NVIDIA Active Copper Cable IB Twin Port NDR 400Gb/s OSFP 3m

Active copper cable engineered for InfiniBand NDR environments, delivering 400 Gb/s per port across twin OSFP connectors with ultra-low latency. The NVIDIA 980-9I602-00N005 leverages active signal conditioning to maintain signal integrity over 3 meters, making it a dependable link for bandwidth-intensive clusters.

Advantages

This twin-port cable doubles throughput in a single assembly, reducing cabling complexity in dense racks. Active copper construction achieves lower power draw than optical alternatives—under 2.5W per end—while preserving the low-latency characteristics essential for HPC and AI workloads. Hot-pluggable OSFP interfaces simplify deployment and maintenance.

Suitable for

• High-performance computing (HPC) clusters
• AI and machine learning training fabrics
• Cloud data centers and hyperscale infrastructure
• InfiniBand NDR switch-to-HCA connections

Key specifications

• Data rate: 400 Gb/s per port (NDR)
• Connector: OSFP twin-port
• Length: 3 meters
