8K HDMI Fiber Optic Cable 10 ft CL2 Rated - 48Gbps HDMI 2.1

Our review of this 8K HDMI fiber optic cable focuses on who will benefit most and the single biggest reason to buy: uncompromised HDMI 2.1 performance over a thin, CL2 in-wall rated cable. For anyone connecting a high-end PC GPU or next-gen console to a TV, projector, or AVR and needing full 48Gbps bandwidth, this cable delivers 8K@60Hz and 4K@120Hz support with Dynamic HDR and eARC. The review found consistent signal integrity at long runs and the reassurance of in-wall CL2 safety makes it a practical choice for permanent installs.

Key Features

• 8K@60Hz and 4K@120Hz: Enables the latest high-frame-rate video modes so gamers and media lovers can use 4K120 or 8K60-capable displays without downscaling.
• 48Gbps bandwidth: Supports the full uncompressed HDMI 2.1 data pipe for HDR and high-refresh content, reducing the risk of compression artifacts.
• Fiber optic construction: Maintains signal quality over longer runs compared with copper, helping avoid dropouts with demanding resolutions.
• eARC support: Passes high-bitrate object-based audio to AV receivers for immersive formats like Dolby Atmos and DTS:X.
• CL2 in-wall rating: Adds safety and code compliance for routing the cable inside walls for home theater installations.
• Broad compatibility: Works with modern GPUs and consoles and is backward compatible with older HDMI versions for flexible use.

Who It's For

This cable is aimed at homeowners and enthusiasts installing or upgrading a dedicated home theater, gamers with RTX 40-series and 30-series GPUs or current consoles who need reliable 4K120 or 8K60 performance, and AV installers who require CL2-rated in-wall cabling. It is also a good fit for those who want eARC to pass advanced audio from TV apps to an AVR.

Those who only use short runs, older 1080p displays, or do not need eARC and high refresh rates may find less value here; a cheaper copper HDMI cable can suffice for simple, short connections.
