Preferred high-speed interconnect for AI servers: Ultra-fine coaxial cable bundle analysis

As the scale of AI training models continues to expand, the data transmission speed and signal integrity between AI servers have become the focus of the industry. Traditional ribbon cables or twisted pairs are prone to interference and loss in high-speed transmission, making it difficult to meet the requirements of high bandwidth and low latency. The extremely thin coaxial cable bundle (micro coaxial cable), with its excellent electrical performance, has gradually become an important choice for high-speed interconnection of AI servers.

I. Electrical Advantages of Extremely Fine Coaxial Beam

The extremely fine coaxial cable束 adopts a coaxial structure, with the conductor tightly enclosed by a shielding layer, which effectively reduces electromagnetic interference (EMI) and ensures signal integrity. In the high-speed interconnection of AI servers, this feature is particularly critical, whether it is the high-speed connection between GPUs or the communication between CPUs and AI accelerators, the reduction of signal loss directly affects computing efficiency and system stability.

Support high-speed transmission

With the promotion of PCIe 5.0, CXL, and higher bandwidth interconnect standards, cables need to support transmission rates exceeding 32Gbps and even higher. The low-loss characteristics of ultra-thin coaxial cables ensure stable eye diagram performance at high frequencies, reduce bit error rates, and improve overall system performance. This makes it a reliable solution for high-speed interconnects in AI servers.

Three, Flexibility in Space and Design

The internal components of an AI server are dense and space is limited. The extremely thin coaxial cable bundle has a small diameter and good bending performance, which not only saves wiring space but also enables flexible layout within the limited cabinet, providing more possibilities for heat dissipation and modular design. At the same time, its high-density support and reliable connection ensure that the requirements for multi-channel interconnection are met, further enhancing the system's scalability and performance stability.

As the demand for AI computing power continues to grow, the interconnection speed between servers is constantly increasing. The ultra-fine coaxial cable bundle, with its advantages of high speed, low loss, strong shielding, and flexible design, has become a key choice for improving the performance and stability of AI servers. With the continuous evolution of high-speed interconnect standards, its importance in the data center and high-speed interconnect field will continue to rise.
