Selection Secrets for High-Frequency and High-Speed Equipment Cables: Why Extremely Fine Coaxial Cables Are Absolutely Necessary

In the context of modern electronic devices increasingly pursuing miniaturization and high precision, the harness, as an important component that connects various internal components of the device, directly affects the stability and service life of the whole machine with its performance and selection. Although the ultra-fine coaxial harness and the ordinary harness have little difference in appearance, there are significant differences in structure, performance, and application scenarios. If the selection is incorrect, it may not only lead to rework, but also, in severe cases, cause equipment failure, signal interference, and even data loss. Below, we will analyze the differences between the two in detail, so that you can choose harnesses without confusion.

What is a ultra-fine coaxial cable bundle?
The ultra-fine coaxial cable assembly (Micro Coaxial Cable Assembly) consists of multiple micro coaxial cables, with diameters generally ranging from 0.2mm to 1.2mm. Its internal structure includes:
Conductor
Insulation layer
• 屏蔽层
Outer sheath
The advantage of coaxial structures lies in their strong anti-interference capability, stable signal transmission, and are particularly suitable for high-frequency, high-speed, small space, and high-density wiring applications.

What is a standard wire harness?
The ordinary harness is composed of multiple single-core or multi-core wires, which form a fixed assembly of cables through binding, covering, or connectors. It is mainly used for internal connections in home appliances, vehicles, and industrial equipment, and is suitable for low-frequency signals or power transmission.

What problems may arise from selecting the wrong harness?
Signal transmission distortion
In high-frequency or high-speed data transmission scenarios, using ordinary cables can easily cause signal attenuation and distortion, affecting equipment performance.
Severe interference
The ordinary wire harness has weak anti-interference ability, and it is prone to electromagnetic interference in high-density and high-frequency environments, leading to abnormal data.
• Limited wiring space
The wire diameter of ordinary harnesses is thicker, with a larger bending radius, which is not suitable for the fine wiring requirements of miniature devices.
• Difficult to maintain later
Choosing the wrong harness can lead to loose connections and cracked solder joints, increasing maintenance and repair costs.

Four, examples of application scenarios
Medical endoscope: Extremely thin coaxial bundles ensure high-definition image transmission at high speed, with real-time clear and interference-free surgical images.
Drone camera module: stable signal and anti-interference, ensuring uninterrupted image transmission.
High-end camera: supports 4K/8K high-definition video transmission, ensuring smooth and clear images.

The ultra-fine coaxial cable bundle and the ordinary cable bundle have obvious differences in performance, structure, and application scenarios. For high-frequency and high-speed signal transmission and miniaturized device wiring, it is necessary to use ultra-fine coaxial cable bundles. Otherwise, it not only affects the performance of the device but may also cause serious usage issues.
