How to transmit the data of 8K industrial cameras? Analysis of high-speed cable scheme

In industrial vision systems, as the detection accuracy continues to improve, 8K industrial cameras have become the core configuration of more and more high-end equipment. However, what 8K brings is not only higher resolution; the data volume that comes with it also grows exponentially, posing higher requirements for signal transmission methods, cable structures, and connector performance. Many people are puzzled when selecting or debugging equipment: What kind of cable does an 8K camera rely on to stably transmit such a large amount of data?

8K visual system commonly used high-speed transmission methods

In 8K industrial cameras, the common high-speed interfaces mainly include CoaXPress 2.0 and Camera Link HS. CoaXPress, with its single channel bandwidth reaching tens of Gbps, has become the mainstream solution and can further expand the throughput through multi-channel parallelism. These interfaces address the high-speed transmission capabilities at the protocol level, but it is still the physical layer's cable structure that truly undertakes the data transmission task. Therefore, to ensure stable output of 8K data, it is necessary to choose high-performance transmission cables that match the high-speed protocols.

Why does the 8K system commonly use micro coaxial cable (micro coaxial cable)?

Among the many types of cable, the micro coaxial cable has almost become the standard for 8K industrial cameras, mainly due to the following reasons:

1. Strong shielding performance: The 8K signal is fast and sensitive, and the extremely fine coaxial structure has excellent shielding capability, which can effectively reduce interference, packet loss, and error rates.

Small volume and flexible layout: The internal space of industrial cameras is compact, and multi-channel wiring must be as miniaturized as possible. Micro coaxial cables just meet the demand for high-density interconnection.

3. High flexibility and bend resistance: In dynamic applications such as AOI, 3D detection, and robotic arms, cables need to follow motion for a long time. The flexibility of extremely fine coaxial cables makes them more reliable.

In long-distance transmission scenarios, some devices also choose active fiber optic cables to achieve long-distance data transmission of 8K.

Connector matching is another core key to high-speed transmission

High-quality harnesses are inseparable from high-speed connectors of the same grade. High-speed interfaces from manufacturers such as I-PEX, Hirose, and JAE are commonly used for micro coaxial cable harness termination, including impedance control, terminal accuracy, and insertion/extraction life, all of which are directly related to image stability. In the actual application of certain 8K devices, engineers often strictly require the consistency of harness impedance, and remind that during assembly and maintenance, the harness should not be bent arbitrarily—as even minor damage can cause high-speed signal jitter or abnormal images.

The 8K industrial vision system can stably output high-bandwidth images due to the combined effects of high-speed interface protocols, high-performance cables, and high-speed connectors. Micro coaxial cable has become a mainstream choice because it has comprehensive advantages in high-speed transmission, anti-interference, miniaturization, and flexibility, and is one of the most mature and reliable high-speed interconnection solutions for current compact industrial vision equipment.
