Know before you buy
Yes, the L-3.3CUHD-984-RD is specifically engineered for high-bandwidth 12G-SDI transmission, making it fully capable of supporting both 4K and 8K video infrastructures.
Yes, this cable carries a UL 1666 Riser rating, which means it is certified for use in vertical runs and general-purpose installations within walls and plenums where flame resistance is required.
The highly-foamed PE insulation is designed to minimize signal attenuation, or loss, which is critical for maintaining signal integrity over the long 984-foot length of this cable.
It features a dual-layer shielding system consisting of copper foil and a high-density tinned copper braid, providing robust protection against electromagnetic interference in professional broadcast environments.
While it is built for durability with a 21 AWG center conductor, it is a professional-grade coaxial cable with a 0.217-inch outer diameter. It is designed for reliability in permanent installations rather than frequent movement or tight-radius patching.
Yes, every unit is sweep tested to ensure it meets strict impedance and attenuation standards across the required frequency range, providing consistent performance for high-stakes broadcast applications.
