SMUGDESK DisplayPort 1.4 optical cable 16 ft 8K 60Hz 48Gbps

Optical-fibre DisplayPort cable for 8K at distance

This 16 ft DisplayPort 1.4 optical cable carries 8K 7680x4320 at 60 Hz and 4K at up to 144 Hz with HDR and HDCP support. It is built for users who need lossless video over longer runs between a computer and a display, TV, projector or VR headset. The fibre core avoids the signal degradation that limits copper cables at this length. It targets home-theatre, gaming and workstation-extension scenarios where the source and screen are far apart.

Bandwidth ceiling and directional design

The link tops out at 48 Gbps, which caps 8K to 60 Hz and 4K to 120 Hz; higher refresh rates at 8K are not possible on this standard. Fibre transmission is one-way, so the connectors are marked for source and display ends and must be oriented correctly or no image will appear. Copper auxiliary lines inside the jacket still carry the hot-plug detect and AUX channel, so the link behaves like a standard DisplayPort connection once the direction is right. HDCP 2.2 is supported for protected content playback.

Plug-and-play with a strict orientation rule

Gold-plated connectors and a plug-and-play design mean no drivers or external power are required; the cable draws what it needs from the DisplayPort ports. The only common failure is reversing the ends — installers who ignore the direction labels get a blank screen and often blame a defective unit. Once the source and display ends are matched to the markings, the link is stable and hot-pluggable like any copper cable.
