Why Choose This Product?

• 400G-to-2×200G breakout – Allows one 400Gb/s source connection to serve two 200Gb/s links, improving port utilization.
• HDR InfiniBand ready – Designed for high-performance InfiniBand environments where bandwidth and efficient data movement are critical.
• Active optical construction – Provides optical connectivity for the specified 3m breakout application without requiring separate transceiver modules at each cable end.
• 3m reach – Gives data-center architects more flexibility when switch and server positions require additional cable distance.
• AI/HPC focused – Well suited to GPU clusters, supercomputing and other bandwidth-intensive infrastructure.
• High-density connectivity – Helps simplify 400G-to-200G fabric designs while supporting dense rack architectures.
• NVIDIA Mellanox ecosystem – Provides a purpose-designed cable option for compatible NVIDIA/Mellanox InfiniBand infrastructure.
• Deployment flexibility – Particularly useful where 400Gb/s HDR switch ports need to connect to multiple 200Gb/s endpoints.
