AJA FiDO-T-MM 3G-SDI to Multi-Mode Fiber Transmitter

AJA FiDO-T-MM 3G-SDI to Multi-Mode Fiber Transmitter

The AJA FiDO-T-MM is a compact 3G-SDI to multi-mode LC fiber transmitter designed to transport professional SDI video over multi-mode fiber. It supports 3G-SDI, HD-SDI, and SD-SDI inputs and provides a looping SDI output for convenient integration into existing video workflows.

FiDO-T-MM supports fiber runs of up to 700 meters (2,296 feet) over OM4 multi-mode fiber and up to 300 meters (984 feet) over OM3 fiber. Fiber connectivity also provides electrical isolation, which can help eliminate ground loop problems in professional video systems.

3G-SDI to Multi-Mode Fiber Conversion

The AJA FiDO-T-MM converts 3G-SDI, HD-SDI, and SD-SDI signals to multi-mode LC fiber, providing a reliable method for transporting professional video over longer distances.

The transmitter is designed for use with standard multi-mode fiber and supports both OM4 and OM3 fiber infrastructure. This makes FiDO-T-MM suitable for broadcast facilities, live events, studios, mobile production, and professional AV installations.

Multi-Mode Fiber Transmission Distances

FiDO-T-MM supports different maximum transmission distances depending on the multi-mode fiber type:

• OM4: Up to 700 meters (2,296 feet)
• OM3: Up to 300 meters (984 feet)

Fiber allows professional video signals to be transported farther than traditional copper SDI cabling while also providing electrical isolation between connected equipment.

SDI Loop-Through

The FiDO-T-MM includes an SDI loop-through output, allowing the incoming SDI signal to continue to another piece of SDI equipment while simultaneously being converted to fiber.

This makes the transmitter useful in camera, studio, live event, and broadcast workflows where the original SDI signal needs to remain available locally.

HDR Metadata Pass-Through

FiDO-T-MM supports SDI metadata pass-through, including HDR metadata, helping preserve important signal information during SDI-to-fiber 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.

Electrical Isolation for SDI Systems

Fiber-based signal transport provides electrical isolation between connected equipment, which can help eliminate ground loop problems.

This can be particularly useful in professional production environments where cameras, video equipment, displays, and other systems may be powered from different electrical circuits.

Compact and Portable Mini-Converter

The FiDO-T-MM uses AJA's compact, low-profile Mini-Converter enclosure, making it easy to install in space-constrained production environments.

The unit can fit behind monitors, inside equipment racks, in mobile production trucks, or directly on camera rigs. A locking power connector helps prevent accidental disconnection, while an optional P-TAP power cable can provide battery-powered operation for remote applications.

Universal Power Supply

FiDO-T-MM 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.

Professional AJA Support and Warranty

AJA provides technical support for Mini-Converter installation, configuration, operation, and troubleshooting. The FiDO-T-MM is covered by a five-year warranty, making it suitable for long-term professional video production and AV applications.
