Mellanox MCP4Y10-N002 2m 800Gb/s OSFP to OSFP Passive DAC Cable

NVIDIA 2m OSFP to OSFP Passive Direct Attach Copper Cable

Twin-port 2x400Gb/s (up to 800Gb/s aggregate) for InfiniBand NDR and Ethernet 800GbE applications. Low latency, near-zero power consumption, plug-and-play.

The NVIDIA MCP4Y10-N002 is a high-performance OSFP (Octal Small Form-factor Pluggable) to OSFP passive direct attach copper cable (DAC). Designed for 800Gb/s twin-port InfiniBand NDR (Next Data Rate) and 800GbE Ethernet applications, this cable provides a cost-effective, ultra-low latency, and near-zero power consumption interconnect solution for data center networks.

Each cable contains eight high-speed copper pairs operating at 100Gb/s per lane using PAM4 modulation, delivering an aggregate bandwidth of 800Gb/s per port (2x400Gb/s twin-port configuration). The 2-meter length uses 26AWG wire gauge and features finned-top connectors for optimal thermal performance in high-density switch environments.

NVIDIA Cable Management Guidelines OSFP MSA Specification Summary NDR InfiniBand vs 800GbE Comparison DAC vs AOC Deployment Guide

A: The -FLT suffix indicates flat-top connectors, designed for liquid-cooled switches or DGX H100 systems where finned-top connectors do not fit. The standard MCP4Y10-N002 uses finned-top connectors for better thermal dissipation in air-cooled switches.

A: Yes. The EEPROM firmware supports both protocols. The cable automatically detects and enables the appropriate protocol based on the switch port it is connected to.

A: For 800Gb/s operation (using PAM4 modulation), the maximum recommended passive DAC length is 2 meters for 26AWG. For longer distances, active optical cables (AOC) are recommended.

A: Yes. OSFP connectors are designed for hot-pluggable operation. Standard ESD precautions should be observed during installation or removal.

Follow standard ESD handling procedures during installation. Do not exceed the minimum bend radius (10x cable OD for repeated bends, 5x for single bend). Use protective caps until installation to prevent contamination. For detailed guidelines, refer to the NVIDIA Cable Management Guidelines document.
