What this cable does

This 25 metre fiber optic HDMI 2.1 cable carries 8K video at 60 Hz and 4K video at 120 Hz with a 48 Gbps bandwidth ceiling. It is built for installers and home-cinema owners who need long-distance, loss-free runs to a projector, HDTV or AV receiver without signal degradation.

Installation notes

Detachable heads let the slim fiber pass through tight conduit or small drilled holes before the connectors are reattached, making in-wall routing practical. The optical design eliminates electromagnetic interference, but the cable is directional — source and display ends are marked and must be connected the right way round or no picture will appear.

Check before ordering

Verify that your source device and display both have HDMI ports and can negotiate HDMI 2.1 features such as 8K60, 4K120, VRR, eARC and HDCP 2.3 if you need them. The link is backward compatible with HDMI 2.0, 1.4, 1.3, 1.2 and 1.1, so older gear will still work at its native limits. Ensure the 25 metre length matches the exact run you measured; the cable cannot be cut or spliced.

Questions about this item

How can I confirm the cable is delivering 8K at 60 Hz or 4K at 120 Hz after connecting it?

Check the display settings on your PS5, Xbox Series X, Nvidia 3080 or 3090 to verify 8K 60 Hz or 4K 120 Hz output, and confirm HDR or Dolby Vision is active in the on-screen menu.

What comes in the box and is a separate power adapter required for the 25 metre length?

The cable includes detachable heads for easy through-wall routing; no external power supply is mentioned, so the HDMI source powers the optical converters.

Which HDMI version should I select if my display only supports HDMI 2.0?

The cable is backward compatible with HDMI 2.0, 1.4, 1.3, 1.2 and 1.1, so it will work at 4K 60 Hz or 1080p without any setting changes.
