Wiring an 8K commercial display, conference room 8K wall, or 4K@120Hz simulator above a return-air plenum ceiling — and copper HDMI 2.1 can't carry 48 Gbps past 10 ft, while CL3 fails plenum fire code? NEC requires CMP plenum-rated cabling for return-air spaces, and copper HDMI 2.1 simply doesn't reach the distances commercial AV needs. This Ultra High-Speed 8K HDMI 2.1 Plenum Fiber Optic AOC solves both: glass fibers carry the full 48 Gbps over long runs, and the UL Listed CMP jacket meets NEC code for installation in air-handling spaces. Built with multi-fiber optical construction, gold-plated HDMI connectors, and a UL Listed Plenum CMP-rated jacket. Compatible with PS5, Xbox Series X/S, RTX 30/40 series GPUs, 8K commercial displays, 4K@120Hz simulator setups, eARC 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, VRR, ALLM, eARC at up to 48 Gbps. Best for: commercial 8K above-ceiling installs, 4K@120Hz simulator centers, and high-end conference AV. Not for: outdoor exposure. RoHS compliant.
Wiring an 8K display in a commercial space with a return-air plenum ceiling? NEC 800.179 requires CMP-rated cabling there, and copper HDMI 2.1 can't carry 48 Gbps past 10 ft regardless. Glass-fiber AOC delivers full 48 Gbps over 100+ ft, and UL Listed CMP jacket meets the fire code — both problems solved in one cable.

Carries 8K Ultra HD at 60Hz, 4K@120Hz, dynamic HDR (HDR10+, Dolby Vision), Variable Refresh Rate, Auto Low Latency Mode, eARC for high-bitrate audio, and 4:4:4 chroma sub-sampling. Built for 8K commercial displays, simulator centers, and conference AV.
Compatible with PS5, Xbox Series X/S, NVIDIA RTX 30/40 series, AMD Radeon RX 6000/7000 series, 8K commercial displays, 4K@120Hz simulator/training setups, eARC AV receivers, and HDMI 2.1 media players. Quick check: 150 ft commercial plenum 8K — Yes; residential in-wall — Yes (or use cheaper CL3 AOC); outdoor — No; runs over 150 ft — see longer SKU.
