4K is playing 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). In practice, however, this proves to be uneconomical. A single-link transmission with 12 Gbit/s is to be aimed for.
According to the SMPTE ST 2082 standard, the format transmits 4K video signals with a resolution of 3840 x 2160 pixels and a data stream of 12 Gbps. This corresponds to a half clock frequency of 6 GHz. The standard also provides for a maximum permitted attenuation of 40 dB. Based on these specifications, the Multimedia Solutions (MMS) BU of the Prysmian Group has designed the UHD coaxial cable series for the transmission of 4K video signals.
The UHD series includes, for example, the UHD50 and UHD100. In the development of the new series, MMS placed great emphasis on taking into account the requirements of OB van manufacturers - for example, adhering to the outer cable diameters of 4.5 and 7 millimetres. MMS has achieved this by increasing the cellulose content of the dielectric and by using a silver-plated and optimised inner conductor.
