Description

Technical Field

[0001] The present invention relates to the technical field of cable connection, in particular to a multi-channel cable connector. Background Art

[0002] With the rapid development of mobile communications and AI, the demand for data centers and computing centers has exploded. The application background of 224Gbps high-speed copper cables mainly stems from the growing demand for high-performance computing in data centers, especially the continuous improvement of computing power and communication speed in AI model training. ‌With the increasing complexity and scale of AI models, the demand for computing power is also increasing, which has prompted data centers to require higher transmission rates and lower energy consumption to achieve efficient data processing and transmission. The emergence of 224G high-speed copper cable technology just meets this demand. With its significant advantages such as low energy consumption, high transmission rate and low deployment and maintenance costs, it has become an ideal interconnection solution for AI large model data centers. In addition, as data centers develop towards a cluster scale of tens of millions, the demand for high-speed copper cables is also continuing to grow. Ethernet has become the core technology to promote the expansion of computing clusters due to its affordable price. It is the key to achieving high-bandwidth communication between GPUs, which helps to break through the performance limitations of a single chip and is one of the key directions for the development of future data center network architecture.
