BlueOptics NVIDIA 980-9IA3T-00W002 BlueLAN Passive 400GBASE-CR8 QSFP-DD to 2x200GBASE-CR4 QSFP56 Direct Attach Breakout Cable, 2m

The BlueOptics NVIDIA 980-9IA3T-00W002 BlueLAN passive 400GBASE-CR8 QSFP-DD to 2x200GBASE-CR4 QSFP56 Direct Attach Breakout Cable is a high-performance, cost-effective solution for data center and high-performance computing (HPC) environments. This breakout cable enables seamless connectivity from a single 400G QSFP-DD port to two 200G QSFP56 ports, supporting aggregate data rates of 400 Gbps. Designed for passive copper operation, it ensures low latency and zero power consumption, making it an ideal choice for short-reach interconnects.

Advantages

This cable offers significant advantages in network flexibility and density. By breaking out a 400G link into two 200G links, it allows for efficient utilization of existing infrastructure and simplifies network upgrades. The passive design eliminates the need for external power, reducing overall system power consumption and heat generation. Additionally, the direct attach construction provides a reliable, low-cost alternative to active optical cables for distances up to 2 meters.
