12G-SDI over Fiber

The USXT² is a 12G-SDI optical extender for transmitting 4K UHD SDI signals over long distances using singlemode optical fiber.

12G-SDI Professional Fiber Optic Extender heavy duty

When copper SDI falls short

As 12G-SDI copper cabling often bumps into limitations as to the maximal transmission distance, we have come up with this compact and sturdy all-in-one solution.

Our Professional SDI fiber extenders takes care of every possible SDI standard and switches automatically to the right bandwidth. The used SDI rate can be verified thanks to the discrete status LED on the side of the units.

Small but tough

You might have noticed the new design: we've chosen an even stronger and higher quality enclosure made out of primary grade extruded aluminum, featuring rubber corner protectors and a sleek anodized finish.

Its small dimensions (176mm x 105mm x 56mm) allow for easy handling and storage. On the back we fitted our well known threaded truss hole for stand- or truss mounting.

Truss & Clamp mounting

All of our extender units come with an M10 threaded mounting hole for attaching or clamping the extenders on trusses, bridges, tripods, and many more.


Plug & Play to the Extreme

The UHD BNC bulkheads are fed directly out of the enclosure to ensure minimal signal loss.

Powered by a Neutrik powerCON TRUE1 TOP inlet ensuring a safe and reliable connection.
