How to achieve 4K image transmission with a 0.18 mm ultra-fine coaxial cable

With the popularity of 4K ultra-high-definition images in laptops, medical equipment, drones, and industrial cameras, the performance of image transmission cables has become particularly crucial. The requirements of devices for high bandwidth, high signal integrity, and lightweight make micro coaxial cables an ideal choice. Many people may wonder: Can an extremely thin coaxial cable with an outer diameter of only 0.18 mm really handle 4K image transmission? This article will analyze in detail from five aspects: structure, bandwidth, flexibility, interface design, and application cases.

Extremely thin wire diameter but complete structure

Despite its extremely thin wire diameter, the micro coax still retains the complete coaxial structure, including the central conductor, insulating medium, metallic shielding layer, and outer sheath. The precise manufacturing process ensures stable characteristic impedance, effectively reducing the reflection and distortion of high-frequency signals, allowing the extremely thin cable to maintain good signal integrity in high-speed data transmission.

High frequency bandwidth supports 4K transmission

4K video transmission usually requires bandwidths of several GHz. 48 AWG micro coax utilizes low-loss media and high-density shielding design, which can maintain signal integrity within limited lengths. It meets the transmission requirements of high-speed interfaces such as MIPI, eDP, and LVDS. In scenarios with longer distances or higher bandwidth demands, overall transmission capability can be enhanced by multi-core parallel wiring to ensure stable and distortion-free image signals.

Lightweight and flexible, adaptable to compact spaces

The 0.18 mm micro coax is not only lightweight but also highly flexible. It can be bent and routed multiple times in confined spaces, making it very suitable for compact systems such as drones, endoscopes, wearable devices, and high-resolution notebook screen modules. The lightweight design also reduces equipment burden and saves cabling space, facilitating high-speed image transmission.

Four, the design of connectors is also crucial.

High-quality cables also require matching connectors to fully utilize their performance. Micro coaxial cables are typically used with ultra-fine pitch high-frequency interfaces to ensure the continuity of impedance at the connection point and the integrity of shielding. If the interface design is not reasonable, even if the cable itself has high-speed transmission capabilities, it may cause signal reflection or attenuation, affecting the transmission effect of 4K images. Therefore, the cable and interface design must be optimized together.

Five, Application Cases

In high-resolution camera modules, multi-core micro coaxial cables are widely used to connect image sensors with processing boards at high speed. Each cable is responsible for transmitting differential signal channels, and precise shielding can effectively reduce interference, thus stabilizing the output of images with 4K resolution and even higher. This fully demonstrates the important role of ultra-fine coaxial cables in compact high-end visual systems.



0.18 mm micro coax can achieve 4K image transmission due to its precise coaxial structure, stable impedance control, efficient shielding design, and matching connector scheme. It achieves a balance between lightweight and high bandwidth, providing a reliable guarantee for high-speed image transmission in miniaturized equipment. With the continuous improvement of image device resolution, micro coax will play an even more critical role in high-end visual systems.
