I believe you need 12bit for Dolby vision (guys please correct me if I’m wrong)
And both the one I’m looking at and the one you recommend are 10bit.
Wrong, the mistake being to infer from the blurbs that usually come in cable ads that cables “support” features.
They don't
They are simply a medium that a certain amount of data is pushed through.
As such , the bandwidth is all that matters.
Dolby Vision is metadata that is carried in the TMDS data stream. You need a DV capable player and a DV capable screen to get Dolby Vision.
There is nothing you can do to a HDMI cable to make it Dolby Vision or not.
The Same goes for a HDMI fiber cable.
It either has the bandwidth or it doesnt.
Any high speed or premium HDMI cable has enough bandwidth for DV.
The only reason HDMI over fibre exists is because you cannot get HDMI cables over 8 meters to pass the high speed or premium tests.
So any fibre cable should do.
Pay no attention to the features listed in HDMI cable ads.
They are largely nonsense.
The only things that bear any resemblance to the truth are bandwidth figures, or in the case of conventional HDMI cables, whether it is “ standard” , “ high” or “ premium” speed.
You are on a wild goose chase looking for a “12 bit” or “10 bit” fibre cable.
Technically, that is nonsense, the cable sellers being at fault here for their dishonest and misleading ads.
