DELONG Fiber HDMI 2.1 Cable 100ft - Slim 8K/4K High-Speed

Our review finds the DELONG Fiber HDMI 2.1 Cable 100ft is aimed at anyone who needs a long, reliable connection for high-resolution gaming or home theater without the bulk of copper cables. The bottom line: this cable delivers clean, long-distance transmission up to 8K@60Hz and 4K@120Hz with a slim 4.8mm diameter that makes routing and concealment much easier than thick copper HDMI alternatives. It is a straightforward, plug-and-play option for PS5, Xbox, high-end GPUs and 8K TVs where signal integrity over distance is the primary concern.

Key Features

• Long distance 8K video: Supports 8K@60Hz and up to 10K resolution for reliable transmission over 100ft without noticeable signal loss.
• High bandwidth: 48 Gbps capacity handles high frame rates and deep color, enabling 4:4:4 RGB and 12-bit color for accurate image reproduction.
• Slim, lightweight design: 4.8mm diameter fiber core is up to 60 percent thinner and lighter than traditional copper HDMI cables for flexible wiring and easier concealment.
• Modern HDMI features: Backward compatible and supports eARC, ALLM, VRR, QFT, QMS and Dynamic HDR10 for gaming and home theater compatibility.
• No external power required: Fiber optic construction eliminates the need for an external power supply while keeping output stable for long runs.

Who It's For

The DELONG 100ft fiber HDMI cable is best for gamers using PS5, Xbox, or high-end GPUs like RTX 3080/3090 who need long runs from console or PC to a distant display and demand 4K@120Hz or 8K capability. It is also a good choice for home theater installations where maintaining signal quality across a long distance is more important than low cable cost.

Those who should look elsewhere include buyers who need ultra-low-cost short cables, or users who require fully passive copper cables for certain legacy AV equipment where fiber termination or compatibility might be an issue; this product is focused on modern HDMI 2.1 device compatibility.
