NVIDIA OSFP to 2xOSFP Passive Copper Splitter Cable

Overview

The NVIDIA MCP7Y00-N003 is a passive copper splitter cable designed to connect a single OSFP port to two separate OSFP devices, effectively splitting one 800 Gb/s interface into two independent 400 Gb/s lanes. This cable is ideal for high-performance environments such as HPC clusters, AI training nodes, and large storage fabrics where maintaining high bandwidth and low latency is critical. Its three-meter direct attach design ensures minimal latency and eliminates the need for additional power or active components, making it a practical choice for dense data center racks.

Key features

• Splits one OSFP port into two OSFP interfaces, doubling connectivity options without extra switch ports
• Passive copper construction that requires no external power, reducing heat generation and simplifying cooling
• Supports InfiniBand NDR protocol, enabling compatibility with advanced networking standards for demanding workloads
• Three-meter cable length optimized for short-distance connections with consistent, low-latency performance
• Direct attach design that allows quick installation without the need for specialized transceivers or maintenance tools

Key specs

• Total bandwidth: 800 Gb/s aggregate throughput
• Channel bandwidth: Two independent 400 Gb/s lanes
• Cable type: Passive copper direct attach
• Cable length: 3 meters
• Supported protocol: InfiniBand NDR

Connectivity and compatibility

This splitter cable is tailored for data centers and environments using OSFP ports, commonly found in GPU clusters, scientific computing setups, and storage networks. It enables efficient use of switch ports by splitting a single high-speed interface into two, which helps maintain port density and reduces cable clutter at the top of the rack. The passive copper design ensures compatibility with existing OSFP infrastructure without requiring additional power or active components.

Ideal uses and environments

The MCP7Y00-N003 is well suited to data centers that demand high bandwidth over short distances, such as those running real-time analytics, scientific simulations, or AI workloads. Its passive design and low latency make it a strong choice for facilities aiming to optimize power consumption and cooling while maximizing network throughput. This cable fits naturally in setups where reliability and straightforward installation are priorities, especially in dense rack environments where space and port availability are limited.
