Detachable HDMI Fiber Optic Cable – 8K@60Hz, 48Gbps DTECH DT-HF3000

This detachable HDMI cable solves a specific installation problem: a finished HDMI connector is often too wide to pull through conduit, wall cavities, or pre-buried pipe. The DTECH DT-HF3005 ships with its connector heads detached from a slim pass-through cable end, so you feed the bare cable through the tight space first, then attach the full-size HDMI (Type A) connector heads on both ends once it’s through. The result is a normal, complete HDMI connection at both ends — the detachable design only matters during the pull.

How This Detachable HDMI Cable Works

A finished HDMI plug is bulkier than the cable itself, which is exactly what makes it hard to fish through narrow conduit, trunking, or a pipe already set into a wall. The heads on this detachable HDMI cable clip on and off by hand, no tools required, so the pass-through cable stays slim enough for conduit down to 0.65″ inner diameter during the pull — then you clip the HDMI heads on afterward, at the source and display ends, once the hard part is done.

Fiber Optic Core for Long, Loss-Free Runs

Unlike a plain copper HDMI cable, this cord combines a fiber optic core with copper conductors, carrying the full 48Gbps HDMI 2.1 signal over long distances without the signal degradation that limits all-copper cables. That means 8K@60Hz, 4K@120Hz, and 2K@144Hz stay stable even on runs long enough that a standard cable would drop frames or lose the signal entirely.

Built for In-Wall, In-Ceiling and Conduit Installs

Because the connector heads detach, this cable handles exactly the runs a finished-head cable can’t: through wall conduit, behind trim, inside cable trays, or through pipe pre-buried between rooms or floors. An installer feeds the slim cable end through first, then attaches the HDMI heads at the source and display ends once the run is complete.

Immersive Audio Through eARC

The enhanced Audio Return Channel carries lossless Dolby Atmos, DTS:X, Dolby TrueHD, and DTS-HD Master Audio, with support for 5.1 and 7.1 multi-channel sound — useful when the same cable run also needs to send audio back to an AV receiver or soundbar.

Slim, Pull-Resistant Build for Conduit Routing

At just 4.8mm in outer diameter, the pass-through cable threads through conduit with a minimum inner diameter of 0.65″. The copper-core aramid-yarn construction adds pull strength for the fish-through without adding bulk, and the gold-plated, zinc-alloy connector heads resist corrosion and repeated plugging once attached.

FAQ

Why does the connector detach? A finished HDMI plug is too wide to pull through most conduit or pre-buried pipe. This cable ships with the heads detached from a slim pass-through cable end, so you can feed it through the tight space first and attach the full-size HDMI connectors afterward.

Is the reattached connector as reliable as a factory-terminated head? Yes — the heads clip on and off by hand, no tools required, and are designed to be fitted on-site as part of normal installation, not a repair or workaround. Once clipped on, it’s a standard, complete HDMI Type A connection at both ends.

What’s the minimum conduit or pipe size this fits through? The pass-through cable end is rated for conduit with an inner diameter as small as 0.65″.

Does the fiber optic core need external power? No. It’s plug and play, with no batteries or power adapter required.

Why fiber optic instead of plain copper for this kind of install? On long in-wall or in-ceiling runs, an all-copper HDMI cable at 48Gbps can lose signal integrity and drop frames or resolution. The fiber optic core carries the full 8K/48Gbps signal over much longer distances without that loss — useful exactly where conduit runs tend to be long.
