SMUGDESK 8K Optical Fiber DisplayPort 1.4 Cable 10M

10-metre optical DisplayPort cable for 8K

This 10-metre cable uses optical fibre to carry DisplayPort 1.4 signals between a computer and a display. It supports 8K resolution at 60 Hz and 4K at 144 Hz for gaming, home-theatre, VR or extended workstation setups. The plug-and-play design requires no external power or drivers. Gold-plated connectors and a four-core fibre construction aim to maintain signal integrity over the full length.

Distance and bandwidth limits of DisplayPort 1.4

The DisplayPort 1.4 interface caps video bandwidth at 32.4 Gbps, which defines the maximum resolution and refresh-rate combinations this cable can transport. Optical transmission removes the signal-loss ceiling that limits copper cables, so the 10-metre reach does not degrade the 8K 60 Hz or 4K 144 Hz formats. The link is unidirectional from source to sink; reversing the connectors will break the connection. No compression or conversion is applied inside the cable.

Replaces long copper DisplayPort runs that fail

Copper DisplayPort cables typically lose 8K 60 Hz fidelity beyond three metres, forcing installers to add repeaters or accept lower resolutions. This optical assembly eliminates that failure point for 10-metre runs, and the product family extends to 100 metres for larger venues. The upgrade is worthwhile when the source and display both implement DisplayPort 1.4 and the installation distance exceeds reliable copper reach. It does not add bandwidth beyond the 1.4 specification.
