The potential of extremely thin coaxial beam in 8K ultra-high-definition video

With the continuous development of display and imaging technology, 8K ultra-high-definition video is gradually moving from the professional field to mass applications. From medical image diagnosis, industrial inspection, to high-end display terminals and immersive entertainment experiences, 8K poses new challenges to the bandwidth, anti-interference capability, and stability of the signal transmission system. So, can the extremely thin coaxial cable (micro coaxial cable) meet the high-speed transmission requirements of 8K video signals?

I. Main Characteristics of Ultra-Fine Coaxial Beam
Extremely thin coaxial cable bundles are known for their compact structure, high flexibility, and strong anti-interference ability. They consist of a central conductor, insulating layer, shielding layer, and outer sheath, which can effectively reduce signal crosstalk and external electromagnetic interference. Due to their extremely small diameter, such cable bundles are often used in applications that require extremely high installation space, such as laptop screens, industrial cameras, and endoscope equipment. In high-frequency signal environments, their low loss characteristics make them capable of transmitting high-resolution image signals.

Part Two, Technical Challenges of 8K Signal Transmission
The resolution of 8K video can reach 7680×4320, with extremely high data transmission rate, which puts extremely strict requirements on bandwidth, impedance matching, and signal integrity. Taking the HDMI 2.1 standard as an example, its maximum bandwidth can reach 48Gbps, which means any slight impedance mismatch or inadequate shielding can cause signal attenuation or distortion. Particularly in long-distance transmission, ordinary cables are difficult to ensure stable output, and it is extremely easy to experience issues such as image flickering, delay, or noise interference.

Three, the applicability of ultra-fine coaxial cables in 8K applications
In short-distance connections within the device, extremely fine coaxial cable bundles have the capability to support the high-speed transmission of 8K video signals. By reasonably selecting the cable diameter, improving the shielding layer structure, and using insulating materials with low dielectric constants, high-speed and low-loss transmission can be achieved within a limited space. For example, in internal connections from camera modules to processing mainboards, and in signal conduction within medical monitoring equipment, extremely fine coaxial cables can meet both high bandwidth and lightweighting requirements. However, if the transmission distance is longer or the electromagnetic interference is severe, signal equalization, amplifiers, or optoelectronic conversion techniques must be used in conjunction to ensure signal quality and image stability.

The extremely thin coaxial cable束 indeed has the potential to transmit 8K video signals, especially performing excellently in the field of short-distance high-speed interconnection. However, in long-distance or complex working conditions, relying solely on a single cable solution is still difficult to meet all performance requirements. Choosing the appropriate cable structure and matching technology is the key to perfect presentation of 8K ultra-high-definition video.
