🌟 NVIDIA Mellanox® OSFP Passive Splitter DAC – 800Gb/s to 2×400Gb/s NDR PAM4, 2m
Model: MCP7Y00-N002 | NVIDIA P/N: 980-9I929-00N002
The NVIDIA Mellanox® MCP7Y00-N002 is an OSFP passive copper splitter (Direct Attach Copper, DAC) engineered for InfiniBand NDR 800Gb/s environments.
It enables a single 800G OSFP port to be cleanly split into two independent 400Gb/s OSFP links, supporting next-generation AI, HPC, and hyperscale data center fabrics.
Built for PAM4 signaling and ultra-high lane density, this 2-meter passive splitter delivers deterministic latency, zero power consumption, and maximum signal integrity in dense rack and row-level deployments.

🌐 Engineering & AI-Cluster Context (Why This Cable Exists)
✅ Why Split 800G into 2×400G
In modern AI fabrics, 800G spine or leaf ports are often split to connect:
Two 400G leaf switches
Two 400G compute pods
Parallel GPU islands
This splitter allows flexible topology scaling without wasting high-value OSFP ports.
✅ OSFP + PAM4 for NDR
OSFP is required for thermal and electrical headroom at 800G speeds.
The cable is tuned for PAM4 modulation, delivering 400G per leg with stable eye margins.
✅ Passive = Deterministic Latency
No retimers
No DSP
No power draw
Critical for synchronous AI training and latency-sensitive HPC workloads.
✅ 2m = Practical Row-Level Reach
2 meters is ideal for:
Adjacent rack connections
In-rack 800G → dual-pod fan-out
Avoiding excess stiffness and airflow obstruction seen in longer 800G copper runs
🧠 Typical Deployment Scenarios
NVIDIA NDR AI clusters
800G leaf → dual 400G compute fabrics
Hyperscale spine/leaf architectures
Large language model (LLM) training pods
HPC and research supercomputers
