Description
The FiDO-4R is a 4-channel single-mode LC fiber to 3G-SDI receiver designed to extend SDI video over long distances with electrical isolation. It converts single-mode LC fiber inputs to four independent 3G/HD/SD-SDI BNC outputs and supports runs up to 10 km. The compact low-profile enclosure is sized for tight rack locations, camera mounts, and mobile production rigs.
Key features include four independent 3G/HD/SD-SDI outputs, support for 4 simplex or 2 duplex LC connections, and automatic reclocking for common SDI rates. The unit accepts video rates from 150 Mbps up to 3 Gbps and can be used as part of a multi-fiber 4K/UltraHD-SDI link when channels are combined. A universal power supply that accepts 5-20 VDC is included for flexible power options.
Technical performance covers a nominal optical wavelength range of 1260 to 1620 nm with optical sensitivity down to -18 dBm and overload tolerance to -3 dBm. Reclocking is automatic for 270 Mbps, 1.483 Gbps, 1.485 Gbps, 2.966 Gbps, and 2.970 Gbps rates while other rates are passed through. The device consumes up to 5 watts and operates reliably between 0 and 40 C.
Connectivity consists of four LC single-mode fiber inputs conforming to SMPTE-297 and four 3G-SDI BNC outputs conforming to SMPTE-259/292/424. The locking power connector prevents accidental disconnection and the unit is compatible with optional P-TAP battery power for field use. The FiDO-4R also provides electrical isolation to help eliminate ground loop issues in distributed systems.
Typical applications include OB trucks, broadcast backhaul, live event production, and studio-to-transmitter links where long-distance SDI transmission is required. It can be used in camera chains, remote enclosures, and fiber I/O panels to bridge fiber infrastructure and SDI equipment. The small footprint and lightweight design allow integration into confined system racks and camera rigs.
Installation is straightforward with no user calibration required and plug-and-play fiber connections. The rugged metal enclosure and proven AJA engineering provide dependable operation and a five year warranty for long-term deployments. FiDO-4R simplifies integration of fiber links into SDI workflows while preserving signal quality and minimizing ground loop risks.
