Questions about this item

What does the 48Gbps bandwidth actually deliver when the cable is connected?

It carries 8K at 60Hz, 4K at 120Hz or 2K at 240Hz with Dynamic HDR, Dolby Vision, eARC, 32 audio channels and 4:4:4 RGB.

How does the HDMI 2.1 interface limit what I can run over the 50ft length?

The 2.1 link caps at 48Gbps, so 8K 60Hz and 4K 120Hz are supported, while older 2.0 or 1.4 sources fall back to their own lower limits.

What do I need to check so the 50ft fiber cable fits and works in my rack?

Allow space for the marked SOURCE and DISPLAY plugs; the cable is slim, flexible and rated for over 20,000 bends, but it only works in the marked direction.
