NVIDIA Mellanox MCP4Y10-N01A 800Gb/s NDR Passive Copper DAC, OSFP RHS, 1.5m: This is a 1.5-meter passive Direct Attach Copper (DAC) cable engineered for 800Gb/s InfiniBand NDR connectivity using OSFP Riding Heat Sink (RHS) finned-top connectors at both ends. This is a passive cable with no retimers, DSPs, or active electronics — it is not an Active Copper Cable (ACC) and not an active optical cable (AOC). This is a new factory-sealed unit.
Engineering Context
The MCP4Y10-N01A carries 8x100Gb/s PAM4 lanes for an 800Gb/s aggregate data rate. Power consumption is 0W and added latency is limited to copper-propagation delay because no retiming or DSP processing is performed. The OSFP RHS form factor uses an external finned heat sink riding atop the connector, designed for the thermal envelope of NVIDIA Quantum-2 NDR switches and ConnectX-7 NDR adapters. At 1.5m, this represents the practical upper bound for passive 800G copper before signal-integrity loss requires active conditioning. The conductor gauge is heavy due to the 800G reach budget, producing a thick and semi-rigid cable.
Deployment & Use Cases
Intra-rack ConnectX-7 host adapter to Quantum-2 leaf-switch links in NDR InfiniBand fabrics. Top-of-Rack to first-row spine connections inside a single cabinet. GPU compute node uplinks in AI training clusters running NDR fabrics. Inter-switch links between adjacent Quantum-2 chassis where 800G passive reach is sufficient.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number (MPN): MCP4Y10-N01A
NVIDIA P/N: 980-9IA0Q-00N01A
Form Factor: OSFP RHS to OSFP RHS
Data Rate: 800Gb/s (8x 100Gb/s PAM4)
Cable Type: Passive Direct Attach Copper (DAC)
Length: 1.5m
Power Consumption: 0W
Protocol: InfiniBand NDR
Condition: New, factory sealed
Compatibility & Constraints
Compatible with NVIDIA Quantum-2 NDR switches and NDR-class ConnectX-7 adapters that accept OSFP RHS (finned-top) modules. Not compatible with flat-top OSFP cages — the riding heat sink will not clear standard OSFP slots. Not interchangeable with QSFP56 or QSFP-DD ports. The cable is thick and semi-rigid; install along straight, unobstructed paths. Not recommended for cable management arms or sharp-bend routing. Fixed 1.5m assembly with no breakout option.
