20 m optical DisplayPort 1.4 cable

This 20 m DisplayPort 1.4 cable uses optical fibre to carry 8K at 60 Hz or 4K at 144 Hz over long distances. It supports HBR3 bandwidth of 32.4 Gbps, HDCP 2.2 and DSC 1.2 for HDR content. The directional design has labelled Source and Display ends that must be connected correctly. It suits gaming monitors, home theatre, professional office and VR setups.

Replaces copper cables that lose signal at length

Standard copper DisplayPort cables often fail to maintain 8K or high-refresh 4K beyond a few metres. This optical link delivers stable 32.4 Gbps transmission at 20 m without signal loss. The upgrade is worth it when the source and display are far apart, such as projector installations or cross-room PC-to-monitor runs. Shorter 10 m or 33 ft copper alternatives may suffice for closer setups.

Verify port direction and device compatibility

Ensure the Source connector plugs into the GPU, laptop or other DP output and the Display connector plugs into the monitor, TV or projector; reversed ends will give no picture. Confirm both devices support DisplayPort 1.4 with HBR3, HDCP 2.2 and DSC 1.2 to use 8K 60 Hz or 4K 144 Hz. The cable is plug-and-play once oriented correctly.

Questions about this item

Will the 20 m optical fibre cable fit through standard conduit or trunking?

The cable uses a thin optical fibre core with standard DisplayPort connectors at each end, so it passes through typical conduit sizes used for video cables.

What is the correct way to plug in the directional Source and Display ends?

Connect the end marked Source to the computer or laptop DP output and the end marked Display to the monitor, TV or projector; reversing them will give no picture.

Does the cable require any periodic cleaning or module replacement over time?

No, the fibre-optic link is sealed inside the jacket and has no user-serviceable parts; it is designed to last the life of the installation.
