Application advantages of extremely fine coaxial cable束 in audio and video systems

In the design of audio and video systems, signal integrity has always been a core issue. With the development of high-definition displays, AR/VR headsets, and in-car entertainment systems, engineers are facing the challenge of how to ensure stable transmission of high-resolution video and high-fidelity audio within limited spaces. In recent years, extremely fine coaxial cable harnesses (Micro Coaxial Cable Harness) have gradually replaced traditional wiring due to their excellent electrical performance and mechanical flexibility, becoming the mainstream interconnection scheme in audio and video systems.


 

Bandwidth and High-Speed Characteristics

Modern audio and video applications increasingly demand higher data transmission rates. Extremely fine coaxial cable bundles ensure consistent characteristic impedance through the coaxial structure, supporting high-speed interfaces such as eDP, MIPI, and HDMI, achieving stable transmission of 4K/8K video and high-bitrate audio. Compared with traditional FPC or ribbon cables, it has a significant advantage in maintaining high-speed signal edges, insertion loss control, and signal integrity, meeting the bandwidth requirements for high-resolution video and high-fidelity audio.


 

Two, EMI and Crosstalk Control

In complex electromagnetic environments, audio and video signals are prone to interference, leading to degraded picture quality or audio distortion. The extremely thin coaxial cable bundle has a complete shielding layer in its structure, combined with reasonable weave density and termination technology, which can effectively suppress EMI/RFI interference and reduce crosstalk between lines. This high-efficiency electromagnetic protection capability is particularly crucial for in-car central control screens, medical imaging equipment, and other scenarios with extremely high requirements for signal stability, ensuring reliable operation of the system under high interference environments.


 

Three, space adaptation and system-level experience optimization

With the development of equipment slimming, the wiring space is becoming more and more limited. The diameter of extremely thin coaxial cable bundles is usually between 0.3~0.5mm, with good flexibility, suitable for narrow bending environments, such as laptop hinges, folding screen hinges, etc. Compared with traditional cables, they have higher mechanical adaptability, and while ensuring signal performance, they also consider the flexibility of the whole machine design. In system-level applications, extremely thin coaxial cables can maintain a more complete transmission characteristic from the source to the display end, reducing signal retransmission and error codes, and improving the overall stability of the whole machine. This means that users can obtain clearer images, cleaner audio, and lower latency, enhancing the overall user experience.


Extremely thin coaxial cable bundles not only undertake the function of signal transmission in audio and video systems, but also provide a solution that balances performance and manufacturability in high-speed, high-interference, and small space environments. It achieves improved signal integrity and system reliability through stable characteristic impedance, effective shielding, excellent flexibility, and high bandwidth support. With the continuous increase in audio and video resolution and transmission speed, micro coax will continue to play a significant role in more high-performance application scenarios.
