How can ultra-fine coaxial cables help autonomous driving cameras achieve high-frequency stable transmission?

In the field of high-speed signal transmission and micro-device interconnection, **micro coaxial cable** has become an important choice for high-frequency interconnection due to its compact structure and excellent shielding performance. With the development of autonomous driving technology, the demand for high-speed image and control data transmission in vehicles has surged dramatically. How to reduce signal loss while maintaining the advantage of small size has become a key issue that engineers must face in system design.

One, achieve high-frequency and high-bandwidth transmission
In an autonomous driving system, the camera is the "visual center," and the extremely thin coaxial cable is the data channel connecting the camera to the central processing unit (ECU).
This type of cable can support extremely high frequency and wide bandwidth transmission, with some design frequencies reaching dozens of GHz, meeting the real-time transmission needs of high-definition video and multi-channel image streams.
For example, the new generation mini high-frequency coaxial connector can support signal transmission frequencies up to 20GHz, ensuring that the autonomous driving system maintains low latency and high stability when processing multi-channel high-resolution images.
Miniaturized structures bring spatial and weight advantages
Compared with traditional FAKRA interfaces, micro coaxial cables have a smaller diameter and lighter weight, offering significant advantages in limited vehicle spaces.
Partial manufacturer's actual test data shows that using the mini coaxial system can save about 80% of installation space.
In the case where cameras are installed in narrow areas such as door panels, rearview mirrors, or the roof, this lightweight and high-density wiring characteristic is particularly important, which can significantly optimize the cable layout inside the vehicle.

Excellent signal integrity and electromagnetic compatibility performance
The extremely thin coaxial cable has precise impedance control (50Ω or 75Ω), which can effectively reduce high-frequency reflections and signal attenuation, maintaining the clarity and stability of image transmission.
Meanwhile, the multi-layer metal shielding structure can resist the complex electromagnetic interference (EMI) inside the vehicle, ensuring signal integrity in high vibration and high noise environments.
This is crucial for core components such as autonomous driving cameras, radars, and perception modules.

Four, advantages of modularized and automated production
Compared with traditional wire harnesses, micro coax has the characteristics of modularization and automated assembly, and can achieve high-efficiency manufacturing in mass production.
The process of automatic peeling, welding, and inspection greatly reduces manual errors, not only improving consistency but also reducing production costs.
This provides more flexible and efficient harness solutions for modern car manufacturing.

Five, intelligent interconnection support for the future
With the continuous upgrading of the vehicle network system, ultra-fine coaxial cables can deeply integrate with communication architectures such as CAN bus, Ethernet, V2X, and OTA, supporting high-speed interconnection and low-latency interaction of vehicle systems.
This scalability makes it an important part of the future intelligent car network, providing solid support for the continuous evolution of advanced driver-assistance systems (ADAS) and autonomous driving functions.

Extremely thin coaxial cable束 in autonomous driving camera systems is no longer just a "transmission medium," but also a crucial link to ensure the efficient and stable operation of the vehicle's visual system.
It is becoming the core trend of intelligent vehicle harness solutions with four advantages: high-frequency transmission capability, space-saving, reliable signal, and production flexibility.
