The Blackmagic Design Teranex Mini Optical to HDMI 12G is a compact, professional media converter designed to receive a high-quality 12G-SDI video signal transmitted over single-mode optical fiber and convert it to an HDMI output. This device is engineered for broadcast, live event, and installation environments where ultra-long cable runs are required between a video source and a display or monitoring location. Fiber optic transmission offers significant advantages over traditional copper cabling, including immunity to electromagnetic interference (EMI), no ground loop issues, and the ability to carry a signal for several kilometers without any degradation or the need for signal boosters. The converter simplifies the integration of fiber infrastructure into modern video workflows by providing a straightforward optical-to-HDMI interface.

This unit is part of the Teranex Mini series, which is renowned for its high-quality processing. It features advanced scaling capabilities, allowing it to intelligently convert the input resolution to match the optimal output for the connected HDMI display, even if the native formats differ. The device also includes a built-in frame synchronizer, which locks onto the incoming optical signal and outputs a perfectly stable, genlocked HDMI signal—this is crucial for eliminating glitches when switching between multiple unsynchronized sources in a production environment. Setup and control are facilitated through a front-panel LCD screen and buttons, or remotely via Ethernet using the included Teranex Mini Software Utility, offering flexibility for both field use and rack-mounted installations.

Housed in a durable, all-metal enclosure, the Teranex Mini Optical to HDMI operates silently with fanless cooling and can be powered via the included AC adapter or through its USB-C port, adding to its deployment versatility. By providing a reliable, high-fidelity bridge between long-haul fiber networks and standard HDMI monitors, projectors, or capture devices, this converter is an essential tool for extending the reach of 4K video signals in stadiums, broadcast campuses, large venues, and any production scenario where signal integrity over distance is paramount.
