HDMI 2.1 Fiber Optic Cable: 4K 120Hz Buying Guide

Need 4K 120Hz video between a distant PC, console or AV rack and your display? A Phoossno HDMI 2.1 fiber optic cable carries high-bandwidth video over a longer route while keeping the cable slim and easy to install.

Is this HDMI active optical cable right for you?

• Home theater and gaming: connect an HDMI source to a TV or projector across the room.
• Conference rooms and digital signage: position playback equipment away from the display.
• Key capabilities: up to 48Gbps, with supported 4K 120Hz and 8K 60Hz modes, HDR and eARC. Confirm the required mode for your chosen model and length.

Four checks before ordering

1. Resolution and refresh rate: the source, display and any receiver or switch must support the target signal. An HDMI cable cannot upgrade a device's capabilities.
2. Installed length: measure the complete route, including bends and service slack. For a 10m, 15m or 20m run, select that length explicitly. Ask Phoossno to confirm longer runs against your resolution and equipment.
3. Signal direction: connect the Source end to the PC, console or player and the Display end to the TV or projector. Test before routing through walls.
4. Installation and audio: check the selected cable's bend radius, jacket rating and eARC compatibility with your TV and audio system.

Why choose fiber optic HDMI?

Optical transmission helps maintain the high-speed video link over distance. This hybrid cable also contains copper conductors, so it should not be specified as a fully electrically isolated connection.

Will a 48Gbps cable deliver every 8K format?

No. Refresh rate, color depth and compression affect the required bandwidth. Confirm the exact video format across the entire system. For certified models, verify the certification label on the selected cable package.
