Broadcast & AV - Cable - Precision Video Coax

Precision Video Coax Cable

In 1995, Belden first launched award-winning digital precision video coax, 1694A. Over a decade later we have a much more extensive line, but to this day 1694A remains the world-wide industry standard for SD-SDI, HD-SDI and 1080p/60 (3G) applications. Many of Belden's digital precision video coax cables are also sweep-tested to 4.5GHz for HD/3G production or swept to even higher bandwidths for 4K transmission. No other cable manufacturer has invested in this technology like Belden has, so no other manufacturer can assure you beyond-high-definition performance like Belden.

  • Specially formulated gas injected high density foam polyethylene is more crush-resistant than standard polyethylene. Even with rough handling during installation, it resists deformation and maintains impedance and return loss characteristics.
  • Belden's skin/foam insulation process provides the right amount of conductor adhesion for easier stripping and improved connector reliability.
  • Compared to SMPTE's return loss limit, Belden's Precision Video Coax provides significant RL headroom to account for potential losses elsewhere in the transmission line.
