Mini Converter Optical Fiber 12G 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.
