NVIDIA MCP4Y10-N002 Passive DAC Cable — 2x400Gb/s OSFP Twin-Port to 2x400Gb/s OSFP Twin-Port, 2m

The NVIDIA MCP4Y10-N002 is a 2-meter passive Direct Attached Copper (DAC) cable engineered for high-speed 2x400Gb/s InfiniBand and Ethernet links. It connects twin-port OSFP switches to switches or DGX-H100 systems, delivering low-latency, near-zero power consumption, and cost-effective connectivity for data center scale-out.

The NVIDIA MCP4Y10-N002 belongs to the MCP4Y10 series of twin-port OSFP passive DAC cables. It provides a 2x400Gb/s link over a 2-meter copper cable, using eight high-speed electrical copper pairs each operating at up to 100Gb/s with PAM4 modulation. The cable is compliant with SFF-8665, SFF-8636, and OSFP MSA specifications, and supports both InfiniBand and Ethernet protocols automatically via firmware.

Designed for switch-to-switch and switch-to-DGX-H100 connections, this cable is ideal for Quantum-2 InfiniBand and Spectrum-4 Ethernet environments. The 26AWG wire gauge at 2m offers a balance of flexibility and signal integrity, with a minimum bend radius of 89mm. The finned-top connector design ensures compatibility with standard OSFP cages, while flat-top variants are available for liquid-cooled systems (see Selection Guide).

• 2x400Gb/s data rate based on 8 channels of 100G-PAM4 modulation
• 2-meter length with 26AWG wire gauge for optimized signal integrity
• OSFP twin-port form factor, SFF-8665 compliant
• Passive copper design — lowest cost, lowest latency, near-zero power consumption (max 0.1W)
• Protocol auto-detection for InfiniBand and Ethernet
• Hot pluggable, single 3.3V supply
• RoHS compliant, LSZH jacket, LF/HF PCB
• Operating case temperature: 0–70°C

The MCP4Y10-N002 uses a passive copper design with eight high-speed differential pairs. Each pair carries up to 100Gb/s using PAM4 (Pulse Amplitude Modulation) signaling, enabling an aggregate 2x400Gb/s link. The cable is tuned per length to minimize internal signal noise and back reflections. EEPROM memory provides product configuration information to the host, supporting CMIS Rev 5.0 and SFF-8636 management interfaces. The firmware automatically enables the appropriate protocol (InfiniBand or Ethernet) based on the attached switch.

The cable features a characteristic impedance of 90–110Ω and a propagation delay of ≤4.5ns/m. The 2-meter variant uses 26AWG conductors with a cable diameter of 8.9mm. The minimum bend radius near the connector is 10x the cable outer diameter, and the assembly space required behind the rack door is 156mm.
