Miniature ultra-fine coaxial cable: The invisible core for high-speed transmission in AR glasses

In the design of augmented reality (AR) glasses, the speed and stability of data transmission determine the ultimate user experience. With the continuous increase in AR display resolution, traditional signal transmission solutions are no longer able to meet the dual requirements of high bandwidth and low latency. At this point, micro ultra-thin coaxial cables, with their excellent electrical performance and flexible structure, have become a key transmission solution for AR devices.

One, structural advantage: precision and efficiency coexist.
Extremely thin coaxial cables usually use ultra-fine conductors (common specifications are AWG 40-46), with an overall outer diameter of only about 2 millimeters. They consist of a central conductor, insulation layer, and shielding layer, and possess 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 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. The extremely fine coaxial cables have high-frequency transmission characteristics, which can meet the bandwidth requirements for 4K resolution and even higher, ensuring smooth image quality and accurate color.
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 low signal delay, helping to synchronize vision and motion in real time.
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 cables have a small diameter and small bending radius, allowing for free routing in narrow spaces, contributing to the lightweight and compact design of the device.
Excellent anti-interference performance
AR systems internally 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.

Section 3: 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 ultra-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 industry technology continues to upgrade, its value in the AR and related wearable device fields will become more and more prominent.
