I-PEX 82892-100B-02-D 50P high-speed signal transmission ultra-fine coaxial cable replacement

Why does USB 3.2 require extremely thin coaxial cable bundles in the era of high-speed transmission?

With the development of laptop computers, AI terminal devices, industrial vision devices, intelligent display devices, and high-speed data collection equipment, high-speed interfaces such as USB 3.2 have put forward higher requirements for internal wiring harnesses. Compared with traditional low-speed signal transmission, high-speed USB 3.2 Gen2 data transmission not only requires higher data bandwidth but also imposes strict requirements on signal integrity, impedance control, electromagnetic compatibility (EMI), and spatial layout capabilities. In the design of wiring harnesses related to USB Type-C/USB 3.2, it is necessary to focus on controlling differential signal loss, impedance matching, and crosstalk issues to ensure stable high-speed data transmission. USB-IF

Traditional multi-core ribbon cables, although cost-effective, are prone to be affected by the following factors in high-speed signal environments:

As the transmission frequency increases, the edge speed of the signal becomes faster and faster, making it easy for crosstalk to occur between ordinary parallel wires, and the external electromagnetic environment may also affect the signal quality. In addition, within ultra-thin devices, the space for connections continues to shrink, and traditional wire bundles are difficult to meet the comprehensive demands of "miniaturization, high-speed, and high reliability" simultaneously.

The ultra-fine coaxial cable (Micro-Coaxial Cable) adopts an independent shielding structure, with each signal line having good electromagnetic isolation capability. This effectively reduces interference between signals and improves the stability of high-speed differential signal transmission, thus gradually becoming an important solution for internal connections in USB 3.2, high-speed display, high-speed camera, and AI devices.

For engineers, choosing extremely thin coaxial cables is not only to meet the requirements of high-speed transmission, but also to address issues such as signal integrity, EMI control, and spatial layout in the early stage of product design.
