Highwings HDMI 2.1 75ft 48Gbps Fiber Optic Cable
Product description
This optical fiber HDMI cable from Highwings delivers long-reach, high-bandwidth connections for home theaters, gaming setups and professional AV installations. It supports up to 8K at 60 Hz and 4K at 120 Hz according to the manufacturer, offering low-latency, interference-free transmission over extended distances for source devices like PCs and consoles to displays and projectors.
Key Points
The cable uses an optical fiber core to maintain signal integrity over long runs without electromagnetic interference or radiation, and it is engineered for unidirectional transmission with clearly labeled SOURCE and DISPLAY ends. It supports HDMI 2.1 bandwidth ranges up to 48 Gbps, and is backward compatible with older HDMI versions. For gamers, the cable can carry 4K@120Hz with variable refresh rate support for smoother motion and reduced stutter. Handle with care to avoid sharp bends or excessive force on the fiber core, because physical damage can interrupt the signal.
Technical Specifications

Usage Recommendations
Connect the end labeled SOURCE to your signal output such as a Blu-ray player, PS5 or PC, and the end labeled DISPLAY to the TV or monitor. Avoid tight bends, kinks or heavy pulling along the cable length to preserve the fiber core and maintain reliable communication. If no image appears, verify the cable orientation first, then check both device settings and firmware compatibility.
Positive Aspects
Using optical fiber reduces susceptibility to electromagnetic noise and allows long-distance runs that copper HDMI cables struggle with. The support for eARC means enhanced audio return capabilities with compatible receivers and soundbars. Note that the cable is unidirectional, which simplifies installation when properly oriented but means it will not work if reversed.
