InfiniBand 12X cables are high-speed data transmission cables designed for use in InfiniBand networks, supporting bandwidth-intensive applications with low latency and high throughput. The "12X" refers to 12 lanes of data, offering significantly higher data rates compared to 1X or 4X configurations. These cables are commonly used in high-performance computing (HPC), data centers, and enterprise environments. They ensure reliable, efficient connectivity between switches, servers, and storage systems.
