To those who think there is no "directionality" to 8K cables, think again.
I just installed an 35 foot 8K cable through the baseboard and no, in this case there is no direction (I hope) because the cable is all wire.
But..., some of the 8K cables actually have a module in them that changes the signal to run down a fiberoptic line, and these are directional! And, you also have to be more careful when pulling these cables to avoid breakage.
