Review on Phoossno Certified 8K Fiber Optical HDMI 2.1 Cable - Ultra High-Speed 48Gbps 33ft 10m - HDR eARC HDCP2.2 2.3 Support - 4K 120Hz, 8K60Hz - Compatible with PS5, Xbox, TV, Monitor, PC by Brockington Zuniga

I believe this is only the second 15m HDMI certified UHS cable on the market. Connected to HDMI 2.1 8K video processor with installed 3080 GPU and HDMI 2.0 4K projector. Works as described on the website. The source end connector feels a little warm, but phoossno support told me that this is normal as the power consumption at the source connector is 5V, 140mA @ 8K @ 60Hz and 4K @ 120Hz, and the zinc alloy material , for which they are used connector housings dissipate heat effectively. They also informed me that according to their tests, the temperature of the cable head at the source end is within 50°C (maximum) depending on the connector chipset used, and that the lifetime according to the specification for that chipset is 100,000 hours. seems knowledgeable.
