12G-SDI over Fiber

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

12G-SDI Fiber Optic Extender

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 USXT² 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.

Plug & Play to the Extreme

The UHD BNC bulkheads are ruggedized with heavy duty rubber gaskets. We have chosen to feed them directly out of the enclosure to ensure minimal signal loss.

Power is provided by a Neutrik powerCON TRUE1 TOP inlet ensuring a safe and reliable connection.

Choose your Fiber

Neutrik's opticalCON DUO chassis is compatible with standard LC Duplex multimode or singlemode cable.

We recommend using opticalCON DUO X-TREME fiber cable for heavy duty applications such as staging, rental or field use.
