The analysis of high-speed transmission advantages of extremely fine coaxial fiber bundles in AI devices

With the rapid development of artificial intelligence technology, the data transmission rate inside AI devices continues to rise, and the requirements for signal integrity and anti-interference ability are also increasing. From autonomous driving to edge computing, from machine vision to high-performance computing platforms, various devices rely on high-speed and stable signal chains. However, traditional cables often face performance bottlenecks in high-speed scenarios. In comparison, ultra-thin coaxial cables (micro coaxial cable) demonstrate an irreplaceable advantage in AI devices with their high bandwidth, small size, and excellent electrical performance.

The key challenges of high-speed signal transmission

In AI devices, the stability of the signal chain directly affects the overall computational performance and reliability of the system. However, as the transmission rate enters the high-speed and even ultra-high-speed range, engineers need to overcome a series of challenges:

1.1 Signal waveforms are prone to distortion, and high-speed signals are extremely sensitive to the electrical uniformity of cables.

1.2 Any impedance mismatch will cause reflection, leading to a decrease in link transmission quality.

1.3 Electromagnetic interference and crosstalk are more prominent in high-density electronic systems, affecting data integrity.

1.4 AI devices are tending to become smaller, and traditional wiring harnesses are too large, which is not conducive to layout.

Temperature, humidity, and environmental factors such as mechanical bending will also affect signal stability.

These issues collectively constitute the challenges of high-speed transmission design.
