Miniature ultra-fine coaxial cable: the invisible core for high-speed transmission in augmented reality glasses

In the design of augmented reality (AR) glasses, the speed and stability of data transmission determine the ultimate user experience. With the continuous improvement of AR display resolution, traditional signal transmission solutions are difficult to meet the dual requirements of high bandwidth and low latency. At this point, micro ultra-fine coaxial cables, with their excellent electrical performance and flexible structure, have become a key transmission solution for AR devices.

Structure advantage: precision and efficiency coexist
Very fine coaxial cables usually use ultra-fine conductors (common specifications are AWG 40-46), with an overall outer diameter of only about 2 millimeters. They are composed of a central conductor, an insulating layer, and a shielding layer, featuring low insertion loss, stable impedance, and strong anti-interference characteristics.
This precise structure ensures that the signal is almost undistorted during high-speed transmission, and it can maintain excellent signal integrity even in a high-density electronic module environment.
The application value of AR glasses
High bandwidth transmission capability
AR glasses need to process multiple high-resolution video and image signals simultaneously. Extremely thin coaxial cables have high-frequency transmission characteristics, which can meet the bandwidth requirements for 4K and even higher resolution displays, ensuring smooth images and accurate colors.
Low-latency real-time response
In AR interactive scenarios, the lower the latency, the stronger the immersion. Micro Coaxial Cable, with its high conductivity and low reflection characteristics, achieves extremely small signal latency, facilitating the immediate synchronization of vision and motion.
Flexible wiring and lightweight design
AR glasses have limited space, which imposes strict requirements on the flexibility and size of the cables. The extremely thin coaxial cable has a small diameter and a small bending radius, allowing for free routing in narrow spaces, which contributes to the lightweight and compact design of the equipment.
Excellent anti-interference performance
AR systems integrate various sensors and communication modules, which are highly susceptible to electromagnetic noise interference. The extremely fine coaxial cables with multi-layer shielding structures can effectively isolate external interference, ensuring stable and reliable image and data transmission.

III. Future Prospects: Key Interconnection Solutions for the AR Ecosystem
With the rapid evolution of AR technology and the diversification of terminal devices, Micro Coaxial Cable will continue to play a core role in high-resolution, low-power consumption, and high-speed transmission. It is not only the ideal transmission medium for current AR glasses but will also support the performance breakthrough of the next generation of immersive devices.

The extremely fine coaxial cable, with its advantages of high bandwidth, low latency, strong anti-interference and flexible wiring, is becoming an indispensable key component in the design of AR glasses. As the technology in the industry continues to upgrade, its value in the AR and related wearable device fields will become increasingly prominent.
