Laird delivers the most advanced BNC coaxial cables on the market for 12G / 4K UHD applications in broadcast TV, sports, live events, and commercial production workflows. Effectively transmit 12G-SDI signals up to 325 feet. These 12G SDI cables will be able to handle future video formats and signals, making them perfect for new facility installs and broadcast towers.</p><p>This coax cable features enhanced attenuation characteristics that allow transport of 12G signals at much greater distances than comparable sized coax. Cables are fully SMPTE ST-2082-1 compliant and hand crafted with Canare L-5.5CUHD miniature coaxial and BCP-D55UHD BNC connectors. A superb return loss at 12 GHz of 15 dB, 20 dB @ 6 GHz & 26 dB @ 3 GHz makes these cables perfect for 12G, 6G and 3G systems. Designed for Ultra High Definition and 4K signal transmission.</p><p><b>12G-SDI Maximum Distance</b><br />Laird Certifies this cable to work at a Max Transmission Distance of 250 Feet for 12G-SDI even though Canare may show this distance as 300 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.</p>
