AI System High-Speed Signal Stability Guide: Why Use Micro Coaxial Cables

In high-speed devices such as AI systems, camera module groups, and visual processing board cards, the signal transmission rate of MIPI interfaces is increasingly high, which also raises the performance requirements for cables. The extremely thin coaxial cable束 (micro coaxial cable) with its excellent signal integrity, shielding performance, and flexibility, has become almost an indispensable high-speed signal transmission solution in these systems. Understanding its advantages helps engineers choose the most suitable cable solution in design.

Signal integrity and anti-interference capability

MIPI interfaces commonly reach speeds from several hundred Mbps to several Gbps. Insertion loss, reflection, crosstalk, and jitter on the line will directly affect signal quality. Extremely thin coaxial cables are composed of a central conductor, insulating medium, and outer shielding layer, which can stabilize characteristic impedance, reduce reflection and crosstalk, and maintain a clear signal eye diagram with low error rate. Compared with ordinary FFC or ribbon cables, extremely thin coaxial cables exhibit more reliable signal integrity under high-frequency and high-speed conditions.

Spatial adaptability and mechanical flexibility

AI module, camera module, drones, robots, and other equipment have limited internal space, so cables need to be small, light, and flexible. The diameter of ultra-fine coaxial cable bundles is typically only a few hundred micrometers to 1 millimeter, making the wiring flexible and easy to arrange in compact spaces. They have high mechanical strength, strong anti-interference capability, and are more suitable for applications involving frequent bending and path turns than traditional ribbon cables.

Section 3: Standard Compatibility and Transmission Performance

There are already several manufacturers providing micro-coaxial cable solutions that support high-speed protocols such as USB, eDP, MIPI, PCIe, such as I-PEX CABLINE series, which facilitate the reuse of design experience between different modules and reduce the complexity of debugging. In short-distance transmission, the extremely fine coaxial cable has low attenuation and stable impedance, combined with reasonable termination matching and cable length control, which can ensure stable transmission of high-speed signals and avoid errors and dropped frames.

The MIPI interface chooses extremely fine coaxial cable束 in AI systems because it is superior to other cable solutions in multiple dimensions such as signal integrity, interference resistance, size flexibility, standard compatibility, and transmission performance. For applications that pursue high speed, low error rate, and high reliability, micro coaxial cables are the optimal solution in engineering.
