Who is the best choice for high-speed transmission: ultra-fine coaxial cable束 vs. ordinary cable束?

In modern electronic products, the harness is an important link for signal transmission. With the continuous development of devices towards thinness, lightness, and miniaturization, extremely thin coaxial cables (Micro Coaxial Cable) are gradually replacing traditional harnesses and becoming the preferred choice for internal connections in high-end equipment. It is changing the internal layout and signal interconnection methods of electronic products with its excellent structural design and transmission performance.

More precise structure, more compact volume
Traditional wiring harnesses are usually composed of multiple strands of wire and insulation, although simple to manufacture, they are large in size and occupy a lot of space for wiring. Extremely thin coaxial harnesses have achieved a complete signal channel structure within a limited size - with the center conductor, insulation layer, shielding layer, and outer sheath wrapped layer by layer. The wire diameter is often less than 1 millimeter, and the thinnest ones are even close to hair. This design not only ensures the integrity of the signal but also allows it to flexibly pass through narrow spaces, meeting the high-density wiring requirements of thin and light devices.

The signal transmission is more stable and has stronger anti-interference capability.
In high-speed signal environments, traditional wiring harnesses are prone to electromagnetic interference (EMI), leading to signal attenuation and distortion. The outer layer of the ultra-fine coaxial cable uses a high-density metal shielding layer, which can effectively isolate EMI. At the same time, by precisely controlling the impedance, it minimizes signal reflection. Whether it is high-definition video, camera module signals, or high-speed data transmission interfaces, it can maintain low loss and high stability, providing clear and reliable signal paths for equipment.

Flexible and versatile, easier to install
Normal wire harnesses are prone to fatigue or breakage in bending or repeated motion, while ultra-fine coaxial harnesses stand out with their excellent flexibility and bending resistance. They can be bent multiple times in confined spaces without affecting transmission performance, making them very suitable for complex and space-limited application environments such as laptop hinges, folding screen smartphones, AR/VR equipment, and drones. This high flexibility greatly enhances the freedom of device design.

Four, wider application scenarios, stronger performance potential
Traditional wiring harnesses are mostly used for low-frequency signals or power connections, while extremely thin coaxial harnesses can support signal transmission from DC to as high as 6GHz and even higher frequencies. They are particularly suitable for high-speed data and high-resolution image transmission. In fields such as consumer electronics, medical equipment, industrial testing, aerospace and aeronautics, they have demonstrated excellent performance and become an indispensable key component of high-precision electronic systems.

Compared with ordinary cables, ultra-fine coaxial cables have comprehensive advantages such as smaller volume, more stable signals, stronger anti-interference ability, and higher flexibility. They not only promote the thin and light design of electronic products but also provide reliable support for high-speed interconnection technology. In the future, with the popularity of 5G, intelligent manufacturing, and wearable devices, the application of ultra-fine coaxial cables will be more extensive.
