🚀 Overview
The NVIDIA Mellanox® MCP4Y10-N00A is a 0.5-meter Passive DAC designed for 800Gb/s InfiniBand NDR. With its ultra-short length, zero-power design, and OSFP RHS thermal profile, it is optimized for inter-switch connectivity, including:
Switch Stacking
Inter-Switch Links (ISL)
Adjacent Quantum-2 chassis connections
Patch-panel to switch direct paths
This cable provides the lowest possible latency, near-perfect signal integrity, and industry-leading reliability for dense HPC and AI fabrics.
⚡ Key Benefits
🔹 Ideal for Switch Stacking & ISL
At 0.5m, this DAC is specifically engineered for:
Quantum-2 → Quantum-2 stacking
Side-by-side switch uplinks
ISL topologies in 800G NDR fabrics
🔹 Ultra-Low Latency Passive DAC
No active components → no jitter, no heat, no power draw.
Pure copper = speed-of-light signal path.
🔹 OSFP RHS Connector (Finned-Top)
Thermally optimized for NVIDIA Quantum-2 NDR.
(Not compatible with flat-top OSFP cages.)
🔹 Ultra-Short for Maximum Stability
Short length =
Minimum attenuation
Near-zero latency
Ideal for ports located directly next to each other
🔧 Installation Advisory (Important)
800G passive DACs at 0.5 meters are extremely stiff due to thick low-AWG copper.
Install only when:
Ports are perfectly aligned
Switches are directly adjacent
No sharp bends are needed
Incorrect bending may damage OSFP cages or the cable.
