The Era of High-Speed Signals: Why Is It Not Just "Good Enough" for Ultra-Fine Coaxial Bundles?

In the past, in electronic design, simply being conductive was the measure of harness quality. However, in the era of high-speed signal transmission, especially when using extremely thin coaxial cables (Micro Coaxial Cable), mere conductivity is far from enough. In applications such as AI platforms, Jetson Orin, drones, and vehicle systems, where signal rates reach several Gbps or even tens of Gbps, the harness not only needs to conduct electricity but also ensure signal integrity, low loss, and anti-interference capability to support the high-performance operation of modern electronic systems.

A: Fine coaxial beam transmission and quality

The extremely fine coaxial cable束 consists of a central conductor, insulating layer, shielding layer, and outer sheath, and is widely used for internal high-speed signal transmission in applications such as high-speed camera modules, AI platforms, drones, and vehicle-mounted systems. In these scenarios, signal performance not only depends on conductivity, but is also affected by impedance matching, insertion loss and return loss, crosstalk and EMI, as well as delay and phase error factors. The traditional concept of "good enough conductivity" is not sufficient to meet the requirements for stable transmission of high-speed signals.

High-speed signal turns conduction into conduction quality

In high-speed signal links, cables are no longer just conductors but transmission media, with signal propagation more like the coupling of electromagnetic waves between conductors and media. Any impedance mismatch, shielding defect, or processing error can cause reflections, interference, or communication errors. Therefore, determining whether a cable harness is qualified is not about whether it can be powered on, but about whether the signal can pass through stably, completely, and at high speed, ensuring the reliability of high-speed data transmission.

Three, the design误区of just making it conductive

If still using the thinking of high-speed harness design, it may lead to poor signal integrity, high system error rate, insufficient reliability, and difficult debugging. The problem is often not a broken wire, but signal attenuation or phase drift, which is difficult to identify with the naked eye. Modern high-speed systems require harnesses to have stability, low loss, anti-interference, and high consistency on the basis of ensuring conductivity to truly support high-performance applications.

In the era of high-speed signals, simply being conductive is outdated. Extremely thin coaxial cable assemblies, through precise impedance control, excellent shielding, strict processing, and high-speed testing verification, ensure signal integrity, low loss, and anti-interference capability, which are the core components for modern electronic systems to achieve high-quality data transmission. True high-speed connections are not just about being able to conduct electricity, but about being able to transmit signals of high quality, which directly determines the reliability, performance, and competitiveness of the equipment.
