In developing the new series, MMS placed great emphasis on taking into account the requirements of OB vehicle manufacturers – for example, compliance with the external cable diameters of 4.5 and 7 millimetres. MMS has achieved this by increasing the cell structure of the dielectric and a silver-plated and optimized inner conductor.
