With the continuous popularization of 4K/8K ultra-high-definition video technology, the data transmission rate within the video module continues to rise. In order to maintain clear image quality and stable performance in a high-speed signal environment, the choice of cable is particularly crucial. Micro coaxial cable (Micro Coaxial Cable) boasts advantages such as small size, high bandwidth, and strong anti-interference ability, making it an ideal choice for high-speed signal transmission within video modules.
The technical advantages of ultra-fine coaxial beam
1.1 Outstanding high-speed transmission capability
In 4K/8K video modules, the signal rate often reaches several GHz, even exceeding 12GHz, and ordinary cables are difficult to meet the requirements. Extremely thin coaxial cables can stably support the data transmission of high-speed interfaces such as LVDS, FPD-Link, and MIPI, providing reliable bandwidth guarantee for high-definition video signals.
1.2 Precision Impedance and Low Crosstalk Performance
High-speed signals have extremely high requirements for impedance consistency. Extremely thin coaxial cable bundles are usually designed as 50Ω or 100Ω precise impedance structures, which can effectively reduce crosstalk and signal reflection, ensuring the integrity and stability of high-speed signals in complex electromagnetic environments.
1.3 Compact in size and excellent in flexibility
The diameter of ultra-fine coaxial cables is generally only 0.3~0.5mm, allowing flexible wiring in narrow spaces such as board-to-board and module interiors. Their excellent bending performance enables engineers to achieve high-density connections in compact layouts, balancing design freedom and signal quality.
Typical application scenarios
2.1 Industrial and scientific camera module
In high-resolution industrial cameras or scientific imaging equipment, extremely fine coaxial cables are used for high-speed data transmission between the image sensor and the signal processing chip, ensuring the clarity and stability of image acquisition.
2.2 Medical Imaging Equipment
In endoscopes, ultrasonic probes, and other precision medical equipment, extremely thin coaxial cables bear the task of transmitting high-definition image signals, helping medical imaging systems achieve high-resolution diagnosis.
2.3 Drones and Smart Terminals
In drone camera modules, smart wearable devices, and other products, miniature coaxial cables can transmit high-speed video and sensor signals within limited spaces, while also reducing system weight and improving device reliability.
2.4 High-end Display Module
LCD, OLED and other high-end display module internal LVDS, eDP signal transmission also widely uses extremely thin coaxial cables to ensure signal consistency and stability during high-resolution image output.
The future development trend
With the continuous increase in resolution, refresh rate, and the demand for real-time data transmission, ultra-thin coaxial cable束 is evolving towards higher bandwidth, smaller diameter, and lower crosstalk. Particularly in emerging fields such as AI, AR/VR, and vehicle vision, the demand for high-speed, flexible, and lightweight cables is becoming increasingly urgent. The technological upgrade of ultra-thin coaxial cable束 will become an important force driving the continuous development of high-performance video and image systems.
Extremely fine coaxial cable束, with its small size, high bandwidth, low crosstalk, and excellent flexibility, has become an irreplaceable key component in the high-speed signal transmission of 4K/8K video modules. It not only ensures signal integrity and system stability, but also brings more flexibility and reliability to the structural design of complex electronic modules.
