Pro users are always asking us whether we can supply a video cable that’s optimized for short to medium distances. It should have a low external diameter as well as being highly flexible, suitable for drum storage, and rugged enough to cope with frequent patching. All these enquiries inspired us to design the VD083LP – the ideal cable for mobile transmission of digital video signals over distances up to 70 m. The outer PUR jacket is extra-rugged and abrasion- and notch-resistant, providing outstanding protection for what goes on inside. The ultra-finely stranded conductor is enclosed in physically foamed dielectric medium covered with a dual-layer braided copper shield that provides over 98% protection from interference. In line with SMPTE standards, the VD083LP transmits a 1.5-GB signal over distances of up to 70 m, and a 3-GB signal up to 50 m – or even more in practice, depending on the transmitter and signal frequency! And incidentally, the VD083LP is the “little brother” of our famous and universally appreciated VD125LPS for long distances.
