AJA FiDO-4R-ST, 4-Channel Single-Mode ST Fiber to 3G-SDI Receiver

Professional 4-Channel Fiber to SDI Conversion

The AJA FiDO-4R-ST is a high-performance 4-channel single-mode ST fiber to 3G-SDI receiver designed for demanding broadcast and pro-AV environments. It provides a cost-effective solution for transporting high-quality video over long distances, supporting cable runs up to 10 km. By utilizing fiber optics, the FiDO-4R-ST ensures complete electrical isolation, effectively eliminating ground loop issues that often plague copper-based setups.

Versatile 4K and Multi-Channel Workflows

Equipped with four independent 3G/HD/SD-SDI outputs, this converter is capable of handling four separate signals or a single 4K/UltraHD signal over four fiber links. Its versatility makes it an essential tool for OB vans, live event production, and studio infrastructure where space and signal integrity are paramount.

• 4 simplex ST fiber input connections
• 4 independent 3G-SDI outputs
• Support for 4K/UltraHD-SDI transport
• Input range: 5-20VDC (DWP-U-R1 universal power supply included)

Compact, Field-Ready Construction

The AJA FiDO-4R-ST features a compact, low-profile enclosure that fits seamlessly into tight spaces, whether mounted behind a monitor or integrated into a complex camera rig. The locking power connector prevents accidental disconnection during critical broadcasts, while the optional P-TAP cable allows for battery operation in remote field locations.
