## Description

This fiber optic HDMI cable is built to deliver high-bandwidth video and audio over longer distances with less signal loss, perfect for home theaters and gaming setups where the source is separated from the display. If you need a reliable fiber optic HDMI cable 5m for 8K or high-frame-rate gaming, this model supports higher refresh rates and enhanced audio features while remaining thin and flexible for easier routing.

## Key Points

The cable supports up to **48Gbps** bandwidth and handles 8K@60Hz and 4K@120Hz, which makes it suitable for next-generation consoles and UHD sources. It adds eARC support for higher quality audio and includes features like Dynamic HDR and Dolby Vision compatibility according to the manufacturer. The slim fiber design reduces electromagnetic interference and offers greater bend resistance compared with traditional copper cores, which helps in tight installations and runs behind furniture.

This cable is unidirectional, so the SOURCE end must be connected to the video output device and the Display end to the TV or monitor. Pay attention to the connectors during setup to avoid a blank screen. The construction includes gold-plated connectors and a zinc-alloy shell for corrosion resistance and durability. For gaming, support for VRR, ALLM, QFT, QMS, and DSC helps reduce tearing and input latency, resulting in smoother motion during fast-paced titles 🎮. The cable also supports up to 32 audio channels and 4:4:4 RGB color sampling for accurate color reproduction and immersive sound.

## Technical Specifications

- Name: **RUBMUD 8K HDMI 2.1 Cable 15ft/5m**
- Bandwidth: 48Gbps
- Supported resolutions: 8K@60Hz, 4K@120Hz, 2K@240Hz

## Usage Recommendations

Route this thin fiber cable through narrow pathways or behind wall trims where thicker copper cables are impractical. For best results, verify the orientation markings on each connector before powering devices. If your setup uses older HDMI hardware, the cable remains backward compatible but advanced features like 4K@120Hz or eARC depend on both source and display supporting HDMI 2.1 functions. Consider labeling both ends during installation to simplify future maintenance.

## Advantages

Compared with conventional copper HDMI cables, the fiber construction offers lower attenuation over distance and can achieve lossless transmission over much longer runs according to the manufacturer, potentially up to hundreds of meters in optimal conditions. The cable is rated for more than 20,000 flex cycles and includes a two year warranty for manufacturing defects. It is plug and play with no external power required, and works with consoles, Blu-ray players, PCs, projectors, and UHD streaming devices. 📺🎧.
