NVIDIA MCP4Y10-N002 Twin-Port OSFP Passive DAC Cable

The NVIDIA MCP4Y10-N002 is a high-performance, twin-port passive Direct Attach Copper (DAC) cable designed for 2x400Gb/s data transmission. It supports both InfiniBand NDR and Ethernet protocols, offering low latency, minimal power consumption, and cost-effective connectivity for modern data centers. Ideal for high-density switch-to-switch and switch-to-server applications, this cable ensures reliable performance with rigorous testing and quality assurance.

MCP4Y10-N002 Key Features

• 2x400Gb/s data rate per port using 8x100G PAM4 modulation
• Hot-pluggable OSFP connectors with finned-top or flat-top options
• Low power consumption: <0.1W
• Compliant with SFF-8665, SFF-8636, and OSFP MSA standards
• RoHS compliant with LSZH (Low Smoke Zero Halogen) jacket
• Supports InfiniBand NDR and Spectrum-4 Ethernet auto-negotiation

MCP4Y10-N002 Technology

The cable utilizes eight differential copper pairs per port, each operating at 100 Gb/s with PAM4 modulation. It incorporates EEPROM for intelligent device management, providing host identification, cable characteristics, and diagnostic data via the SFF-8636 I²C interface. The design ensures signal integrity through impedance matching and minimal propagation delay.

Working Principle

The passive DAC cable transmits electrical signals directly between OSFP ports without active components. Each lane uses differential signaling (Tx/Rx pairs) to minimize noise and crosstalk. The host system reads the EEPROM to identify cable type, length, and supported protocols, enabling automatic configuration for InfiniBand or Ethernet operation.

Applications

• Switch-to-switch connections in NVIDIA Quantum-2 InfiniBand and Spectrum-4 Ethernet fabrics
• High-performance computing (HPC) and AI clusters
• Data center spine-leaf architectures
• Connecting NVIDIA DGX H100 systems to switches

FAQ

Q: What protocols does this DAC cable support?
A: It auto-negotiates between InfiniBand NDR and Ethernet (e.g., 800GBASE-CR8).

Q: Is the cable hot-pluggable?
A: Yes, the OSFP connectors support hot-plugging.

Q: What is the minimum bend radius?
A: 10x cable diameter near connectors, 5x elsewhere.

Precautions

• Avoid bending beyond the specified radius to prevent damage.
• Ensure ESD precautions during handling and installation.
• Operate within specified temperature and humidity ranges.
• Verify compatibility with host device OSFP cages.
