AJA FiDO-R-12G-ST 12G-SDI ST Fiber Receiver

AJA FiDO-R-12G-ST 12G-SDI ST Fiber Receiver

The AJA FiDO-R-12G-ST is a compact single-channel single-mode ST fiber to 12G-SDI receiver designed for long-distance professional video signal transport. It converts a single-mode fiber signal to dual 12G-SDI outputs, with support for 12G-SDI, 6G-SDI, 3G-SDI, HD-SDI, and SD-SDI formats.

Using standard single-mode fiber, the FiDO-R-12G-ST supports transmission distances of up to 10 km (32,808 ft). Its locking ST barrel connector provides secure fiber connectivity, making it well suited for live events, mobile production, broadcast facilities, and other environments where reliable connections are important.

12G-SDI Fiber to SDI Conversion

The AJA FiDO-R-12G-ST converts a single-mode fiber signal to 12G-SDI, providing a reliable solution for long-distance video transport in professional production environments.

The receiver supports a wide range of SDI formats, including 12G-SDI, 6G-SDI, 3G-SDI, HD-SDI, and SD-SDI. This allows the FiDO-R-12G-ST to work with both modern 4K production systems and established HD-SDI infrastructure.

The receiver provides two matching SDI outputs, allowing the converted signal to feed two SDI devices or function as a simple SDI distribution point.

Long-Distance Single-Mode Fiber Transmission

FiDO-R-12G-ST supports transmission distances of up to 10 km (32,808 ft) over standard single-mode fiber optic cable.

Fiber provides a practical solution for transporting high-bandwidth SDI signals over distances that would be difficult or impractical with traditional copper SDI cabling. This makes the receiver useful for connecting cameras, production equipment, control rooms, and other video systems across large venues or facilities.

Secure Locking ST Fiber Connection

The FiDO-R-12G-ST features a locking ST barrel connector designed for secure fiber connectivity. The locking connection is particularly advantageous in live event, mobile production, broadcast, and field production environments where equipment and cabling may be frequently moved or handled.

The unit uses a simplex single-mode fiber connection for long-distance SDI signal transport.

Dual 12G-SDI Outputs

The FiDO-R-12G-ST provides two matching SDI outputs carrying the same converted signal. This allows a single fiber source to feed two downstream SDI devices without requiring a separate SDI distribution amplifier.

Both outputs support the incoming SDI format, including 12G-SDI, 6G-SDI, 3G-SDI, HD-SDI, and SD-SDI.

HDR Metadata Pass-Through

The FiDO-R-12G-ST supports SDI metadata pass-through, including HDR metadata, helping preserve important signal information during fiber-to-SDI conversion.

High Dynamic Range (HDR) provides a wider range of brightness and color than Standard Dynamic Range (SDR), allowing compatible production systems to maintain brighter highlights, deeper blacks, and richer color detail.

Compact AJA Mini-Converter Design

The FiDO-R-12G-ST uses AJA's compact Mini-Converter enclosure, making it easy to install where space is limited. The low-profile design can fit behind monitors, inside equipment racks, in mobile production trucks, or directly on camera rigs.

A locking power connector helps prevent accidental power disconnection. An optional P-TAP power cable can also provide battery-powered operation for remote production applications.

Universal Power Supply

The FiDO-R-12G-ST operates on 5-20VDC power and includes a universal power supply with international plug connections. Spare universal power supplies are also available for AJA Mini-Converters, providing additional flexibility for professional production environments.

Professional AJA Support and Warranty

AJA provides technical support for Mini-Converter installation, configuration, operation, and troubleshooting. The FiDO-R-12G-ST is covered by a five-year warranty, providing long-term support for professional video production systems.
