NVIDIA 3.3ft 400GBase Direct Attach Splitter Cable

Overview

The NVIDIA MCP7Y60-H001 is a 3.3 foot splitter cable designed to convert a single 400 G OSFP port into two 200 G QSFP56 links. This passive twinax copper cable supports both InfiniBand HDR and Ethernet traffic, ensuring reliable signal integrity over its full one meter length. Its power-free design makes it ideal for dense rack environments where managing heat and power consumption is critical.

Key features

• Breaks out one 400 G OSFP port into two separate 200 G QSFP56 connections, enabling flexible network configurations.
• Passive twinax copper construction that maintains signal quality without requiring external power or generating heat.
• Supports high-speed InfiniBand HDR and Ethernet protocols, making it suitable for diverse data center applications.
• Compact 1 meter length fits well within racks or between adjacent racks for short-reach connections.
• Simple plug-and-play installation without the need for additional transceivers, reducing complexity and cost.

Key specs

• Cable length: 3.3 feet (1 meter)
• Port breakout: 1 x 400 G OSFP to 2 x 200 G QSFP56
• Cable type: Passive twinax copper
• Supported protocols: InfiniBand HDR, Ethernet

Connectivity and compatibility

This splitter cable is designed to integrate seamlessly into high-performance computing clusters, cloud data centers, and enterprise networks. It connects top-of-rack switches to servers, storage nodes, and GPU systems that require consistent 200 G bandwidth. Its compatibility with OSFP and QSFP56 ports ensures it fits modern networking hardware without additional adapters.

Ideal uses and environments

The NVIDIA MCP7Y60-H001 excels in environments where space and thermal management are priorities. It works well for short-reach connections within racks or between adjacent racks, making it a strong choice for data centers aiming to upgrade to high-speed fabrics without increasing power or cooling demands. Network administrators looking for a cost-effective, low-complexity solution to split 400 G ports will find this cable particularly useful.
