Extremely thin coaxial cable束: The ideal choice for high-speed signal transmission of USB3.x

Today, with the increasing popularity of high-speed data transmission, USB3.x interfaces (including USB 3.0, 3.1, 3.2, and so on) have become the standard configuration for computer, camera, industrial equipment, and other systems. However, protocol design alone cannot fully ensure the stable transmission of high-speed signals; the cable structure is also crucial. Compared with traditional FFC ribbon cables or ordinary twisted pairs, the extremely thin coaxial cable (Micro Coaxial Cable) is gaining popularity as the preferred solution for USB3.x high-speed transmission due to its excellent performance.

Excellent signal integrity

The transmission rate of USB3.x can reach 5~20Gbps, and any slight impedance mismatch, reflection, or crosstalk can cause signal distortion or error. The symmetrical structure of the shielding layer, central conductor, and insulating layer in the extremely thin coaxial cable bundle forms a stable characteristic impedance channel, making the signal transmission path controllable, with minimal reflection and clean waveforms. It can maintain clear eye diagrams and data integrity of USB3.x differential signals under high-speed transmission.

Electromagnetic Compatibility and Advantages of Flexible Wiring

The shielding structure of ultra-fine coaxial cable束 effectively blocks electromagnetic coupling, reduces signal leakage and external interference, and improves the device's resistance to EMI/EMC. This is particularly important in electronic intensive spaces such as laptops, camera modules, and drones. At the same time, its small diameter and high flexibility make wiring more flexible, allowing it to easily pass through narrow spaces or hinge structures, maintaining stable performance even after frequent bending, and adapting to the compact design requirements of modern equipment.

III. Adapt to high-speed transmission trends and high reliability

With the popularity of high-speed interfaces such as USB3.x, MIPI, DisplayPort, and Thunderbolt, the demand for low-loss, high-shielding, and flexible transmission media is increasingly rising. Extremely thin coaxial cable bundles meet these conditions, while the manufacturing process is mature, customizable designs ensure impedance consistency and shielding performance. Whether it is consumer electronics or industrial equipment, it demonstrates high reliability and mass production consistency, gradually replacing traditional cables and becoming the mainstream solution for high-speed transmission.
