CXP High-Speed Transmission Era: Why Choose Ultra-Fine Coaxial Cable Assemblies

With the continuous development of machine vision, automated detection, and medical image systems towards higher resolution and frame rates, the image acquisition chain requires faster, more stable, and lower noise transmission. As one of the mainstream high-speed image interfaces, CoaXPress (CXP) is widely used due to its advantages of high bandwidth, strong anti-interference, and long-distance transmission. Under the background of continuous miniaturization of equipment and increasingly compact structural space, ultra-thin coaxial cables (micro coaxial cable) are becoming the key interconnection method in CXP systems due to their lightweight, flexibility, and excellent signal characteristics.
This article will focus on the CXP feature, analyzing the value and engineering application points of ultra-fine coaxial cable束 in high-speed image transmission.

I. High-speed transmission characteristics of CXP interface

CoaXPress is a coaxial transmission standard for high-speed industrial cameras, with core features including high bandwidth (up to 12.5 Gbps per channel), simultaneous video, control, and power (PoC) channels, as well as long-distance transmission and excellent anti-interference performance. As camera sizes shrink and interface integration improves, traditional thicker coaxial cables are limited in terms of wiring flexibility, bend radius, and weight, which promotes the application of finer and more flexible micro coaxial cable bundles in CXP's high-speed interconnects.

The structural characteristics and advantages of ultra-fine coaxial beam束

Fine coaxial cable bundles are usually composed of miniature coaxial cables with a 36~42 AWG gauge, featuring precise characteristic impedance control, a full shielding layer structure, and excellent flexibility. Thanks to these characteristics, it can effectively ensure the integrity of high-speed signals, reduce insertion loss, reflections, and EMI interference, and also meet the complex wiring needs in compact spaces. Multiple cables can be integrated into flat or round bundle structures, further enhancing the wiring density and system lightweight performance.

The application value and engineering points in the CXP system

In high-speed transmission scenarios, extremely thin coaxial cable bundles can significantly enhance the flexibility of system design, reduce wiring space occupation, and are particularly suitable for motion parts such as industrial cameras, robot joints, and sliding track mechanisms. In practical engineering, attention should be paid to issues such as impedance consistency, the impact of bending on insertion loss, suppression of crosstalk between multi-bundles, current and temperature rise management under PoC power supply, and the matching of cable length and signal rate, in order to ensure the long-term stable operation of the high-speed link.

Extremely thin coaxial cable bundles, with their high density, precise impedance, high shielding, and flexible characteristics, are becoming an indispensable interconnection solution in CoaXPress high-speed image transmission systems. They not only meet the stringent requirements for signal integrity of high-speed links but also take into account lightweight and flexible cabling, allowing the system to maintain stable performance in compact spaces and moving structures. As the CXP interface speed continues to increase, extremely thin coaxial cable bundles will play an even more critical role in fields such as machine vision, automatic detection, and medical imaging.
