Brand:

NVIDIA Mellanox

The NVIDIA Mellanox MCP7Y40-N001 is a 1-meter passive copper splitter cable designed for NDR InfiniBand and 800GbE environments. It connects an 800Gb/s twin-port OSFP interface to four 200Gb/s QSFP112 ports, enabling high-density breakout connectivity for AI, GPU, HPC and data-center infrastructure. NVIDIA lists the MCP7Y40-N001 as a pre-release (P-Rel) product.

OVERVIEW

The MCP7Y40-N001 is a 1m passive copper breakout cable that divides an 800Gb/s twin-port NDR connection into four 200Gb/s QSFP112 links. Compatibility: designed for supported NDR/800GbE OSFP and QSFP112 platforms. Model comparison: N01A, N002, N02A and N003 provide 1.5m, 2m, 2.5m and 3m lengths; select N001 for 1m installations.

USE CASES

AI GPU clusters – Provides four 200Gb/s breakout links from an 800G-class source, supporting dense accelerator networking architectures.
NDR InfiniBand fabrics – Enables supported 800Gb/s NDR switch connections to multiple 200Gb/s endpoints.
HPC environments – Provides high-bandwidth breakout connectivity for compute-intensive clusters.
800GbE data centers – Supports supported Ethernet deployments requiring 800G-to-4×200G connectivity.
Quantum-2 infrastructure – Suitable for supported NVIDIA Quantum-2 NDR switch environments requiring QSFP112 breakout connections.
GPU server connectivity – Useful when high-speed switch ports need to connect with multiple 200G-capable network endpoints.
High-density rack networking – The 1m length is appropriate for short in-rack connections where minimizing excess cable is important.
Network fabric expansion – Allows an 800G connection to be distributed across four 200G links, providing greater port utilization flexibility.
