The 400G QSFP-DD to 2 x 200G QSFP56 Passive Direct Attach Copper Breakout Cable is engineered to provide a reliable, cost-effective solution for high-speed data center interconnections. This cable is designed to convert a single 400G QSFP-DD port into two separate 200G QSFP56 ports, enabling flexible network configurations without the need for additional active components. Its passive direct attach copper design ensures low latency and minimal power consumption, which are critical factors in high-density environments where efficiency and performance are paramount.
Constructed with high-quality materials, the cable offers robust electrical performance over short-reach distances, typically up to 3 meters. The passive design eliminates the need for signal conditioning or amplification, thereby reducing complexity and the potential for failure. This approach not only enhances reliability but also simplifies the deployment process, making it an ideal choice for server-to-switch or switch-to-switch connectivity within modern data centers.
The breakout cable adheres to industry standards, ensuring compatibility with a wide range of networking equipment. The QSFP-DD connector on one end interfaces seamlessly with high-speed transceivers, while the dual QSFP56 connectors on the other end provide flexible connectivity options for devices requiring lower aggregate speeds. This configuration is particularly useful in scenarios where data from a single high-bandwidth source needs to be distributed across multiple lower-speed links, thereby optimizing resource utilization and network performance.
Designed with precision engineering, the cable minimizes signal loss and electromagnetic interference, ensuring stable and consistent data transmission. Its copper construction provides inherent durability and mechanical stability, making it suitable for the rigorous demands of data center operations. In addition, the cable’s simple, passive architecture contributes to lower overall system costs by reducing both power requirements and the need for active circuitry.
Overall, the 400G QSFP-DD to 2 x 200G QSFP56 Passive Direct Attach Copper Breakout Cable is a practical solution tailored for the evolving needs of modern network infrastructures. By bridging the gap between high-density 400G interfaces and more manageable 200G connections, it offers network operators an efficient method to scale and adapt their data center architectures while ensuring high performance, reliability, and ease of installation.
