Mellanox / NVIDIA MCP1660-W01AE30 400G QSFP-DD DAC Passive Copper Cable 1m

The Mellanox MCP1660-W01AE30 is a 400G QSFP-DD passive direct-attach copper (DAC) cable engineered for ultra-short-reach, high-bandwidth interconnects in enterprise data center environments. Designed specifically for NVIDIA Quantum-2 InfiniBand switches and BlueField-3 DPU deployments, this cable delivers full 400 Gbps throughput over a 1-meter span with zero active components, eliminating latency and power overhead inherent to active solutions.

The passive copper construction provides superior signal integrity and reliability for rack-scale and pod-scale fabric deployments where cable runs remain within 1-3 meters. The QSFP-DD form factor supports 8 parallel 50 Gbps lanes, enabling adoption in next-generation high-performance computing (HPC), AI/ML training clusters, and large-scale data analytics workloads that demand deterministic, low-latency communication.

Launched in Q1 2022, this cable has become a critical infrastructure component for organizations deploying NVIDIA's latest accelerated computing platforms. The MCP1660-W01AE30 integrates seamlessly into existing Quantum-2 fabric architectures and is qualified for production deployments in mission-critical environments requiring carrier-grade reliability.

Ideal for

• NVIDIA Quantum-2 InfiniBand fabric construction for hyperscaler AI/ML training clusters
• BlueField-3 DPU-to-switch interconnects in cloud infrastructure deployments
• High-performance computing (HPC) node-to-switch cabling in supercomputing facilities
• Low-latency storage area network (SAN) interconnects for all-flash arrays
• Rack-scale GPU cluster interconnects for real-time analytics and inference serving
• Financial services tick-to-trade infrastructure requiring sub-microsecond latency
