Key features:

1. Lossless Long-Distance Transmission Zero Delay: Uses optical fiber to convert electrical signals into light, allowing for lossless transmission of $4\text{K}@60\text{Hz}$ video over 50 meters with no delay or attenuation.

High Resistance to Interference: The fiber optic nature provides High EMI/RFI resistance (Electromagnetic/Radio Frequency Interference), making it ideal for use near other electronics, in data centers, or in pre-buried engineering installations.

2. Supported Technologies HDCP 2.2: Essential for securely transmitting protected 4K content (e.g., from Netflix, 4K Blu-ray players).

ARC (Audio Return Channel): Allows audio to be sent back from the TV/Display to an AV receiver or soundbar via the same HDMI cable.

Dynamic HDR Support: Some versions may support Dynamic High Dynamic Range (HDR) for improved contrast and color.

3D Content: Supports 3D visual effects.

. Build Quality Slim and Flexible: Optical fiber cables are generally thinner and more flexible than heavy-gauge copper cables required for $4\text{K}$ transmission over short distances. Plug Housing: Features gold-plated connectors and often a zinc alloy shell for stable signal conductivity and durability.
