fiber optical hybrid HDMI 2.1 cable
"Slim outer cable diameter 4.84mm (±0.2mm) makes the cable easy to hide versus bulky all copper cables. Four tiny hair-size fiber optical cables carry the main signal while the remaining voltage and other signals pass through small copper cables. This makes the cable thin, flexible, and easy to hide. "
