Product Description
The HDMI Cable 4K Active Optical 20m 60Hz AOC Ethernet HDMI-A Male to Male Black (SKU HDMI-CABLE-4K-20M) links a recorder to a monitor 20m away. AOC means active optical cable. The picture travels as light along OM3 multimode fibre, and copper pairs supply power, so no external power is needed.
What the specs mean for you
- 3840x2160 at 60Hz, 4:4:4 chroma: full 4K at 60 frames per second, with colour kept at every pixel.
- 18Gbps, HDMI 2.0 High Speed, HDR10, 12-bit colour: the bandwidth 4K at 60Hz needs, with high dynamic range and 12-bit colour supported.
- HDCP 2.2: protected content passes through. HDCP is High-bandwidth Digital Content Protection.
- ARC, CEC, EDID, 3D: ARC (Audio Return Channel) returns audio. CEC (Consumer Electronics Control) syncs multiple screens. EDID (Extended Display Identification Data) lets the display report what it accepts. 3D is supported.
- Audio: Dolby TrueHD, Dolby Atmos, DTS:X and 32-channel lossless audio.
- HDMI 1.4 backward compatible: older sources can still connect.
- Unidirectional: the signal runs one way, from source to display.
- Immune to EMI (electromagnetic interference), unlike passive copper.
Fitting it
The cable is 4.5-5mm across and Kevlar-reinforced for conduit runs. Double shielding, including aluminium foil, sits alongside it. It survives 15kg conduit pulls, and pull-eye connectors help. Keep bends to a 45mm minimum radius. Operating range is -20°C to 70°C. The jacket is VW-1 flame-rated PVC. Both ends are gold-plated HDMI Type A male.
What else you need
A recorder (NVR) with an HDMI output, and a monitor with an HDMI input. The picture is only as sharp as the resolution the recorder outputs.
