Product Overview +

4-Channel Fiber to SDI Conversion

The FiDO-4R-MM converts four independent multi-mode LC fiber inputs into 3G-SDI outputs, allowing seamless integration of fiber-based video signals into SDI workflows.

Independent Channel Operation

Each of the four channels operates independently, enabling simultaneous reception of multiple video feeds without cross-interference or signal dependency.

Multi-Mode Fiber Support

Designed for multi-mode fiber installations, it supports transmission distances up to 300 m on OM3 fiber and up to 700 m on OM4 fiber, making it ideal for studio environments and short-to-medium range production setups.

4K / UltraHD-SDI Workflow Compatibility

Supports 4K and UltraHD-SDI over four fiber links, allowing high-resolution content workflows where multiple synchronized feeds are required.

Flexible Fiber Input Options

Supports both simplex and duplex LC fiber input configurations, providing flexibility with 4 simplex or 2 duplex connections depending on infrastructure design.

HDR Metadata Pass-Through

Maintains HDR metadata across all channels, ensuring accurate high dynamic range video reproduction without degradation of image quality.

Electrical Isolation

Provides electrical isolation between connected systems, helping eliminate ground loop issues and improving signal stability in complex broadcast environments.

Compact and Portable Design

The low-profile enclosure is designed for tight installation spaces such as equipment racks, OB trucks, and camera rigs, making it suitable for both fixed and mobile applications.

Reliable Power System

Operates on a 5–20V DC universal power supply with a locking connector to ensure stable and secure operation in professional environments.
