The 12G-SDI Fiber Optic Extender is designed for long-distance transmission of uncompressed SDI video signals over single-mode optical fiber. It supports full SDI formats from SD-SDI to 12G-SDI, delivering high-quality video up to 4K@60Hz without latency or signal loss.

With strong anti-interference capability and stable performance, it ensures reliable operation in demanding environments. The LC SFP optical interface supports transmission distances up to 20KM (depending on module type).

The built-in SDI loop out enables simultaneous local monitoring while transmitting the signal to a remote location, making it ideal for broadcast, live production, and professional video applications.

Featuring automatic signal detection, built-in equalization, and ESD protection, the device ensures stable transmission and clear image quality. Its plug-and-play design and flexible power options ( 5–12V or rack-mounted power supply) make it suitable for both fixed installations and mobile use.
