Graphite 8K HDMI 2.1 Active Optical Cable

A graphite-finished HDMI 2.1 active optical cable for 8K display links. The two ends are marked Source and Display, so you can see at a glance which way round it goes. The signal runs over fiber for the long stretch, which keeps it steady over distances where copper starts to struggle.

This is the graphite version of our 8K HDMI 2.1 active optical cable. The housings are a dark graphite grey, and each end is printed with its job — one end says Source, the other says Display, and the source end is also marked 8K. That matters, because this cable only works one way round. Plug the Source end into your player, console or PC, and the Display end into the TV or projector. Inside, the video travels over fiber for the long part of the run, with copper handling the control signals. That is what makes it useful for long runs — from a rack at the back of the room to a screen on the far wall, or from a media cupboard to a projector on the ceiling. A long copper HDMI cable can drop the picture at 8K. Fiber does not have that problem.

A note on the numbers: the housings are marked 8K, and the source material lists versions rated up to 48 Gbps, 8K at 60 Hz and 4K at high refresh rates. Those figures only apply to the validated cable version, used with HDMI 2.1 source and display equipment that supports them. Cable length is not stated in the source material — confirm the length you need before ordering. The connectors are standard HDMI Type-A plugs with gold-plated contacts. No extra power supply is mentioned in the source material, so check the power requirements for your setup and cable length.

  • Housing marking visible in the photo: “8K” on the source end, “HDMI” and “Display” on the display end
  • Signal path: hybrid optical (active optical conversion for the long segment)
  • Version-dependent performance (source TXT, conditional): versions rated up to 48 Gbps, 8K at 60 Hz and 4K at high refresh rates — only with compatible HDMI 2.1 equipment and the validated cable version

  • 8K / high-refresh performance depends on the source, the display and the validated cable version all supporting it.

Application Scenarios

  • 8K display links in home theater
  • 4K high-refresh gaming setups
