The Real Cable HD-OPTIC 8K HDMI cable is an HDMI 2.1 optical cable designed to deliver top-notch visual and audio performance for home theater installations or gaming setups. It supports ultra-high definition resolutions and refresh rates, ensuring compatibility with the latest media devices and content.
The HD-OPTIC 8K features the HDMI 2.1 standard, allowing it to support bandwidth up to 48 Gbps. This characteristic is crucial for transmitting 8K content at 60 Hz or 4K at 120 Hz without signal loss. The cable is made from high-quality materials, including 24K gold-plated contacts for enhanced conductivity and corrosion resistance. Its construction includes double shielding, protecting against electromagnetic interference and ensuring pure, unaltered signal transmission.
The available length of this cable varies, offering options up to 20 meters without compromising signal quality. This feature makes it particularly suitable for installations requiring long cable runs, such as home theater rooms or professional setups.
When installing the HD-OPTIC 8K cable, it is important to ensure that the source and display ends are properly connected, as the cable is unidirectional. The source end should be plugged into the HDMI output of devices such as Blu-ray players, gaming consoles, or streaming devices, while the display end connects to the input of a TV or projector.

Good quality cable material, it’s quite flexible, and the connectors also seem reliable to me. The picture is excellent on my Sony xw5000 projector.
