Why do optical fiber HDMI cables contain electronic chips?

The presence of electronic chips in optical fiber HDMI cables can be attributed to the following reasons:

Signal Conversion: Optical fiber HDMI cables transmit data using light signals, whereas HDMI devices operate using electrical signals. The electronic chips convert electrical signals into light signals for transmission, and then back into electrical signals at the receiving end to ensure proper decoding and usage of the data.

Performance Enhancement: The electronic chips support high-resolution and high-refresh-rate transmission requirements, such as 4K at 60Hz or higher standards, providing a stable and smooth audiovisual experience.

Interference Resistance: Optical fiber offers resistance to electromagnetic interference, and the electronic chips further correct and optimize the signal, reducing signal loss or interference during transmission.

Multi-Functionality: Some optical fiber HDMI cables perform complex tasks, such as managing control signals or enabling stable long-distance transmission, which require the assistance of electronic chips to achieve.

In summary, electronic chips are indispensable components within optical fiber HDMI cables. They integrate optical and electronic technologies to deliver efficient and high-quality audiovisual transmission.
