Quick view

The Gefen GTB-UHD-HBTL is designed to extend 4K Ultra High Definition HDMI signals through a single fiber optic cable enabling distances up to 660 feet at full 4K60 4:4:4 resolution and HDR support.

This device utilizes optical transmission instead of traditional copper cabling to minimize signal degradation and EMI interference over long runs.

It supports HDMI 2.0b specification, HDCP 2.2 compliance, and features both stereo audio and multi-channel embedded audio transmission.

The unit includes EDID management, allowing seamless compatibility with various display devices by emulating or passing through EDID data.

Additional control options include IR pass-through for remote device management and RS232 serial control support for system integration.

Power over fiber is not supported; the transmitter and receiver require separate power supplies.

The fiber optic transmission enables ultra-long-distance 4K60 HDR signal extension without quality loss or latency.

Supports HDR10, Dolby Vision, and HDCP 2.2 ensuring compatibility with modern UHD content protections and formats.

Robust EDID management facilitates integration with a wide range of displays and sources.

Compact design and plug-and-play operation simplify installation in professional AV setups.

IR and RS232 pass-through options enable full remote control and integration with automation systems.

The use of fiber significantly reduces electromagnetic interference and signal degradation compared to copper extenders.

The transmitter and receiver require individual power adapters, increasing setup complexity and cabling.

The price point is higher than traditional copper-based HDMI extenders due to fiber components.

Single fiber cable connection requires proper handling and not as flexible as copper cables in some installations.

No support for Power over Fiber limiting powered remote device options.

Limited to HDMI 2.0b specification, lacking native support for HDMI 2.1 features such as dynamic HDR and enhanced refresh rates.

Does not include built-in audio extraction, requiring external equipment for audio break-out.
