8K Certified HDMI 2.1 Cable

This Keyence cable delivers 48Gbps bandwidth for uncompressed 8K video at 60Hz and 4K at 120Hz. It supports Dynamic HDR, Dolby Vision and eARC for object-based audio formats. The CL2 in-wall rating makes it suitable for permanent installation behind walls. It is built for home-theatre enthusiasts and installers who need certified 8K performance over a 15-foot run.

Thermals noise and power draw

As a passive copper cable it generates no heat, produces no noise and draws no external power. The 30AWG conductors handle the 48Gbps signal without active circuitry. There are no fans, pumps or power adapters to consider. The cable simply transmits the signal between compatible source and display devices.

Sustained load behaviour

The Ultra High Speed HDMI certification guarantees reliable 48Gbps throughput for extended viewing sessions. DSC 1.2a allows visually lossless 10K at 120Hz when source and sink support it. Signal integrity is maintained across the full 15-foot length without dropouts or artefacts. It is not intended for runs longer than 15 feet or for users who need active optical extension.

Questions about this item

How do I install this 15-foot CL2-rated cable in a wall, and what step is often missed?

Route the cable through studs, secure it with low-voltage brackets, and verify the CL2 marking faces the inspector — skipping the inspection step fails code.

Will the 30AWG conductors or connectors need replacement after years of 48Gbps use?

The cable is passive; no internal components wear out. Only physical damage to the jacket or bent pins would require a new cable.

At what point does the 48Gbps bandwidth limit appear during sustained 8K@60Hz or 4K@120Hz playback?

The 48Gbps ceiling is the first limit; content exceeding it requires DSC 1.2a compression to remain stable.
