8K HDMI 2.1 Fiber Optic Cable – Proven 48Gbps Performance

An 8K HDMI 2.1 fibre optic cable solves a problem copper cables can’t: distance. Standard copper HDMI cables start losing signal integrity past 5- 8 m, but the DTECH DT-HOF8010 uses active optical (fiber) technology to carry the full 48Gbps HDMI 2.1 bandwidth over runs of up to 300m — with zero signal degradation, no repeaters, and no extenders required.

Why Choose This 8K HDMI 2.1 Fibre Optic Cable

Unlike copper HDMI cables, which rely on electrical signalling that weakens over distance, this cable transmits data as light through four multi-mode optical fibres. That means:

• Full 48Gbps bandwidth maintained at any supported length — no drop-off at 50m that you’d get with copper
• 8K@60Hz, 4K@120Hz, and 2K@144Hz resolution and refresh rate support
• 12-bit colour depth with static HDR and Dynamic HDR10+ for accurate, scene-by-scene brightness and colour
• 3D content support for compatible source and display combinations
• EMI-free transmission — immune to the electromagnetic interference that causes signal noise in long copper or in-wall runs

Built for Long-Distance and In-Wall Installations

At just 4.8mm in diameter, this cable is noticeably thinner and more flexible than a comparable copper HDMI cable, which makes it easier to fish through conduit, wall cavities, or ceiling runs during a professional AV install. It supports hot-swap connections and is rated for pre-embedded (in-wall) installation, so it can be run once during construction or renovation and left in place — no extenders, baluns, or signal amplifiers needed at any point along the run, even at the longer lengths.

Broad Compatibility

This cable is backward compatible with HDMI 2.0, 1.4, 1.3, 1.2, and 1.1 devices, so it works whether you’re connecting the newest 8K source and display or pairing an older HDMI 1.4 Blu-ray player to a projector three rooms away. On older HDMI sources or displays, it simply runs at that device’s native speed — the cable itself isn’t the bottleneck. It’s built to the HDMI 2.1 specification set by the HDMI Forum, which is what guarantees the 48Gbps bandwidth and 8K/4K120 support across compliant devices.

Length Options: 1m to 300m

Available lengths: 1m, 2m, 3m, 5m, 8m, 10m, 15m, 20m, 25m, 30m, 40m, 50m, 60m, 100m, 200m, and 300m. That range covers everything from a short desktop-to-monitor run to a full commercial installation — a projector at the back of a conference room, a video wall fed from a rack in another part of the building, or a home theater with the source components in a separate equipment closet.

Who This Cable Is For

• AV integrators and installers running HDMI over long in-wall or in-ceiling distances without adding extenders or baluns to the budget
• Commercial and conference room setups where the display and the source equipment (media player, PC, switcher) sit far apart
• Home theatre installations with equipment racks located away from the screen
• Anyone who tried a long copper HDMI run and got a flickering or blank picture — the usual sign that copper has hit its distance limit for the bandwidth being pushed

Frequently Asked Questions

What’s the difference between this and a standard copper HDMI cable? This cable transmits over optical fibre instead of copper wire, so it holds full 48Gbps bandwidth at lengths far beyond what copper can manage — up to 300m versus roughly 8m for a good copper cable. If you only need a short run under 8m, our DTECH 8K HDMI 2.1 copper cable is a lower-cost option.

Does this cable have a direction — a source end and a display end? Many active optical HDMI cables are directional, with the connectors marked for the source (player, console, PC) and display (TV, projector, monitor) ends. Check the connector housings for an arrow or “IN/OUT” label before installing, and connect accordingly.

Can I use it for in-wall or in-ceiling installation? Yes. It’s rated for pre-embedded installation and its 4.8mm diameter makes it easier to pull through conduit or wall cavities than a comparable copper cable.

Does it need a power source or extender at longer lengths? No. It’s a self-contained active optical cable — no external power, extenders, baluns, or amplifiers are needed at any supported length.
