Industrial Vision High-speed Transmission Solution Analysis: Ultra-thin Coaxial Cable Application

In industrial vision systems, the camera module is the core link for image acquisition and analysis. With the continuous improvement of resolution, frame rate, and data volume, the module's data transmission interface is evolving from low-speed to high-speed. Currently, common interfaces include USB3.0, GigE, Camera Link, CoaXPress, MIPI CSI, LVDS, SLVS-EC, HDMI, DisplayPort, and PCIe, each with its own characteristics in terms of bandwidth, transmission distance, anti-interference ability, and cable matching methods. Choosing the appropriate interface and cable assembly is crucial for ensuring the stable operation of industrial vision systems.

Part 1: Performance Characteristics of Mainstream High-Speed Interfaces

USB3.0 bandwidth can reach 5Gbps, with low cost and good compatibility, suitable for mid-range industrial cameras; GigE transmission distance can reach 100 meters, suitable for multi-camera distributed systems; Camera Link interface is stable but cables are relatively thick; CoaXPress has high bandwidth and can be transmitted over long distances, making it the mainstream of high-end vision systems; MIPI CSI is used for embedded and AI vision modules, with high speed but high requirements for signal integrity; LVDS/SLVS-EC is suitable for short-distance high-speed transmission; HDMI/DisplayPort is mainly used for display transmission, adopted by some customized cameras; PCIe direct connection to CPU/GPU, with low latency, suitable for AI and high-performance computing scenarios. With the increase in data rates, traditional wiring and copper cable bundles are difficult to meet the requirements for high-speed transmission.

Advantages of ultra-fine coaxial beam

The extremely thin coaxial cable assembly is composed of independent shielded miniature coaxial units, with each core wire having an independent shielding layer, effectively reducing crosstalk and EMI interference. It supports transmission above 20GHz and is compatible with high-speed interfaces such as USB4, MIPI, and CoaXPress; with a diameter of 0.3~0.8mm, it allows flexible cabling in compact spaces; the precise impedance control ensures that high-speed data is not distorted; the shielding structure is reliable with strong anti-interference ability, and performs outstandingly in industrial environments. Therefore, the extremely thin coaxial cable assembly is gradually replacing traditional multi-core cable assemblies and becoming the preferred transmission solution for AI vision modules, industrial CCDs, automatic inspection cameras, and medical imaging equipment.

Section 3: Application Trends of Interface and Harness Matching

The current high-speed interfaces such as MIPI, CoaXPress, and PCIe have extremely high requirements for signal integrity, which traditional cables are difficult to meet. Micro Coax, while ensuring the stability of high-speed signals, also meets the needs of module miniaturization and lightweight design. It has become a standard configuration in AI cameras and industrial automation detection systems. With the upgrade of high-speed interface standards, the application ratio of ultra-thin coaxial cables in industrial vision systems will continue to rise. Their high signal integrity, anti-interference capability, and wiring flexibility make them an important supporting technology for high-speed transmission.
