The Canare BCJ-JK is a standalone gender changer/extension type BNC feed-thru adapter designed specifically for 12G applications. Until now, very little has been offered for 12G signals in the way of extension adapters and receptacles. Now Canare has several solutions to keep your 12G signal flowing smoothly and patched accordingly! In 2015, SMPTE released ST 2082-1 12G-SDI, a standard for UHD-SDI (4K 2160p), as the next-generation of the single-link SDI format. 12G-SDI makes possible transmission of as much as eight times the data volume of HD-SDI (2K 1080i), and as much as four times the data volume of 3G-SDI (2K 1080p) over a single coaxial cable. At the same time, high performance is also required of both cables and connectors and that's where they come in. Canare has everything you need to get your 12G signal to where it's got to go..be it anywhere on the planet and beyond.
