🌐 Overview — Purpose-Built for NDR Quantum-2 Fabrics
The NVIDIA Mellanox® MCA4J80-N002 is a Twin-Port InfiniBand NDR Active Copper Cable engineered specifically for NVIDIA Quantum-2 (QM9700 / QM9790) switching platforms.
This OSFP RHS finned-top connector ensures proper thermal performance in ultra-dense AI clusters, while ACC redriver technology maintains signal quality for full 800Gb/s NDR bandwidth over a 2m copper link—a distance passive DACs cannot reliably support.
Ideal for short-reach NDR spine/leaf connectivity in AI, HPC, and large-scale InfiniBand fabrics.
⚙️ Key Features
✅ True NDR Performance – 2×400Gb/s Twin-Port Architecture
Each OSFP connector carries two 400Gb/s NDR streams, delivering 800Gb/s total throughput per cable.
✅ OSFP RHS (Finned-Top) – Required for Quantum-2 Thermal Profiles
Designed for use with NVIDIA Quantum-2 systems that require Riding Heat Sink (RHS) form factor for proper airflow and heat dissipation.
✅ ACC Technology (Active Copper with Redrivers)
Ensures signal integrity and stability at NDR data rates over a 2m length.
✅ Quantum-2 Certified Compatibility
Works seamlessly with:
QM9700 Modular Chassis (Quantum-2)
QM9790 Fixed Switch (Quantum-2)
NDR Server Adapters (ConnectX-7 / BlueField-3 OSFP)
✅ Ideal for AI/HPC Clusters
Engineered for NVIDIA GPU-accelerated infrastructures supporting:
Distributed AI training
NVMe-oF over InfiniBand
Magnum IO / GPUDirect Storage
Low-latency supercomputing fabrics
⚠️ Compatibility Advisory (Important – Reduces Returns)
This cable uses a Finned-Top OSFP RHS design.
Some NICs or systems require Flat-Top OSFP modules.
Make sure your device supports RHS (Riding Heat Sink) OSFP before ordering.
🧭 Recommended Use Cases
Quantum-2 NDR spine/leaf cabling
AI training clusters (DGX / HGX platforms)
HPC supercomputing networks
Short-reach (same-rack / adjacent-rack) NDR links
Situations where 1.5m DACs are too short and optics are unnecessary
