Features & Specifications
Product Overview +
4-Channel SDI to Fiber Transmission
The FiDO-4T converts four independent 3G-SDI inputs into single-mode LC fiber outputs. Each channel operates separately, enabling simultaneous transport of multiple video signals over fiber.
Independent Channel Operation
All four SDI channels are processed independently, allowing flexible routing and reliable signal conversion without interference between channels. This is ideal for multi-camera or multi-feed workflows.
Long-Distance Fiber Transport
Supports transmission distances up to 10 km (32,808 ft) over standard single-mode fiber, making it suitable for large broadcast facilities, remote production environments, and studio interconnects.
Multi-Format SDI Support
Compatible with 3G, HD, and SD-SDI formats. The system is format-agnostic within supported bandwidths, automatically handling different input signals without manual configuration.
4K and UltraHD Workflow Support
Supports 4K and UltraHD-SDI transmission across four fiber links, enabling high-resolution workflows where multiple channels are used together for combined signal transport.
HDR Metadata Pass-Through
Preserves HDR metadata across the fiber transmission path, ensuring accurate high dynamic range video reproduction and maintaining image integrity.
Flexible Fiber Connectivity
Supports either four simplex LC outputs or two duplex LC connections, providing flexibility in system design and cabling configurations.
Electrical Isolation
Provides electrical isolation between connected devices, helping eliminate ground loop issues and improving signal stability in complex setups.
Compact and Portable Design
The low-profile enclosure allows installation in tight spaces such as racks, trucks, and camera rigs, making it suitable for both fixed installations and mobile production setups.
Reliable Power and Operation
Operates on a 5–20V DC universal power supply with a locking connector to ensure stable and uninterrupted operation in professional environments.
