SyncWire HDMI 2.1 Active Optical Cable - 15 m - 20 m

Description

HDMI 2.1 Active Optical Cable for Long Full-Bandwidth Runs

Past ten meters or so, a passive copper HDMI cable can no longer reliably sustain the 48 Gbps of the HDMI 2.1 spec. The SW-HDMI-8K-AOC uses a hybrid design: optical fiber carries the audio-video signal over the length, while copper conductors carry the power that feeds the electrical-to-optical conversion modules built into each plug. Because fiber is immune to electromagnetic interference, the signal crosses a full room without degradation, without an external amplifier, and without an extender box.

Full HDMI 2.1 Feature Set and In-Wall Certification

The cable supports the full HDMI 2.1 feature set: 4K at 120 Hz with 4:4:4 chroma, 8K at 60 Hz, dynamic HDR (HDR10+, Dolby Vision), enhanced Audio Return Channel (eARC) for Dolby Atmos over Dolby TrueHD and DTS:X, HDCP 2.3, plus VRR and ALLM for PlayStation 5, Xbox Series X, and a compatible PC. The jacket carries c(UL) FT4 certification for in-wall or in-ceiling installation under building code. The HDMI plugs are directional and clearly marked Source and Display.

Common Questions

Why choose this product?

The SW-HDMI-8K-AOC is the cable to pick for a long run (15 or 20 m) that must keep every HDMI 2.1 feature — 4K at 120 Hz, 8K, dynamic HDR, eARC, VRR, ALLM. Fiber avoids the bandwidth loss a passive copper cable would take at that distance, and power comes straight from the HDMI port with no external brick. It is the clean answer for running from an AV receiver to a rear-of-room projector or to a display in another room.

Is the cable directional?

Yes. Active optical cables carry different conversion modules at each end and must be installed the right way around. The plug marked Source connects to the device sending the signal (AV receiver, Blu-ray player, game console, PC), and the plug marked Display connects to the television or projector. Wired backwards, no picture reaches the display.

Do I need an external power supply?

No. The optical-electrical conversion modules run on 5 V drawn from the HDMI port on the source device. No wall outlet or external adapter is needed. If an older source shows a power issue at plug-in, flipping the cable orientation or trying a different source usually resolves it.
