AJA FiDO-4T-ST, 4-Channel 3G-SDI to Single-Mode ST Fiber Transmitter

High-Density 4-Channel SDI to Fiber Conversion

The AJA FiDO-4T-ST is a professional 4-channel 3G-SDI to Single-Mode ST Fiber transmitter designed for demanding broadcast and pro-AV environments. This mini-converter allows for the transport of four independent SDI signals over long distances up to 10 km (32,808 ft) using fiber optic cable. By utilizing fiber, users benefit from complete electrical isolation, which is essential for eliminating ground loop interference in complex setups.

Versatile 4K and Multi-Channel Workflows

Equipped with four independent 3G/HD/SD-SDI inputs, the FiDO-4T-ST offers incredible flexibility. It can be used to manage four separate signal paths or to transport 4K/UltraHD-SDI content over four fiber links. The industry-standard ST connectors provide secure and reliable simplex output connections for high-stakes production workflows.

Compact, Field-Ready Design

AJA Mini-Converters are renowned for their rugged, low-profile enclosures. The FiDO-4T-ST fits easily into tight spaces behind equipment racks, inside mobile production trucks, or mounted directly to camera rigs. For maximum reliability, it features a locking power connector to prevent accidental downtime. The unit includes a DWP-U-R1 universal power supply with international plugs, and it can also be powered via battery in remote locations using an optional P-TAP cable.
