AI Technical Summary
Traditional USB data cables cannot pass through small-aperture environments due to their large end size, and traditional solutions cannot adapt to ultra-small aperture environments while ensuring power supply stability and signal integrity.
The USB data cable adopts a detachable structure, uses fiber optic cable and LC fiber optic connector, realizes signal transmission through LC duplex coupler, and sets up a power supply interface in one USB port. The photoelectric conversion chip realizes the conversion of electrical signals and optical signals.
It achieves complete signal transmission and power supply in a very small space, avoids electromagnetic interference, and requires no additional power supply line, making it suitable for ultra-small aperture environments.
