Features in Depth
The BG-EXH-4KFH extends HDMI 2.0b signals over fiber while preserving the full 18Gbps bandwidth required for uncompressed 4K@60Hz 4:4:4 video. Utilizing single-mode fiber, the system supports transmission distances up to 10km (6.2 miles), making it ideal for large campuses, stadiums, control centers, and other installations where traditional copper cabling is impractical. For shorter deployments, the extender also supports OM4 multi-mode fiber with compatible SFP+ modules, providing transmission distances up to 300m (984ft). Compliance with HDCP 2.2 ensures compatibility with protected Ultra HD content from modern media players, PCs, and other HDMI sources.
Designed to preserve premium audiovisual quality, the BG-EXH-4KFH supports HDR10, HDR10+, Dolby Vision, and HLG, delivering enhanced contrast, brightness, and color accuracy on compatible displays. It also passes advanced multichannel audio formats including Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, and DTS:X, allowing immersive audio to accompany high-resolution video without compromise. Broad support for standard HDTV and VESA resolutions ensures compatibility with a wide variety of displays and source devices.
The extender utilizes a 10G SFP+ LC fiber interface, providing stable, scalable, and interference-free transmission in electrically noisy environments. Fiber-based communication eliminates EMI and RFI issues common with copper installations while maintaining reliable signal integrity over long distances. Combined with its durable metal construction, efficient power consumption, USB-C firmware upgrade capability, and dependable 24/7 operation, the BG-EXH-4KFH is an excellent solution for broadcast facilities, digital signage networks, command centers, educational campuses, healthcare environments, and enterprise AV systems.
