BZBGear BG-CAB-H21A 8K HDMI 2.1 Active Optical Cable

The BG-CAB-H21A is an active optical HDMI 2.1 cable: the signal travels on fiber inside the jacket, which is what makes 48 Gbps possible at lengths a copper HDMI cable cannot reach. It carries 8K at 60 Hz and 4K at up to 120 Hz with HDR.

The HDMI 2.1 feature set travels with it, including variable refresh rate, auto low latency mode, quick media switching and quick frame transport, so it is as much a games console cable as a rack cable. It is directional, like all active optical cable, so the source and display ends are marked. Lengths run from 10 m to 100 m.
