AJA FIDO-4R-ST-R0 4-Channel Single-Mode ST Fiber to 3G-SDI Receiver / 10 km Range / Reclocking

Description

The FIDO-4R-ST-R0 is a 4-channel single-mode ST fiber to 3G-SDI receiver designed to convert long-distance fiber signals into standard SDI outputs. It supports 3G/HD/SD-SDI formats and provides electrical isolation to eliminate ground loop issues. The compact low-profile enclosure is built for tight rack, truck, and camera installations.

The receiver accepts four independent simplex ST fiber inputs and provides four independent 3G-SDI BNC outputs. It supports video rates from 150 Mbps up to 3 Gbps and reclocks common SDI rates automatically. The design also supports 4K/UltraHD over four separate fiber links when paired with compatible transmitters.

Optical performance includes a nominal wavelength range of 1260 – 1620 nm, an optical sensitivity down to -18 dBm, and an overload threshold of -3 dBm. Reclocking is available for 270 Mbps, 1.483 Gbps, 1.485 Gbps, 2.966 Gbps, and 2.970 Gbps while other rates are passed through without reclocking. Power consumption is low at a maximum of 5 watts.

Connectivity is straightforward with four ST fiber inputs and four BNC SDI outputs that comply with SMPTE-297 and SMPTE-259/292/424 standards. The unit uses 5-20 VDC input and ships with a universal power supply for global use. A locking power connector and optional P-TAP cable support battery or field power requirements.

Typical applications include long-haul camera links, OB trucks, remote broadcast sites, and studio-to-transmitter fiber runs where ground isolation and signal integrity are critical. The receiver is suitable for professional workflows that require independent channels and low-latency SDI conversion. Its small footprint allows mounting behind monitors or on camera rigs as needed.

Installation is simple and fast due to its compact form factor and standard connectors. The durable enclosure and industry-standard connectors make the unit reliable in field environments. A five year warranty provides long-term support and confidence for production deployments.

Overall the FIDO-4R-ST-R0 provides a cost-effective and technically precise solution for converting single-mode fiber to multiple 3G/HD/SD-SDI outputs. It combines long-distance optical performance with SDI compatibility and robust power options. The unit is an effective choice for broadcasters and AV professionals seeking signal isolation and dependable SDI conversion over fiber.
