20M SDI Video Cable

R 2,256.00


Our cables are tailored to the digital and analogue world. Whether broadcasting a regional traffic report by a local radio station or transmitting world-class soccer worldwide, the success of broadcast production always depends on the reliability of the audio, video, camera and lighting control cables.

The demands on the studio technique are nearly unlimited. For sports events, politics, culture and news, camera teams have to deliver optimal pictures worldwide, and we are your reliable partner with our high-performance products. Be it studio production or outside broadcasting, analogue or SDI, SDTI or HDTV, live or virtual – we have the right cable for you.

Our products create the conditions for the reliable and safe transmission of signals. Our studio cables fulfil significant specifications like ARD- and BBC-Specification, AES/EBU, SMPTE, IEC, EN and VDE. Thus, we can guarantee optimal transmission characteristics and the very best electromagnetic compatibility.

Characteristic impedance High data rates require a special cable design. Therefore, our audio cables grant a low ER (relative permittivity) and low-loss factor, thanks to foam-skin insulation with narrow tolerances. Thus, our digital audio cables achieve a specified characteristic impedance of 110 and data rates of 3 Mbit/s (single channel) and 6 Mbit/s (two-channel).

Interference immunity Perfectly adjusted twisting of the pairs and an excellent individual screening guarantee interference transmission resistance, immunity to outer interferences and lowest cross-talk, even at high frequencies.

The right cable for every demand Mobile application (e.g. outdoor live transmission of a concert) calls for high flexibility. Our flexible spiralled copper wire screen products are particularly suitable for this purpose. Fixed installations require high performance and the best electromagnetic compatibility. This is guaranteed by an overall screening consisting of aluminium-laminated foil and tight-tinned copper braid.


Video cables are primary used in closed circuit TV systems and in studio applications.
