The Laird HDBNC4855 Series of low profile coax HD-BNC to BNC male adapter cables are designed for transmitting high resolution uncompressed 12G-SDI / 4K UHD video signals. Ideal for high density jackfields, routers and signal distribution systems where RF performance is critical. The HD-BNC utilizes a bayonet style mating analogous to traditional BNCs for a reliable coupling. These Laird cables are built with Belden low loss 4855R coax rated for 12G-SDI runs up to 150 feet. The cable's new braid design, silver-plated copper conductor, and a new polyethylene formula are all design features that contribute to significant RL improvement and an 8 dB improvement on cable attenuation compared to existing coaxes. Fully compatible with SMPTE ST-2082-1 and ST-2081-1 standards.
12G-SDI Maximum Distance
Laird Certifies this cable to work at a Max Transmission Distance of 117 Feet for 12G-SDI even though Belden may show this distance as 149 Feet. To meet the Laird max transmission standard, signal integrity must remain 100% functional without any CRC errors. Your 12G-SDI ST 2082 signals may function at or beyond the manufacturer-certified lengths without issues; however, when CRC errors are present there could be drops in audio, video, meta, and ancillary data. In most circumstances, video integrity remains intact at OEM distance.
