NVIDIA 800Gb/s to 4x200Gb/s 1m DAC Splitter Cable

Overview

The NVIDIA MCP7Y50-N001 is a direct attach copper splitter cable designed to expand a single 800 Gb/s OSFP port into four separate 200 Gb/s OSFP ports. This one-meter cable is tailored for high-speed InfiniBand environments, enabling efficient data distribution without the need for additional hardware. Its passive design ensures zero power consumption and minimal latency, making it suitable for demanding workloads like AI training, real-time analytics, and high-performance storage.

Key features

• Splits one 800 Gb/s OSFP port into four 200 Gb/s OSFP ports, providing flexible connectivity options within a rack.
• Passive construction eliminates the need for external power or active electronics, reducing complexity and potential points of failure.
• Direct attach copper conductors maintain signal integrity at HDR speeds, supporting high data rates with low latency.
• One-meter length keeps cable runs short and manageable, ideal for top-of-rack switches, GPU trays, and dense server clusters.
• Designed to optimize airflow and cable management in data center environments where space is at a premium.
