The Blackmagic Design 12G BiDirectional SFP Optical Module works with Blackmagic Design Mini Converter Optical Fiber 12G. The Mini Converter Optical Fiber 12G (sold separately) converts SDI to optical fiber and optical fiber to SDI in both directions at the same time, you can even have different video standards going in each direction! The 12G‑SDI connections are multi rate, which makes it compatible with all SD, HD and Ultra HD formats and equipment up to 2160p60, including Level A and B devices. You can install any standard 3G, 6G or 12G‑SDI SFP optical fiber module so you can send SDI using the same low cost optical fiber cables that are commonly used for computer networks. Blackmagic Mini Converters are the world’s most advanced converters because they include the latest 6G-SDI technology, automatically detect the input video format and instantly change between virtually all SD, HD and Ultra HD video standards up to 2160p30! You get advanced features such as redundant SDI inputs, re‑clocked loop outputs, HDMI instant lock, 33 point LUT support, and full analog and AES/EBU audio connections so you can convert video, as well as embed or de-embed audio! Choose from a wide range of 3G and 6G-SDI models, depending on the conversion you need!
