DELONG Fiber Optic HDMI Cable 100ft - Slim 4K@60Hz Long Reach

In this review the DELONG Fiber Optic HDMI Cable 100ft is assessed for people who need a long, reliable HDMI run without signal degradation. The bottom line: this slim fiber HDMI cable is best for home theater installers, classrooms, and conference rooms that require 4K@60Hz UHD over long distances; its single biggest advantage is delivering 4K@60Hz 18Gbps performance with minimal bulk so it slips through walls and conduit easily. The reviewer found it functional, easy to use, and notably thinner and lighter than traditional copper HDMI runs.

Key Features

• Ultra high speed: Supports up to 18.2Gbps so 4K@60Hz UHD content plays without obvious signal loss or downscaling.
• Slim and lightweight: At roughly 4.8mm diameter the cable is significantly thinner than copper alternatives, making in-wall wiring and tight routing simpler.
• Broad format support: Handles HDR, Dolby Vision, ARC, CEC, EDID and HDCP 2.2 for wide compatibility with modern sources and displays.
• Audio and sync: Supports up to 32-channel uncompressed audio and 1536kHz sample rates for stable audio/video sync in AV setups.
• Plug and play: No external power required and the cable is ready to use with laptops, consoles, Blu-ray players and projectors.
• Long-distance option: The 100ft length is suited to large rooms or runs between equipment racks and wall displays.

Who It's For

This cable is aimed at AV installers, home theater enthusiasts, schools and businesses that need to carry 4K HDR video over long distances without bulky cable. The slim profile helps where wall or ceiling routing is required and the plug-and-play nature keeps installation straightforward for general users.

It is less suitable for users who need a bidirectional active extender solution, or those who require proprietary locking connectors or very high bandwidth beyond HDMI 2.0b limits. If you need HDMI 2.1 bandwidth, variable refresh rate features, or integrated power for repeaters, look elsewhere.

Pros & Cons

Pros

• Delivers consistent 4K@60Hz and HDR playback across a 100ft run with no external power.
• Slim 4.8mm diameter makes pulling through walls and conduits much easier than thick copper cables.
• Wide compatibility with TVs, projectors, game consoles and computers for versatile installs.
• Good value and perceived build quality from customer feedback for long runs.

Cons

• Limited to HDMI 2.0b bandwidth (up to 18Gbps), so it does not support HDMI 2.1 features like 4K@120Hz or higher VRR bandwidth.
• The cable is single-way fiber optic; installers must confirm orientation before final installation.
