50 FT 8K Fiber Optic HDMI Cable

This unidirectional HDMI 2.1 cable uses optical fiber to transmit 48Gbps signals over 50 feet without compression or electromagnetic interference. It supports 8K at 60Hz and 4K at 120Hz with HDR and eARC for advanced audio control. The slim braided construction suits installations where standard copper cables cannot reach.

Check Source and Display Ports Before Ordering

Verify that your source device and display both provide full-size HDMI 2.1 ports capable of 48Gbps throughput. The cable is unidirectional so the marked source end must connect to the player or console and the display end to the monitor or TV. HDCP 2.2 compliance is required for protected 8K content playback.

Sustained 48Gbps Transmission Over Distance

Optical fiber maintains the full 48Gbps bandwidth across the entire 50-foot length without the signal degradation seen in long copper runs. Light-speed transmission eliminates latency and frame drops during extended gaming or video sessions. The link remains stable under continuous high-resolution load without electromagnetic interference or radiation.

Questions about this item

Does the 50 FT cable include everything needed for an 8K 60 Hz connection or must anything be bought separately?

The single unidirectional fiber-optic HDMI cable carries 48 Gbps 8K 60 Hz HDR eARC and HDCP 2.2 signals end-to-end; no extra adapters or boosters are required.

The listing mentions HDMI 2.0 and 2.1 speeds — which version should I choose for 4K 120 Hz gaming?

HDMI 2.1 at 48 Gbps is required for 4K 120 Hz variable refresh rate gaming; HDMI 2.0 at 18 Gbps only supports 4K 60 Hz.

What does the 48 Gbps figure actually deliver when the cable is installed in a real system?

It enables uncompressed 8K 60 Hz or 4K 120 Hz video with HDR eARC audio and HDCP 2.2 copy protection over the full 50 FT length without signal loss or added latency.
