About This Item

Wiring a future-proof home theater for an 8K TV or 4K@120Hz gaming monitor mounted 50 to 150 feet from the media rack — and standard HDMI 2.1 copper cables max out at about 10 ft for the full 48 Gbps? Copper HDMI 2.1 just can't hold 48 Gbps over distance. This Ultra High-Speed 8K HDMI 2.1 Fiber Optic AOC carries the full 48 Gbps bandwidth over glass fibers, holding 8K@60Hz and 4K@120Hz signals over runs copper can't reach. UL Listed with a CL3-rated jacket for code-compliant residential in-wall installation. Built with multi-fiber optical construction, gold-plated HDMI connectors, and a CL3-rated PVC jacket. Compatible with PS5, Xbox Series X/S, RTX 30/40 series GPUs, 8K TVs, 4K@120Hz gaming monitors, AV receivers, and any HDMI 2.1 device — directional cable: the SOURCE end must connect to the source device. Supports 8K@60Hz, 4K@120Hz, dynamic HDR (HDR10+, Dolby Vision), VRR, ALLM, eARC at up to 48 Gbps. Best for: in-wall 8K home theater, long 4K@120Hz gaming monitor runs, and PS5/Xbox Series X room-to-room. Not for: plenum spaces (use Plenum AOC) or outdoor exposure. RoHS compliant.
