InLine HDMI AOC cable Ultra High Speed HDMI 8K4K detachable plug 20m

The InLine HDMI AOC cable Ultra High Speed HDMI 8K4K detachable plug 20m is an active optical HDMI 2.1 cable designed for high-resolution video and audio transmission over longer distances. The hybrid construction combines four glass-fibre strands with seven solid copper conductors and offers detachable HDMI A and HDMI D plugs to ease installation through narrow ducts. The cable supports a maximum data transfer rate of 48 Gb/s and resolutions up to 8K@60Hz or 4K@120Hz while maintaining a slim 4.8 mm diameter and robust metal connectors with aramid protection and PVC jacket.

Advantages

The cable provides a 4-in-1 plug configuration (HDMI-D to HDMI-D, HDMI-D to HDMI-A, HDMI-A to HDMI-A, HDMI-A to HDMI-D) for flexible use, gold-plated contacts for improved conductivity and corrosion resistance, and directional signal routing from source to display. As an active optical cable (AOC) it combines fibre and copper to achieve long-distance transmission with lower weight and greater flexibility than pure copper, reduced susceptibility to electromagnetic interference, and no need for an external power supply for optical-to-electrical conversion. It also supports HDMI features such as Dynamic HDR, eARC/ARC, HDCP, EDID, CEC and DDC.

How to use

Determine the required connector combination (HDMI-A or HDMI-D) and attach the appropriate detachable plug ends before threading the cable through narrow ducts. Connect the HDMI plug labelled for the source to the output device (e.g., Blu-ray player, console, PC) and connect the other end to the display or receiver. Ensure proper seating of the metal connectors and avoid sharp bends; the cable is directional, so verify signal flow from source to display. No external power supply is required for normal operation. Follow device menus to enable eARC, HDR or specific audio/video formats if supported.

Usage recommendations

Use the InLine HDMI AOC cable for permanent or semi-permanent installations where high bandwidth, long reach and flexibility are required. Avoid tight coiling and excessive mechanical stress on detachable plugs; maintain operating temperature within the specified range for reliable performance.
