Have 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

    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.

    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?
