UGREEN 80406 HDMI 2.1 Fibre Optic Cable 10 m, 8K 60 Hz, 48 Gbps

Overview

The UGREEN 80406 is a 10 m HDMI 2.1 cable that sends the signal over optical fibre instead of copper, so it can run from a console, PC, media player or AV receiver to a projector, wall-mounted TV or meeting room screen far across the room. It carries up to 48 Gbps, enough for 8K at 60 Hz or 4K at 120 Hz when the source, the display and anything between them support those modes. It is directional: the plug marked Source goes to the sending device and the plug marked Display goes to the screen.

Is it right for you?

• It suits a run where a passive copper HDMI cable would be too short: the route must genuinely need 10 m, with enough slack but no tight coil or tension.
• Because it is directional, you need to know which device sends and which receives before pulling the cable through a wall or ceiling.
• Both HDMI ports must support the mode you want. The cable cannot add a resolution, refresh rate, eARC or an HDCP version to a port that lacks it, and earlier HDMI equipment works at its own lower mode.
• Every adapter, receiver, switch, splitter, wall plate or extra cable in the path must support the same video, HDCP and audio requirements.

Key features

• 48 Gbps HDMI 2.1 bandwidth, for up to 8K at 60 Hz or 4K at 120 Hz on supporting equipment.
• Passes Dynamic HDR, HDR10 and Dolby Vision (high dynamic range) for brighter, higher-contrast pictures from compatible content.
• Enhanced audio return channel (eARC) and multichannel audio formats pass through when the TV and the soundbar or receiver support them.
• Fibre optic transmission keeps the signal intact over the full 10 m, keeps the cable flexible and resists electromagnetic interference (EMI).
• Active electronics powered from compatible HDMI ports: no separate power adapter.

What else you need

A source with a full-size HDMI output and a display, projector or receiver with a full-size HDMI input. The active electronics are powered through the HDMI ports, so no separate power adapter is needed, and there is no driver or software to install. It does not convert USB-C, DisplayPort, Mini HDMI, Micro HDMI, DVI or VGA.

Installation

For a run through walls, ceilings or conduit, an AV installer should fit it. The job is to confirm the Source and Display ends before routing, pull the cable along a route with gentle curves and no crushing, plug the Source end into the HDMI output and the Display end into the HDMI input, and test the picture and sound at the intended resolution before the route is closed up. For a run along a skirting or behind furniture, you can plug it in yourself, keeping the direction right.

Before you buy

• The 8K at 60 Hz and 4K at 120 Hz figures are cable ceilings, not guaranteed modes. The source, display, content, firmware and settings decide what you actually get.
• It does not work in reverse. If the Source and Display ends are swapped there will be no picture.
• It is not a passive copper cable: it cannot be cut, shortened or re-terminated, and it does not upscale content, create HDR, decode audio or generate frames.
• No in-wall or concealed-route safety rating is stated for this cable, so do not rely on one.
• Check that the cable you receive is marked 80406 and 10 m.
