About AJA FiDO-4T

FiDO-4T offers unmatched flexibility and cost efficiency for SDI-Fiber conversion, allowing for long cable runs up to 10 km (32,808 ft) with electrical isolation - useful for eliminating ground loop problems.

FiDO converters use a compact, low-profile enclosure that works well in tight spaces around and behind equipment racks, trucks and on camera.

Universal Power Supply
All AJA Mini-Converters ship with a universal power supply that includes international plug connections for use around the world.

Compact and Portable
AJA Mini-Converters are small enough to fit behind a monitor, in the back of a rack, or directly on a camera rig. A locking power connector can't accidentally pull loose and an optional P-TAP power cable allows for battery power in remote locations.

AJA Mini-Matrix
Information on the complete line of AJA Mini-Converters is now available as a mobile app on iOS. The Mini-Converter product line is extensive and this app helps you find the right converter for any situation, wherever you are.

Individual products have links back to the main AJA website for more details and you can email product information directly from the app. The free AJA Mini-Matrix app for iPad and iPhone is available now in the Apple iTunes Store.
