What Is a Fiber Optic HDMI Cable?

A Fiber Optic HDMI Cable, also known as an Active Optical Cable (AOC), converts electrical signals into optical signals for transmission through fiber optics before converting them back at the receiving end.

Unlike traditional copper cables, Fiber HDMI cables are specifically designed for long-distance, high-bandwidth signal transmission without significant signal degradation.

Typical transmission distances include:

• 10m

• 20m

• 30m

• 50m

• 100m

• 150m

• 200m

• 300m
