SMUGDESK 8K Fiber Optic DisplayPort Cable 50M/164FT

SKU CH-MM85-JGSMH

Fiber-optic DisplayPort 1.4 cable carries 8K at 60 Hz and 4K at 144 Hz across 50 metres with 32.4 Gbps bandwidth in a slim, flexible design

Cable Length 164 ft.

  • Transmits true 8K at 60 Hz via DP 1.4 and 32.4 Gbps bandwidth
  • Delivers 4K at 144 Hz and 240 Hz for ultra-smooth gaming visuals
  • Fibre-optic core keeps signal stable over the full 50 m / 164 ft length
  • Slim hybrid glass-and-copper build fits tight spaces and in-wall runs
  • Gold-plated connectors and zinc-alloy shells resist wear and corrosion

50-metre fibre DisplayPort cable

This 50-metre DisplayPort cable uses fibre-optic technology to carry 8K video at 60 Hz and 4K at up to 240 Hz. It conforms to the DP 1.4 standard with 32.4 Gbps bandwidth and is backward compatible with DP 1.2 signals. Gold-plated connectors and a hybrid glass-and-copper construction provide stable long-distance transmission.

Installers needing 164-foot runs

The slim, flexible jacket suits tight conduits and through-wall routing where copper cables would be too bulky. It works with PCs, laptops, Nvidia graphics cards, projectors and HDTVs that have DisplayPort inputs. Buyers whose source and display are only a few metres apart will find a shorter copper cable simpler and cheaper.

Directional connectors and eARC support

One end is marked Source and the other Display; the cable must be installed in the correct orientation. The link carries eARC, HDR10, Dolby Vision and HDCP 2.2 alongside video, so a compatible AV receiver can handle lossless audio without a separate cable. No external power adapter is required for the optical modules.

Questions about this item

What must my graphics card and monitor both support for the 32.4 Gbps link to run at 8K 60 Hz?

Both devices need a DisplayPort 1.4 port that can handle 32.4 Gbps and DSC 1.2 compression; without that the cable will fall back to a lower mode.

If I keep a 1080p or 1440p display on the other end, will the 50 m fibre link still work?

Yes, the cable is backward compatible with DP 1.2 and lower resolutions such as 1080p and 1440p, so older monitors will function normally.

How can I confirm the cable is delivering 8K 60 Hz after I plug it in?

Check your GPU control panel or monitor OSD — it should report 7680×3840 at 60 Hz with HDR or Dolby Vision active if the source sends it.
