There are optical HDMI cables with much longer maximum lengths than passive copper cables. I assume the electrical - optical conversion is done in the plug itself.

Squizzy@lemmy.world 9 months agoHave you had any issues, I’m seeing ridiculously long cables that I didn’t think we’re commercially available like 15m 48gbps HDMI which I thought was above the length maximum

That is unbelievable, I never knew this. I can’t believe there is a terminal in the jack allowing for the conversion it’s really impressive.

Is it fiber or copper? Copper is probably not going to get you that far, but fiber can supposedly still deliver a decent signal at up to 60m.

I don’t understand, wouldn’t the cable need to be copper to be a HDMI? If it was fiber you’d need something to convert the signal back to electrical from optical before the TV no?

There are HDMI cables that are basically HDMI to fiber tranceivers. The HDMI plug draws power from the HDMI port to use active components to convert to a fiber signal.
